I have a 2001 toyota that I was driving yesterday. I parked my car on the side of the road for 2 minutes to find something in the car. Randomly after a minute of being parked the car suddenly flashed the red triangle on the dashboard as well as the check engine light.
Also as well on the main computer screen where the radio stations normally are displayed a Problem alert appeared. It shows the PS icon, the Battery Icon, and the Red Car exclamation icon. Only the Car Exclamation point is red.
As some basic steps I tried (Because I don't know that much about cars) I opened the hood when the engine was off and cold and checked the air vent filter to see if it was clean. I cleaned just in case. I also check the gas cap to see that the cap was closed tightly. Also checked the tires air to see if that could be the case. Oil was looked at by me and I didn't see anything abnormal as well.
Prius (2004-09) :: Red Triangle Icon - Car Not Switching To Gas Engine
Today, I was driving on the street when I got the dreaded red triangle icon and the word "problem" appeared across the top of the MFD screen. I then noticed the bars on the battery screen kept lowering down to where they became purple when stopped with the transmission in D. The engine would usually start up at this point, but it didn't. I put it in B and gave it a bit of gas to force it to start up. Once I started driving again, the bars went back up, but it has happened two more times (every time the battery depletes to purple).

2004 Prius, 149,000 miles. Driving on a highway when suddenly it felt like a headwind was bearing down on me, and a minute later, the red triangle of death and all the other lights came on. Did not totally lose power. Pulled to the shoulder and while waiting for the tow truck, started and turned the car off several times.
After the first few times, the red triangle did not light up, but the check engine icon remained on. The tow truck driver had a very difficult time getting the car into neutral to pull onto the flatbed, and then when he took the car off the truck to park it at the dealership, he said it shifted "hard" into drive.
I don't have a code since I don't own a reader. What this might be? I really, really hope it's not the traction battery needing replacement. I have no training to replace single cells.
Prius (2004-09) :: 2008 - No Heat / Red Triangle And Thermostat Icon Lights Come On
I have several problems with my 2008 Prius that I will try to list below and I have done much of mechanic work myself but now I am a little stuck with some of the codes that are coming up and with some of the problems my Prius is experiencing:
Here are the codes that were scanned when I took car to a local parts store:
Coolant Temperature Sensor Evaporated Emission System (Vacuum Leak)
p3193
Accelerator Pedal Position Sensor
Pump Control Circuit Low
" High
I replaced the thermostat and now I get the red light displays on the dash anytime I go over 45 and the thermostat light on the panel displays there is a problem. I think there might be air in the system. Should I have a mechanic bleed air out or is there an easy procedure that I can do on my own to fix this problem?
I have also purchased a water coolant valve and this will be my next part to replace at 106.00 dollars. I am not sure this will fix my problem with my heat but I do not want to replace the heater motor because those run 630 dollars each.
Being that it is winter I want to fix the problem so that we can drive the car with some heat and not get the red light to come on intermittently. How to get to the root of these problems listed above?
Prius (2004-09) :: Red Triangle, Dash Lights And Hybrid System Icon On MFD
I have been having some hybrid battery issues. My prius is a 2006 with 198,000 miles. The original battery was replaced at around 120,000 with a junkyard battery. About a year later that battery gave up the ghost and I decided to rebuild that battery. So far that has worked quite well until recently.
My troubles started a couple weeks ago when I got the Red triangle and all the dash lights and the hybrid system icon on the MFD. Naturally I thought it was the battery again. Took it out and checked the voltages of the modules. All the modules where within tolerances. I grabbed a OBDII scanner and checked the code. It was telling me that the Hybrid current sensor was bad. I changed that out with the wiring harness from the old battery.
That lasted for a few days before the red triangle came back. I checked the code and it was indicating one of the blocks was bad. I think P3019. So I took the battery back out and replaced that block with other modules. Almost instantaneously the red triangle came back with two more bad blocks. I think it was P3012 and P3022. So I took the battery out once more and tested all the voltages of all the modules. Everything was 7.86-7.9v. So I decided to start the rebalance of the existing modules in hopes to find some bad modules.
