Prius (2004-09) :: 2007 - Red Triangle / Check Engine - Codes POAOF And P0121
My prius has 172k miles on it, yesterday i got the dreaded red triangle and check engine light along with the temp indicator on the navi screen. I pulled over immediately. after sitting for a bit, the lights went away except for check engine. I checked the engine compartment and felt no real heat anywhere. Coolant reservoir was full i drove a few more miles as i was taking a customer to the airport (i work for uber) and they came on again.
After sitting for a few again they went away and i continued on to the airport. on the way back home, about 40 miles or so later, it happened again. again i sat for a few and it went away and i took it to the dealership in my town. they have always been really cool there (an anomaly i know) I never before used dealerships for anything before owning a prius) and he pulled the code for me and it showed POAOF failure to start. that had actually never happened, but was told that it doesn't necessarily mean the car wouldn't start, it can happen while running.
He cleared the code, as i had recently changed the 12v battery and after reading a bit here i know it can cause some weird stuff so i was hopeful that would do the trick. so today i went out and worked again. Drove probably around 50 miles or so and on the way home it happened again. Back to the dealership. This time they put the main tech on it and he also got the code P0121 indicating the throttle position sensor. He took apart the throttle body and tested it and said it was showing not enough ohms or something like that (I know jack all about electrical) and that the throttle body was bad and would need replacing, also saying there was oil in the intake and it would need to be cleaned.
Prius (2004-09) :: Sudden Loss Of Traction Power And Engine Races
I have a Prius 2005 with an Engineer 4kwh kit installed [v4 bms]. Lately, I have experienced several instances where the Prius suddenly looses much of it's traction power and the engine races, and the red triangle and engine service lights go on at the dashboard. This happens with the kit turned on, and often after a few kit on/off cycles to get more ev mode. The Prius battery is sometimes low, sometimes not, when this happens. Not sure if it also occurs with the kit off.
The Prius seems to retain some traction power up-down by the throttle pedal, but most power goes missing. On the other hand the engine races and does not seem to power the wheels or vary by throttle. When I pull off the road using brakes normally, and turn off the car/engine and restart [kit now off], the car seems to reset and can resume driving normally, but the error code lights [triangle-engine] lights stay on.
Prius (2004-09) :: 2006 - Red Triangle And Loss Of Power
Purchased a used 2006 prius with ~180K miles on it from south bay a few months ago. At the time of purchase the guy warned us that it 'ate' motor oil.
After 2 months of driving without issues (driven couple of hundred miles), on an uphill road the engine overheats and throws the red triangle, vsc and check engine lights on the dash, along with loss of power. After cool down I check oil level and sure enough it is low, since this is on top of a hill we essentially coast all the way back home without any real issues. Once home I top up the oil. I do a test drive around the block without issues (no loss of power) though the check engine/red triangle/vsc lights are still on. But after I take it for a longer drive the loss of power returns.
Since my bluetooth obd2 connector wasn't working I borrow one from my friend and try to get a read. Unfortunately the thing puts out no obd2 error codes. Living in the bay area I apparently cant just take it to an autozone, to get code readings. I take it to meineke auto repair, they too are unable to get an obd2 read, and want to charge me $100 for a full reading, which I decline.
I do a few diagnostics steps including 'resetting' the computer by leaving it off of the 12v battery for a few mins, this clears the red triangle et al on restart. I do a test drive, at first everything is working just fine, but after about 10 mins or so of driving the red triangle/check engine/vsc lights returns, along with loss of power. (under ~20 mph only, cant go uphill).
Take it to a mechanic and they come back with code: "APOA92. Trans Axel issue - MG1 performance is off. Measured torque is different than executed torque, enough to be a problem. 95% sure it is the transmission." I still haven't checked the 12v battery.
