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 (2004-09) :: 2007 - Red Triangle Shows Up - Hybrid Battery Cells Overheats?
I have a 2007 Prius and the red triangle showed up. It has less than 50,000 miles. I noticed that almost right after I start it up the hybrid battery fan kicks on. This leads me to believe that maybe one or more cells in the hybrid battery are overheating due to charging problems. Is there a way I can check this out without going to the dealer?

2003 Prius. Situation as follows:
Malfunction Indicator Lamp lit on start-up during sub-freezing weather for failure to start (P3191 and P3101 codes loaded). Occurred twice (so far).
Dealer diagnosed as possible fuel pump problem, though fuel pressure nominal and held pressure after engine shut-off.
Independent mechanic (using EG011-03) diagnosed following:
Diagnosis codes: P3191 (engine does not start) and P3101 with information code 205.
Circuit opening relay was fine.
Fuel Pressure was normal (~45 psig) and held after engine shut off.
Coolant temperature - 9 deg C
Engine RPM - 1200
MG1 Torque value - 0
Installed ECU Part Number - 89661-47053, calibration # 14705301, 14705302
EG011-03 decision tree leads to replace Engine Control Module with newer part number.
Took back to dealer, who indicated still possible fuel pump problem (and reluctant to replace ECM).
Prius (2010-12) :: Getting Error Codes P0302 And P3191
I leave my car for 2 weeks without driving, and when I start the power, I have check engine light on and I drive to the dealer right away. Mechanic performs diagnostic test for engine misfire no engine miss found. The error code is P0302/P3191. The mechanic told me that I always run the car in very low on fuel, and it causes the 2nd cylinder misfile or not running when the fuel is very low. They suggest me always pump the gas when the fuel indicator has 2 bars left.
My question is that: How come the car cannot run in low fuel, low fuel doesn't mean no fuel, and it can damage the engine/cylinder?
Prius (2001-03) :: Would Not Start - Codes P3191 And P3101
My parents' Gen 1 2003 Prius, at 99,030 miles, wouldn't start, and I thought I'd share the problem description and the fix that worked for me, for others who see the same symptoms.

I have had no issues with this car of 120K miles until today, although my MPG has decreased to 35 MPG. The following lights came on with a loud beeping sound : Brake warning lights, malfunction indicator light, master warning light and the hybrid system warning light. These stayed on for 25 minutes and then went off. I drove 12 miles without any issues with all the lights and sounds beeping.

Bought a used Prius 2010 last december, Now the hybrid system is shut down and the assumption is that the hybrid battery is the culprit. No codes has been read out of the system but the car has passed 330 000 km so I guess that's very plausible. Have found a used battery from a 2009 prius who the local Toyota service facility says is compatible.

I turned on my car this morning to find myself faced with a variety of colored lights, including a little red car on a black bar on my MFD. Drove straight to the dealer and received word that the car was throwing codes P0A80 and P3023 and they recommend replacing the hybrid battery. I have a 2006, have done all the recommended maintenance at the dealer and it has about 133,000 miles on it.
View 19 RepliesPrius (2004-09) :: Hybrid System Isn't Working Properly
I have a 2004 bought in 2003. It recently logged its first 100k miles. My problem with it is not easy to describe. It is actually running more like a non-hybrid car. I can feel and tell the hybrid system is operational, and I can hear the electric motor whine when coasting, down, etc. However, I don't think it is running as it should or as it used to. It happened on highway while cruising about 70 mph. I hit the accelerator to pass someone, and I felt that something changed. I'll try to describe it: think of a half-clogged pipe. The water can barely gets past the obstruction. You keep applying pressure, and suddenly the clog dissolves under pressure, and water begins to flow freely, and the pressure goes down. So it felt like that. Now the accelerator pedal is lighter, car is faster to respond, yet I think something is wrong because the car isn't itself anymore.
I don't like problems like these because they are very difficult to diagnose, let alone fix. For a while I also have not heard the inverter pump whine after shutting the car off as I did in the past, but the last time I got out of the car today I heard it. I believe it was replaced five years ago after a collision with a Trailblazer wiped out half of the front end ( but with no power train damage). I checked the VIN for the inverter pump campaign, but my VIN was not in the range.
Right now my problem is that the car feels a lot faster than it has ever been. When I lift off the accelerator, it doesn't begin to coast as it used to. No warning light of any kind out of the ordinary is present on the dash, although it did have the red triangle on during start up with a message about the parking gear not being engaged properly. That warning went away after the change in performance occurred. Related?
I guess I will take it to the dealer to see if there are any codes stored. After my 30 mile commute this morning, no whining, buzzing or any kind of noise was present after I shut off the car and I got out. There is still no warning light.
Prius (2004-09) :: Getting Hybrid System Warning Light?
My wife just called and said this light came on. She said when it came on the car turned off its cruise control but kept running. Now she says it seems to be running fine but the light is coming on.
The car has around 110k miles and I just replaced the spark plugs, air filter and engine oil about 1k miles ago. What it could be? I'm going to have her pull codes at the auto parts store but she needs to do about 20-30 miles of driving today for work. Is it safe for her to do so?
Prius (2004-09) :: Hybrid System Warning Light And Running Out Of Gas
My hybrid system warning light came on last night in my 2005 Prius with about 89,000 miles. The car may have run out of gas (I wasn't driving). This car will only take about 8.5 gallons when the fuel light starts flashing. I started it this morning, light was still on, only 2 bars on battery, my car usually runs near the green, and the gas engine stalled after about 30 seconds. The gas indicator was flashing, so I added a 1/2 gallon I had at the house, and unplugged the 12v for about 10 minutes to clear the system. Upon restarting, fuel light was still flashing, but no hybrid warning light. Drove a few miles, filled up with gas, and drove another mile.
So my question, could running out of gas and driving a very short distance (light came on as my wife turned into our driveway), cause this warning light to come on? If so, will there be any lasting effects? Did unplugging the 12v battery clear the computer codes, or can I still get these read to learn more about what happened?
Prius (2004-09) :: Transaxle Disengaged Hybrid System Not Working
Car was deemed a total loss. I didn't think the damage was too bad and one of my friends at a bodyshop told me to go ahead and do a car buy back that I can't go wrong with a prius. My mother said $20 gas a week. So I did and gave my mom the difference. The Car drives going forward and in reverse just find. Besides the body damage I got underneath the car and I see a bent tie rod end and maybe a lower control arm. The thing is when I hop inside to move the car I notice the car reads transaxle disengaged and battery system won't charge in neutral.