I also bought a new 12v battery and installed that. I got everything back together and took it for a road test. It took about 30 mins before the triangle came back. I grabbed the codes and it was still indicating bad blocks. P3011 and P3018. I am a little at a loss.
Prius (2004-09) :: Overheating / Red Triangle On Dash And Thermometer Icon On Navigation Screen
My car Gen.2 was 200K. I change the water pump and thermostat on 150K. The reason to change the parts because I think my car a lot of miles. The car run great no problems. Till last month my car had overheat on freeway at night time. The temperature up to 245 F have the red triangle on dash and thermometer icon on Navigation screen. Before overheat on same day on the daytime when I take off I heard sound water running in the engine. The day after I check the level coolant in the reservoir tank was full but in the radiator need to fill up the coolant. After that when I drove the car the coolant overflow form the reservoir all the time. I have to check and fill up the coolant in the radiator every morning. I been the many shop ask them about the symptom of my car. Some they told me water pump failure, some said thermostat failure open all the time or some told me head gasket leak. I check all the engine didn't see any leak but I saw coolant overflow from reservoir...

My '05 Prius with just 16k miles on it just started displaying the red triangle with exclamation mark (multifunction warning lamp?). It displays about every 3 times I start the car... The Info screen shows the icon for the Automatic Headlight Leveling System. So Ive been searching, and have found a few threads related to this, but the fix Ive seen referenced I cannot find since the posts referencing the fix are about 5 yrs old. Exactly where on the car I can find the sensor, and how it can be fixed?
View 19 RepliesPrius (2004-09) :: 2006 - Red Triangle, VSC, Check Engine Light Came On
My beloved 2006 Prius with about 117,000 miles on it needs to go to the shop (I'm not a DIY mechanic). As I was driving home yesterday from work, all of the sudden the red triangle, VSC, check engine and a little car with an exclamation point on it on the display came on about 2 miles from home. There also appeared a kind of wind sound from the passenger rear area when this happened.
I drove it home and pulled into the driveway. Lights, radio, etc all work. I stopped it for about 30 minutes and then started it up again to pull it in the garage (all warning lights still on).
My question is can I drive it safely to my wonderful mechanic's shop about 10-15 miles from my house (assuming it starts)? I don't want to further damage anything.
Prius (2004-09) :: Red Triangle Pop Up With Yellow Headlight Symbol
Last month my red triangle would pop up along with the yellow head light symbol. Most times it would be for a few seconds, other times it would stay on for a few minutes. Today I rotated my tires and I thought I would check out leveling sensor while the tires were off.
I took my left rear tire off and this is what I saw when the sensor was removed.
So everything looked normal to me. Looks can be deceiving. I've seen pictures on here of leveling sensors where the guts are completely rotted out. That's what I was thinking I was going to see. Here is a picture of the bolt side of the sensor:
Again, it looked normal to me. If you don't know what you're looking for, especially if parts aren't mangled, it can look normal. So I took the four screws off of the sensor and this is what I saw:
The inside of the sensor was in pristine condition! The springs are shiny gold and there was only a small amount of dust inside the sensor. I started to think about how the sensor works and I figured out that the sensor must move in some way. Hmmm. But there was no bracket on it to turn the sensor.
Toyota - Prius :: 2004 - Red Triangle On The Dash And Headlight Symbol On Monitor
I have a 2004 Prius with self-leveling headlights. I have no problems seeing at night but i have a red triangle on the dash and the headlight symbol on the monitor. I was able to aim the lights level when the self-leveling sensor broke. but is there a way to disable the sensor so i don't have any of those symbols on the dash or monitor it just is pain to look at the the sensor cost to much and it doesn't have any affect on driving during the day or night.
View 2 RepliesPrius (2001-03) :: Warning Triangle / Hybrid System Icon Comes Up - Engine Goes Off
My wife has a '03 that has been great. No issues. I am a excellent mechanic, on conventional cars and motors. Here's my story:
Bought the car used and working last week. Put in a new 12v Group 26 battery w/conversion. I verified the 12v battery was at 12.8v and when engine was running, 13.6v to charge the battery. Car was starting and driving wonderful for about 600 miles. No shuttering, no shaky starts. Mileage was about 38.6. Anyway, yesterday was driving and all of a sudden the warning Triangle comes on, Hybrid system icon comes up and the engine goes off. I was able to drive the car about 1/2 mile on the traction battery back to my work.