Prius (2004-09) :: Loss Of Power / Red Triangle And Hybrid System Warning
During a highway trip three months ago, my 2004 Prius suddenly lost engine power, the red triangle Master Warning light came on accompanied by a warning sound, and then the Hybrid System Warning sign appeared on the Multifunction Display. I pulled off to the side of the road and stopped. I turned the car off and then tried turning it on again. Engine power was restored although the warning lights remained. We took a chance and carried on with our trip. The same sequence of events reoccurred about 10 times on our 1,300 km journey. I took the car to a Toyota dealer where they found a C2318 DTC. They checked the battery and the HEV fuse but could not locate the problem.
We returned home and on the way the same thing happened a few more times. My service manual noted that the description for C2318 is Low Voltage Error (Power Supply Malfunction) and the trouble areas are HEV fuse, IGCT relay, Wire harness or connector, or Auxiliary battery. Since the car was nearly 7 years old I thought I had nothing to lose by replacing the battery, which I did. However, on a short 150 km trip last week the problem appeared again, once while approaching our destination and once when we were almost home. There seems to be a pattern in that the problem appears every 150 km or so of highway driving. It has never done it while driving in the city.
Prius (2004-09) :: Car Shut Off And Check Engine Light Came On - Code P0121 TPS
I got an 2009 toyota prius I was driving home one day and car shut off and check engine light came on after 10 mins of the car being off I try to turn it on, it started with the check engine light still on main battery light came off, I ran to AutoZone and got my car scan for codes and P0121 was my code tps my car has 120k miles what should I do clean the throttle body? Replace the sensor? How would I test the sensor if it's bad?

Ford 6.0L Power Stroke Diesel :: 2004 F250 - Sudden Loss Of Power
I have a 2004 F250 6.0 DuperDuty with about 170,000 miles on it, so far no major break-downs, just a starter and a blinker relay, but now I have a problem.
When I start now, the truck starts fine and it sounds fine, but it has almost no power even if I floor the gas peddle, there is a delay of like 2-3 seconds and then responds slowly, like some tractor. Eventually it starts to move slowly, and after it warms up (after a few minutes), the gas peddle responds more normal.
Also - at about 45mpg, at lower RPMs about 1250, the engine starts to shake (weird), it doesn't do it at idle about 850 RPM, or when I get it up to about 1800RPM+, but at about that 1250 RPM it does do it, luckily I driver locally for a few miles.
What could this be ? What exactly happens when I press on the gas peddle, what systems are involved and in which order?
Ford 6.0L Power Stroke Diesel :: 2004 F250 - Sudden Loss Of Power
I've got a 2004 F250, 6.0, with 150k miles. I was pulling a motorcycle trailer uphill in the mountains when suddenly I couldn't go over 10 to 15 mph. All the gauges read good but it just couldn't get any power.
Got to the top and checked over everything. Didn't see any issues. Drove it home (200 miles) the next day. It drove okay on highway but it felt like the turbo wasn't coming on. Coolant was low and EGR was gunked up but only slightly wet. From what I read, it sounds like EGR cooler is failing but would that cause the turbo not to come on or feel like that loss of power? Reading another thread, I thought it might be the fuel pickup but I dropped the tank and the sending unit looked very good.
I'm ready to throw on a bulletproof egr cooler, oil cooler and rebuild the turbo if necessary but hate to get to the end and find out none of that worked.
Ford 6.0L Power Stroke Diesel :: 2004 F250 Just Died All Of A Sudden - Intermittent Power Loss
Ok I have an early 2004 F250. Recently changed out the #8 injector and then had to replace the ICP Sensor. Was running great then while driving down the road just died all of a sudden. Would start right back up with no issues. Continue driving and I am getting intermittent power loss. Also noticed that when it would lose power suddenly the glow plug light would come on.
Codes are P0102, P0113, P0272, and P1000.
P0102 Mass or Volume flow circuit low input
P0113 Intake Temp circuit High input
These are just soft codes not setting a light off. MAF is plugged in and I will check wiring here later after work but could this be causing my intermittent issues?
