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?
View 3 RepliesI have an 07 Prius which I bought used in 2011 and which has been fine (except for some A/C work last year) but got the 'triangle of death' this morning and having towed it to my regular shop, they tell me the code (they couldn't give me the number) simply said 'replace hybrid battery'... the car has 102,605 on the clock.
View 9 RepliesI have a 2007 toyota prius. The car drives, but pulsates. The Check engine light and triangle of death are on. Diagnostic test says "replace hybrid battery pack", but wouldn't the car not even start if the bat pack were dead? What it could be? perhaps a bad cell or two? a bad ecu?
View 19 RepliesMy check engine light came on, I took the car to my usual mechanic, and he said the codes returned indicated that two cells in the batter were bad. (I just called to get the codes, but he's out of the office for about 30 minutes on a test drive...)
View 8 Repliesi have a 2006 with almost 200k miles. Got the red triangle, check engine light, and the red car at the top of the MFD. I ran the codes and got P3000. Does this sound like traction battery failure? The car still turns on and ICE still cycles off and on.
View 19 RepliesI have a 2007 Prius with 107k miles. Last July it had a minor drivers side front end collision. Last November it had the hybrid battery replaced. I believe all this is unrelated just putting it out there for information.
I am currently having the red triangle pop up intermittently. When it does a "problem" message will display on the MFD. This seems to occur most often after a long downhill or when the Energy display is showing the hybrid battery is nearly full.
The hybrid battery seems to be functioning normal and the car is driving normal and has expected fuel economy. I do have a headlight that cuts out occasionally but no other noticeable electrical problems. I do not have a diagnostic device to get the codes.
I had my Prius check out and gave me these trouble codes couples battery's low he has a red triangle ....
P0A78
P3000
P0A80
P03014
P0315
The battery's rating 13.5 volts. Will always trouble codes go away after replacing the battery I added inverter to it because it was it was dying after 50 miles per hour then it slowed down??
Have replaced dead cells on wife's HV battery over a month ago. Threw this P0a80 code today and will barely move. She idles into dealership and they say it's the battery, really!
View 2 RepliesI have a 2008 Prius. I noticed that a large red triangle displayed briefly on the left when I started my car the other day. I know all the other smaller icons light up briefly but I don't remember the large red triangle lighting up. It and all the other icons go off after a second or two. Then the next time I started the car there was no red triangle. Then maybe the 3rd time I started the car, the large red triangle did again appear briefly. I took my car to my Toyota dealership but the tech said that is normal and means a door must be open, but that cannot be correct. I make sure all doors are closed and the "Open door" icon is not showing. I have already been through the water coolant inverter pump disaster so I admit I am a little paranoid about any funny things showing on my dash.
View 16 RepliesTested and replaced 2 bad battery cells in my 2007 Prius... Got everything put back together and now all dash lights are on and engine won't start... When i try to shift into drive or reverse it goes directly into park... I tested the battery without removing the safety key and the inside terminals are at 220 volts and the outside terminals are at 0 volts as shown by photo... Maybe due to a fuse somewhere?
View 19 Replieswell I saw one other thread on this topic but no resolution. I replaced the hybrid battery like the codes told me too on my 2003 prius and it now drives great but as soon as it start it shows a problem and the red triangle stays on. No check engine light, no codes, no driving issues just a red triangle. How to diagnose a red triangle when there are no codes.
View 16 RepliesMy concern: The hybrid battery, or the monitor really, has never, ever, not once, shown an all-bars charge. It is almost always at one bar down, and will drop below that but never goes above. My brother has a Gen I and his battery shows all bars from time to time. Not mine.
View 6 RepliesI have a 2005 prius with 84,000 miles. The car is running fine but the main red triangle light came on. I took it to toyota and they said I needed a new hybrid battery.
View 10 RepliesSomething in my Gen II 2006 Prius is causing a type of overheating condition in the hybrid system. The fault/error codes coming up are P3190 and P3191. If I turn the car off for 30 minutes and restart it, it runs fine for a period of time (but usually not more than a week).
I first noticed the problem a couple of months ago during my 45 mile (mostly highway) commute. While driving on the highway, I noticed that the Prius wouldn't accelerate when I stepped on the gas pedal. A couple of minutes later, my dash warning lights come on and the car started slowing down (no response to the gas pedal at this point). For a minute or so, I was able to change gears (reverse or drive) and move a little in either direction but the transmission stops responding altogether very quickly.
Dash lights that light up
Hybrid system error symbol lit up and I noticed that the hybrid battery charge level was at one purple bar.