It happened to have a code reader handy and it reads a P3125, Inverter. I realize there are sub codes that further diagnose the issue, but I don't have that type of OBDII reader although mine is a very expensive model. Anyway, I reset the code and got the car to start. Motor begins to go up in RPM and throws the code again. I shut it off, reset the code, try to start the car and I feel it slightly jump forward, engine does not start, then throws the warning code again. I did notice the traction battery is at 25%. I do this two more times trying to get the engine to start before I call the tow company. BTW, the car rolled easy, so I don't think its the MG2 is bad, although correct me if i'm wrong but doesn't Mg1 start the engine?
Oh, incidentally, also the ignition key does not release either. The key release solenoid is energized unless I unplug the 12v battery, then I can get my key out.
Prius (2004-09) :: 2006 2G Engine Stalls / Check Engine Light And Red Triangle
2006, 2G, 43000K. This has happened twice now. Both times on an extended trip of 3+ hours in hot weather: Cruising along at about 70 MPH, the engine just quits. RED Triangle; check engine light; and vcs light. Turned everything off. Car would not restart right away, but after waiting 15 minutes or so, the car restarts and runs fine. All warning lights off except check engine light.
Immediately drove to a Toyota dealership where the following codes were found: P0AOF info 204 (Engine failed to start); and P3190 (poor engine power). The Tech checked the EFI relay; checked for oil puddled in intake; and checked for a contaminated MAF sensor. "No problems found"!
Prius (2004-09) :: 2006 - Red Triangle At 73 MPH In Neutral
I just bought a 2006 Prius about a month ago (57K). I love the car and have been educating myself on all things Prius, This car has also made me change my driving style quite a bit. I am getting around 50 MPG (combined) and very happy about it.
I have been using some of the hypermiling techniques to get the mileage, one of the things I do is to put the car in Neutral (to emulate the Glide portion of the Pulse and Glide) especially when coming down a gradient. I was bit concerned about using the Neutral gear and called Toyota Corporation to get a clarification, The answer I got from Toyota was - there is no technical issue, however they do not recommend this be done for safety reasons.
Prius (2004-09) :: 2006 - Beep And Red Triangle?
My 06 Prius with 130k miles just starting to briefly (1-2 seconds) show "PROBLEM" on the MFD and beep and sometimes show a red triangle.
This only happens when I am going down hill on a tight curve when going fast. This never happens going up hill (since I am generally going slower) nor on flat roads. Since this is my normal commute road and I have not changed the way I drive for several years, I am surprised that this is now occuring.
Some possible theories: oil is low - I will checksome level sensor is complaining? some tire rotation sensor is complaining?
Prius (2004-09) :: 2006 - Check Engine And Red Triangle
Took the Prius to the crosswalk today, one mile roundtrip, everything was fine. Came home and being lazy I put it in the driveway and locked it with the windows up instead of my normal in the garage with the windows down. At close to 100 degrees outside the interior was blistering hot when I went to start it and head back for my afternoon shift. The dash lit up like a Christmas light display. Brakes, red triangle, vsc, check engine, etc.
Put it in the garage with the windows down and let it sit for a couple of hours to cool a bit. Started it up and let it idle for about 15 minutes; everything reset except the red triangle and the check engine light. Drove it down to the dealer but they won't have a diagnosis until tomorrow. It handled the drive just fine like normal.
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) :: 2006 - Intermittent Red Triangle Of Death
Our '06 has 68K on it. Last weekend I changed the front bumper (just cracked from small accident last year) and changed the oil. Used Mobil 1 5/30 and a Fram Oil Filter.
After about 125 miles of driving intermittent Red T.O.D. Always when ICE is running.
Oil level is OK - not loosing any oil. Filter and bolt on the pan are fine - no leaks.
Prius (2004-09) :: 2006 - Triangle Of Death Came On, Battery Died
Got the triangle of death after letting the car set during my 2 week vacation. P0A80 and Battery block is 14.17V all the rest above 15.35. That's a lot of money to repair a car. Not sure if I want to cut my losses and move on or replace it and drive as long as I can.