Prius (Gen 3) :: Sudden Power Loss - Battery Didn't Show Very Low
Was sitting in my car on my lunch break playing the radio and had my seat heater on, and all of a sudden my radio kinda went staticy and died and my car completely died. Had to power it back down then back up to get it running, battery didn't show very low, but when I went into start mode (non accessory) it immediatly started the ICE and charged.
View 19 RepliesPrius (2004-09) :: Exclamation Point Triangle Light Flash When Coming To A Sudden Stop And Emit A Beep
My 2008 Prius has approximately 116,000 miles on it, about 8,000 miles ago, I put on a Mobil 1 Extended Performance filter and 5W 30 Mobil 1 Extended Performance Full Synthetic Oil. Over the past week, My "Exclamation Point Triangle Light" (Not sure what it's called) has flashed a couple of times when coming to a sudden stop and the car would emit a "beep".
My first assumption was low brake fluid, but today when I got home and checked the fluids, I found the oil to be approximately 1.5 quarts low... I have not noticed any leaks under the car (I park in the same spot at work daily), and haven't noticed any smoke coming from the rear...
What the problem might be? Is it possible I might have damaged the engine by driving on such low oil for an unknown period of time (guessing a couple of weeks or so)? I used to religiously check the oil in all my vehicles, but have gotten out of the habit on later model vehicles...
Prius (2001-03) :: 2002 - Sudden Loss Of Power While Driving Followed By Alert
I've been having this problem where as i'm driving (mostly highway) all of a sudden I get the feeling like i've let go of the gas pedal but I haven't. The mpg meter goes from about 40 to 100 as if its on straight battery power and I have to really press the pedal down to get any decent acceleration. Once in awhile i'll get the big orange triangle warning and the little pic of an exclamation point in an outline of a car. But after a day it may go away.
One time it didn't and I brought it in. I spent 80 bucks for them to find nothing wrong and say the alert had something to do with an oxygen sensor (its was awhile ago, i dont quite remember exactly)
Prius (Gen 2) :: 2005 - Triangle Of Death With Some Power Loss And Rear Fan On
I have a 2005 Prius that has been very reliable! With the exception of oil changes, brakes & tires I've only needed to replace the Inverter Cooler Pump, which was under recall (about 40K miles ago). Without any prior problems, the triangle of death came on along with the other dash alarm lights. I noticed an immediate great power loss & the fan behind the rear seat came on.
I stopped the car & let it sit about 30 minutes. It started right up & I drove it home. It felt sluggish & the max was 50 or so , I didn't want to push it, so I stayed below 45 mph. It had very little power, the engine ran constantly, with no battery assist. The drive home was approx 40 minutes. When I tried to start it a few hours later, it started immediately. The warning lights are still on, it runs rough upon start and the rear fan comes on immediately.
Prius (2004-09) :: Red Triangle With Code P0aa6 And Sub Code 612 Came On
have a 07 prius with 113k miles. It recently displayed the red triangle with code p0aa6 sub code 612.
I took apart the battery and nothing looked corroded, then on the inside of the bus bar i found a small amount of corrosion. After testing the cells i found 2 modules that were leaking voltage.
Since I had everything open I figured I might as well test to see if any cells were on there way out. The static voltages were pretty close around 7.8v, there were a couple modules that were .3v apart that I'm doing more testing on. I load tested each module with 1a, is 1 amp enough for a load test? I have a 100a load tester but figured that was way too much. They were all ok under load test, dropping about .6v and returning to original voltage within a few minutes.
Then I decided to check capacity on the bad cells, they were about 500mah, got to 1000mah after 1 discharge/charge cycle. I tested the capacity on a cell I thought was good and so far it discharged about 1050mah until it reached 6v, this was from 7.77v. I'm giving it some time to rest to see if it goes back up a bit and then I'll discharge some more till it stays at 6v. Even if I get a little bit more in it will be way under the 6500mah it should have or even the 3500mah that I've read is acceptable.
Since all of the modules have parameters that are pretty close I'm thinking the capacity will be pretty close as well.