I have a 2005 Prius with 135k miles. Yesterday the red exclamation light came on and also the hybrid system warning light. I shut the car off and it came on again. The third time the car started normally and it is driving normally today with no warnings. Does this sound like the 12 volt battery? It is original.
View 6 RepliesPrius (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) :: 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) :: Hybrid System Malfunction Indicator And Gas Engine Won't Stay On
I have a 2008 Prius with 106,000+ miles on it. It was running fine till 2 days ago, I didn't start it yesterday and today when i went to start it, I get the Hybrid System Malfunction light, along with check engine, the red triangle and TPMS light. The gas engine tries to start up, then 1 second later makes a grinding noise and turns off.
I am in Toronto and its cold, but not THAT cold yet. So I am doubtful its temperature related. I checked the fluids and they all seem to be sufficient (engine oil, radiator fluid, power steering fluid). I didn't notice any leaks under the vehicle either.
Prius (2004-09) :: Hybrid System Warning And Triangle Of Death Light On
A few days ago I was driving my 2005 Prius aggressively up a mountain road and all at once the hybrid system warning light, the triangle with the exclamation point, and the regenerative brake system warning lights came on.
After about 2 minutes parked, I restarted the car and the regenerative brake system warning light went off, but the other two were still on. I still drove it twenty miles home, over another substantial mountain gap (about 1000 ft up and another 1500 down), without any problems.
I checked the voltage of the 12v battery, which seemed to be on the low end, but OK. (I think the lowest reading was 11.9). There seemed also to be some turbulence in the inverter coolant reservoir.
I brought it into the electronic vehicle specialist in town here today, who pulled my codes and said that the hybrid battery was dead.
Prius (2004-09) :: 2008 - Hybrid System Warning Again Even After Replacing 12V Battery
I haven’t been on these boards very often since getting my used 2008 Prius because until now it has been very kind to me in terms of not needing mechanical repairs. Unfortunately that good streak seems to have come to an end. Driving home Monday evening (after ~30min freeway driving), my master system warning light came on, accompanied by the hybrid system warning light. I didn’t know what the latter was – had to look it up – but I immediately pulled to the shoulder. The car was driving normally, however. Since shops and dealers were closed for the evening, after much debate I ended up having the car towed to a family friend’s body shop; they were still there and had a scanner to check the error codes for me. My car was on the side of the freeway for well over an hour with hazard lights on and the dome light on and off occasionally as we got in and out of the car. By the time the tow truck arrived, I discovered that the 12V battery seemed dead; car wouldn’t boot up all the way, wouldn’t shift to neutral and didn’t want to power down – I had to try turning it off upwards of 10 times. I was surprised, given just the hazard light and limited dome light usage. We jumped it, got it in neutral and on the truck.
At the body shop, they said there were no error codes related to the hybrid battery; something about transmission that wasn’t clarified, and errors for low voltage on the 12V battery. With everything off, it measured 10-something V; something higher when turned on, but they believed the problem was a dead 12V battery. I was surprised that it would suddenly give out in the middle of driving, but we went ahead and replaced it the next day. I picked up the car Tues evening, and had no problems driving it home, to work the next morning. Unfortunately, during my drive home – strangely at almost exactly the same location as the first time – the same hybrid system warning light came back on. I’d driving about 70 miles with it off at this point before the reappearance. This time I didn’t pull over to the side (had enough of that before) but rather drove a few more miles to a parking lot where the car has now stayed overnight. I note that the car seemed to drive perfectly normally during that time; no loss of power.