The first time it happened, I had my car towed to the nearest Toyota dealership. The flatbed tow truck driver (to my surprise) was able to start the Prius and back it into a spot at the dealership. Some of the dash lights were no longer lit.
The dealer couldn't find anything wrong with the car except for the fact that my water pump was leaking. They replaced the water pump, cleared the error codes and drove the car around for about 45 minutes but couldn't reproduce the problem. I drove my car home.
note: this dealership replaced my hybrid battery and 'computer' (I'm sure it has a specific part name - I don't have the info) right before my warranty ran out over a year ago. I didn't have any warning lights lit up on the dash at the time but I told the master mechanic working on my car that it didn't have much power going to the wheels when I put it in reverse (I couldn't back into my driveway). After the hybrid battery and computer were replaced, I had no issues with backing into my driveway.
The same issue happened a week later. I turned the car off for 20-30 minutes, started the car and noticed that the bulk of the dash warning lights turned off so I drove it home. I took it to my local mechanic the following day. He cleaned the intake manifold, changed the spark plugs, cleared the P3190 and P3191 codes indicating that they were generic codes indicating a misfire and said that it was now running fine.
A week later the same thing happened. I did some research and brought the car back to my local mechanic and asked him to change the transmission fluid & to use the Toyota ATF WS fluid. He changed the transmission fluid (and noted that it was dirty), cleared the codes and I brought the car home. I unfortunately didn't get a sample.
We had a power failure that night so I plugged my pond aerator into the cigarette lighter to keep my koi alive and less than 2 hours later I came out to find the pondmaster ap-20 (20 watt) air pump (blows bubbles through 1/2" tubing) wasn't running and my car had shut off with the dash warning lights illuminated. I have run this little aerator for 4 days on a single tank of gas without issues in the past.
I replaced my hybrid battery of my NHW10 a year ago. now recently it shows the warning triangle. Once it went off after a long drive but now its permanent. is there a way to Diagnose what is the cause of this? If its a Hybrid battery issue, will it go off if i replace the bad cells?
View 3 RepliesMy 2007 Prius has been with me for 3 months now. I am really happy with its performance, especially its fuel consumption rate.
I would like to check the state of the hybrid battery and maintenance it if necessary. How could I get this done?
I tried to turn on my car this morning, but the "Ready" sign didn't go on. The whole display is black. "Check Engine" sign blinked briefly. Battery display shows the battery is "green". Everything else works - cd/radio/bluetooth, etc. As I tried to start it, the screen showed that the engine briefly charged the Prius battery, then it was all quite. I tried to wait and restart a few times, but still the display was all black and no "ready" sign. I WAS able to still move the car, but I didn't chance to drive it out of the garage. I just had it serviced (oil/fluid change). Small battery was replaced in July.
View 19 RepliesIs there anyway to charge a couple of batt cells by running the car.
Just replaced 2 packs and there voltage is 2-3 volts lower than the rest of the batt packs? the ones replaced are at 14.5 to 15 where the others are at 17-18 volts.
I found a decent deal on a 2nd gen prius. But I am going to need to repair the battery. I have already known that I can test and only repair the needed cells (since I looked into the situation when I was buying mine a year ago). Looking at the forums and saw there were a couple of chargers being recommended by the users; such as the supermate DC6 or the Hitec 44151 Quad X4.
I will likely want to charge 8 cells at time at least, as I would ideally like to get the car fixed in a couple of weeks.
2006 Prius with 130k miles. I'm thinking that my HV battery has slowly deteriorated to the point where it's causing drivability issues, and now needs to be replaced.
The main symptoms I'm experiencing are rapid charge/discharge according to the MFD and significant loss of power once the battery has discharged to one bar. I realize the latter is "normal," but the problem is that I'm seeing one bar frequently now. Hill climbs that my car used to do with no problem and would drain the SOC to 2-3 bars now cause the battery to drain to 1 bar about half-way up and then loss of speed from 65 mph to 45 mph by the time I reach the top. Descending hills, it's not unusual to see the SOC go from 2 bars to 7-8 bars within 30 seconds or so.
I'm not seeing any error lights, and my (cheap) code reader does not report any logged DTCs.
This seems to be a slow degradation of battery performance, rather than an outright failure. I first noticed that the battery would charge/discharge a little quicker than it had been at about 90k miles. At 99k (before the warranty ended) I took it into the dealer and they tested the HV battery. Block voltages ranged from 16.59 to 16.68 V and resistances ranged from 0.025 to 0.026 ohms. Based on this, they said that the battery was fine, and sent me on my way. Since then, the problem has just gotten worse and worse, though.
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.