Prius (Gen 2) :: 2004 - Red Triangle And Hidden Code P3009-526
I picked up a 2004 Prius with 150k. It has no check engine light and no codes with a scangauge. I hooked it up to a mini-vci with techstream and found the following: P3009-526, C1310 and B1421. The car will only start if you reset codes, then after a few minutes of running the red triangle comes back.
View 10 RepliesPrius (2004-09) :: Red Triangle Light With CEL Code P0a80
Was driving home from school yesterday and my 2005 Prius turned the check engine light on and the red triangle light. Plugged into the scan tool it read: P0a80. I have a hybrid battery ordered. It should be delivered on Tuesday. How long can I get out of this failing battery before the car is undriveable? The Prius is my only vehicle and I don't have a problem with installing the battery, I just I'm wondering if the car will just drop dead on me before the battery gets here? The car appears to be driving normally with no loss of performance or MPG.
View 4 RepliesPrius (2004-09) :: No Fault Code But Intermittent Red Triangle
Seems like issues with my 06 prius battery are back, however this time it is rather strange but very predictable. I cannot read any trouble code as the red triangle on the dash (and "problem" on the display) never stays on more than a few seconds (1-5 seconds at most).
At first it was doing this only after long downhill driving (like my 1.5 mile downhill street at 25 mph) - charging the battery and once getting to the last green bar I would get a Bip, red triangle and "problem" on the display. This has been going on for 4 weeks roughly.
But it's gradually getting worse, the same symptoms would appear after shorter downhill driving. And now it does almost every time I get the foot of the accelerator (assuming the car has decent momentum to regenerate).
I am guessing a module is starting to fail but last time I had a failed block, it didn't do that. One day I got the red triangle along with a bunch of other lights and that was it.
Prius (2004-09) :: Warning Light Accompanied By The ICE, P0121
Recently I had a warning light accompanied by the ICE shutting down. P0121. As the repair, the throttle body was cleaned.
A week or two later, while in Park with the parking brake engaged, I got another warning light along with some text on the display, something about parking brake. I didn't completely absorb the message before powering off, waiting, then powering on. No more warning light.
Ford 7.3L Power Stroke (1999-2003) :: E350 - Sudden Power Loss / Zero Power
I am still failing to appropriately diagnose the problem(s) with my '03 Ford E-350 7.3L Powerstroke. This van has only 69,000 miles on it. A week or two back (just a few days back in work time) it suddenly went from running perfectly smooth, clean and wonderful to this:
- Zero power. Putting the van in gear and flooring the engine causes lots more smoke not nearly any rev of the engine and just a crawl forward.
- Lots of smoke out the back exhaust, whitish. I cannot discern wether it smells like diesel or oil (because I'm ignorant here), but the smell is very strong.
- After warming up and idling ~ 15 min I check under the coolant cap and see no signs of bubbling or disruption (from opening the cap in the coolant tank).
- After warming up there are no warning lights visible on the dash, and I don't have a computer to read codes (if there are any to read).
- I replaced the turbo up-pipes which had a visible leak previously. This did not hurt the symptoms, though no more visual leaks under the dog house.
- I thought maybe I put gasoline instead of diesel in the truck, not so.
- To do the above test I had to use the fuel pump to get gas out the tank to test. I hijacked the fuel pump output and turned the car on a few times to get gas out to a tank. The pump seemed to work just fine.
This was all very sudden which is perplexing, and, in use, the van was previously an ambulette and in my few miles with it (maybe 200-300 only) use was extremely light for such an engine/van, just driving around doing errands. I am not sure if this is relevant (no one has suggested so, yet) but before all this happened I uninstalled the rear HVAC that came with the van when I bought it. The AC lines were sealed under the hood. The coolant line was returned at the doghouse (you can see this at the beginning of the video).
At the moment the van has no power to go anywhere. I have not yet checked the CPS or IPC sensors, and understand this might be the next route in standard troubleshooting?
