Prius (Gen 1) :: Red Triangle Keeps Appearing With P1455, P0420, P3191
I have a 2003 with ~230,000 miles on it. We are the 4th owners, and have owned it for 7 years / 120,000 miles.
7 months ago, in December, I experienced my first red triangle of death. It happened on a warm start, but drove fine. Took it to O'Riley, they used an Innova 3120 to check the codes, and these are the 3 that came back (P1455, P0420, P3191). After starting the car the 4th time, the warnings went away, and all seemed well. It happened again about 3 months ago while on the highway, and again went away after 4 starts. At the time I was not too terribly worried about emissions codes, we live in an area that doesn't require testing, but the 3191 was the more ominous one.
The red triangle came on again two days ago, about 5 minutes after a cold start, and again today, about 5 minutes after a warm start. I do not know what the current codes are, but I will be taking it to a store tomorrow to get them checked. I had an oil change 4 days ago. I checked the intake manifold for any sign of liquid (I saw several posts in RE to the 3191 of that being a possibility), and it is as clean as our '05s. I checked my service history, and didn't have anything done the first two times this happened.
If the same codes persist, I'm assuming the problems could be cheap to almost what the car is worth (~$2,500).
Prius (2001-03) :: Red Triangle Off - Got Codes P0121 / P3190 / P3191 / C1259 / C1213 / P3101?
The red triangle light and the car with the ! Light went off and these are the codes the local shop has found:
- P0121
- P3190
- P3191
- C1259
- C1213
- P3101
The shop I went to in Little Rock would not touch it. Need to put these together and diagnose where to start?
Prius (2001-03) :: Engine Runs Then Stalls / P3191 Code - Oil In Intake Manifold?
Looking at a 2003 Prius with 77K miles. Turn the key, the engine starts, runs smooth for about 5-7 seconds. After that it starts to run rough and rattle, then shuts off. The only code I pulled was P3191. I pulled off the air cleaner to clean the throttle body, and noticed a small pool of oil in the bottom of the intake manifold. Is that normal, or could that be causing the code issue? BTW, I cleaned the MAF and throttle body, and the engine still does the same thing.

Got a red triangle on dash. 12 volt was dead. AAA recharged it red triangle still on. Why?
So what does a red triangle with exclamation mean? Is it a fatal problem?
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 (2004-09) :: Got Warning On Dash - Red Triangle?
I took my car to the dealership because it had the red Triangle ! wanrnning on the dash and the red car ! warning on the display panel. They told me the code was P0A82 "hybrid battery pack cooling fan 1 performance / Stuck off" but it was actually working at the time the mechanic looked at it.
He said it would probably need to be replaced anyways so they wanted to replace it. I told them I would wait, so they cleared the code for me. I read a lot of posts of people having the same problem and they fixed it by cleaning the fan. My fan was a little dirty, but not bad at all. Is there a quick way to see if the cleaning fixed the problem?
Prius (2004-09) :: Dash Indicators Flashing / Triangle For A Second Then All Goes Away
Ok wife's car '07, complained her dash indicator lamps were flashing on then off for a second a once or twice in a few days, then triangle of death for a second, then all goes away. Her ABS light came on. This last time it did its flashing thing then the SRS light came on. First thing that came to mind was 12v battery. I threw the TechStream on and ran some tests. Saw 4 codes, B1801, B1811, B1421 C1241. Checked voltage at the battery, it was 12.41v with car off. Negative terminal was very loose and had a little corrosion. Cleaned it, tightened it and ran tests again. No tests came up for the SRS as it said "no response", so I am not sure how to test the system.
My concern is this is the second time the SRS B1801 and B1811 codes have come up (Open connection in D squib 2nd step). The first time I went through, replaced the steering wheel clock spring and checked connector wiring, checked the driver's side seatbelt wiring and replaced the side airbag/seatbelt ass'y. Then I sent in the SRS module to be cleared/reset. I wasn't about to mess with the Steering bag, so I didn't test it. Car was fine for 2 months, then it has reappeared. Did this bad battery connection cause this? What am I missing?? What is next?
Prius (2004-09) :: All Dash Lights With Red Triangle Came On While Driving
2007 Prius 215,000 miles. Car has been a champ for the almost 2 years I've owned it, buying it with 150K miles. No real troubles and I've been driving it constantly as you can tell. Had an extended warranty repair done back in the winter when dash lights went out completely yet car would still start & run. Replaced 12V battery back them trying to diagnose trouble and it was original battery anyway. Daughter was driving when almost all dash lights came on including the red triangle. She came back home, turned it off. Next start was just red triangle and check engine light with red car on center display. Now it's just the check engine light and red car after sitting for an hour. I plan to take it in to get check engine light checked out.

My car has 80,000 miles on it and i just recently purchased it from a dealer with no warranty. I bought it at 65,000 miles and everything seemed to be just fine up until last night. the emergency triangle popped up on my dash along with my check engine light, ((!)) and VSC. I have since then taken it to midas to get an oil change and get the codes read.

I was at an intersection and red triangle came on dash and lost all driving functions. Had to turn power off, then turn back on. Was able to drive 100 yards to a parking spot, but it went out again. Reset car again, then it happened 4 more times within 2 miles while driving. Had to call tow truck. Just kept shutting itself down. How to fix this. See picture below for the message I got when it happened. This is the first time my car has malfunctioned like this. I think maybe its throwing itself into park or neutral (judging by the P-lock message below) and cuts all throttle control to car. Has 105,000 miles on it.

Recently, my Prius hasn't been getting much use, so the 12v battery drained. The car worked ok after I gave it a jump. But, because I don't drive the car very much, the battery drained again, maybe completely.
When I jumped it again, the car ran ok, but the red triangle is displayed, along with the check engine light on the dash, and a red car icon on the MFD. The car drives, but the lights are on.
Before replacing the battery, should I take any steps?
Prius (2001-03) :: Triangle And CEL Come On With A Ding And Also Dash Lights Immediately Dim
My gen I Prius started having issues. Every time I drive about 30 miles the triangle and check engine light come on with a ding and also my dash lights immediately dim. I just replaced the 12 v battery. Still no fix.
I also switched the fuel pump relay with the horn relay which seemed to work the dash light dimming problem (oddly enough). So I'm not sure what it could be.
Prius (2004-09) :: Dash Displays Brake Warning And Red Triangle
We're on a road trip and the alarm tone goes off. The dash displays the brake warning and the red triangle (and the touchscreen has a car outline with an ! in the upper left). Also, the cruise control no longer operates. We return to El Paso and the dealer utilizes several hours and two diagnostics to tell us the Hybrid ECU needs to be replaced. Unfortunately, they can't get our Prius back to us until Monday, the day we are supposed to be back home starting work the next day.
We plan to call the other dealership in town in the morning. But is it safe to drive our Prius in this state? Can a regular garage make the repair? My father-in-law, an automotive repair professional back in Missouri, says that he isn't surprised if an ECU needs to be shipped from a Toyota distribution center since the part isn't regularly kept in stock by an auto repair shop.
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) :: Dash / Warning Lights - No Red Triangle Of Doom Shown
There's an ad for a car quite far away from me and one of the photos shows the dash lit up like a Christmas tree. Is this normal during power-up or is it normal when there's something quite wrong?! There is no red triangle of doom shown; I'm unsure if that might be out of shot though. Car is quite high mileage with just over 270,000 km on the clock and is from 2006.

Prius (2010-12) :: Yellow Triangle Light Illuminated On Dash When Hit The Brakes
Quick Question: I was driving through my neighborhood yesterday and hit a pretty good bump. I as hit the brakes, a quick Yellow Triangle Light illuminated on my dash. There were no other warning lights that I could see and the warning light was only on for a split-second. What could've caused this? BTW, I have a 2013 Prius LB 3 purchased new in August w/ only 1230 miles as of today...
View 16 RepliesPrius (2004-09) :: Red Triangle With Exclamation Point Symbol Appeared On Dash
I have a 2009 Prius Touring with about 55,000 miles on it. Had it regularly serviced last Thursday at the Toyota dealer/service center, and they said it needed to have the coolant flow control valve replaced due to sticking - so I agreed and they did it under warranty.
On Friday afternoon, I was driving out to the desert and about 50 miles into my trip, the red triangle with exclamation point symbol appeared on my dash, and the word "Problem" beeped on my screen. Then it went off, and then back on a few minutes later. Then it happened again and the high coolant temperature warning light came on the screen...and then went away. I turned off the A/C and opened the hood to check for steam or heat, but there was nothing. Since I was far from my destination, I called the closest Toyota service center and promptly drove there, but the light was off when I arrived. They said they checked everything out and ran the codes, but nothing came up.
When driving home on Sunday, the car did the same thing - Problem Triangle and High Coolant Temperature warning light on and off for varying amounts of time and with no correlation to how fast I was driving or how hard the engine was working. I left the A/C off the entire time.
Today, the car did the same thing after driving for about 10 miles. I brought it back to my regular service center, they ran codes and checked everything out...but they cannot find anything. They said they can't determine anything with the light off, but it doesn't stay on consistently so it's nearly impossible to bring it in with the light on.
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.
