Prius (2001-03) :: Triangle / Check Engine Light Popped On When Driving - Code P3006
I have a 2001 Prius with 210,000 miles. The inverter and traction battery were replaced last year. I started getting triangle and check engine lights about a month ago and the scan tool read p3191 p3006 p0300. The car would barely start in the mornings and the dash lights would be dim. I replaced the 12v aux battery today and all the symptoms went away. Driving home the triangle/check engine light popped on again and I stopped at Orielly's to use their scan tool. It now only reads P3006. I called a local mechanic who suggested to drive it a bit and clear the codes because the battery needed to equalize. Is this true?

Yesterday on my morning commute, the red triangle, brake light and check engine light popped up on my dashboard. After about 10 more minutes of driving I lost a lot of my driving power. The system screen showed that there was no brake regenerating happening. I could hear the battery fan going behind me pretty loud.

I've got a 2009 Prius with 67k miles on it. The car has a salvage title, but has given me over 20k+ worry free miles. The past few days the car has been acting a bit odd (i'm not sure if these are related or not but I figured I'd just throw it out there as well).... The right front headlight has been on the fritz as well as the wireless door opener has been working sparsely (sometime it wont lock, sometimes it will). I just ran the test to make sure teh 12V battery was okay, and all of the voltages came back in the "normal" range.

I bought an 01 Prius with 148k miles. It had code P3125 which mean bad inverter. I replaced the inverter with one from a junk yard with 81k miles. As soon as I was done the car started right up, and I didnt get electrocuted!
Right after the car started I got codes P3115 P3001 and P 3191. I cleared them out and turned off the car for a min.
When I started the car again I got codes P3030 and P3001.
This car has an extensive service history, It has a new Cat and exhaust, a new accessory and HV traction battery that are less than 8 months old. Crank position sensor is new. fuel tank is new.
What could be causing the P3030 and the P3001?
Prius (Gen 1) :: Code P3125 After INV Coolant Pump Replacement
I picked up a 2003 that had a bad AUX battery and P3130 code. Just FYI, aside from the battery it drives fine. Kicks the Warning light after about 15 miles but since the battery was bad it kept getting reset. Replaced the battery with a nice optima conversion.
Took out the inverter coolant pump, tested the circuit (good), tested the pump (bad). Replaced with a new one from dealer. Set up the bleeder tubes and massaged the lines till the new pump stopped SCREAMING at me. Added probably 2 qts of TLLC total. Bleeder tubes never had enough pressure to push fluid back up to reservoir but got solid 2 inches of fluid with no bubbles. Topped of the coolant. Went for a drive around the block, made it halfway (about 28mph) before the light kicked in and the motor seemed to bog down. Limped back home and read the 3125 Code. Code reader does not give me sub codes.

Prius (2001-03) :: P3100, P3125 Error Code Came On
My Wife was driving our 2001 Prius and got the big triangle and the car went into limp mode.
The Codes were P3100 (info code 196) and P3125 (info code 325)
P3100/196 = Internal Error - Generator CPU Malfunction
3125/325 - Inverter Internal Short. - Generator Inverter Fin - Inverter Internal short
Clear the codes and the car runs fine, but the problem will eventually resurface.
The dealer wanted tor replace both the converter/inverter and HV ECU.
I purchased replacement converter/inverter from Ebay and inverter coolant pump (new) and installed.
Problem eventually resurfaced. I purchased replacement HV ECU from ebay and installed.
Engine would not start (does not attempt to even turn over), but was not throwing any codes. I had this same symptom with a third HV ECU as well. The part numbers on the HV ECU were exact matches.
Prius (2001-03) :: Shuddering Transmission - Code P3125 And P3120?
Working on a 2002 prius with 153k miles. bought it with a "Bad transmission" diagnosed by toyota dealer. Got I home and did a quick check but there were no codes. I drove it about 50 feet into my garage where it would shudder badly while being driven which from my experience sounds like a bad MG2 motor. Drained the oil and thought hhmmm th oil does not smell bad and neither did it look burned. Proceeded to pull the mg2 but found it looked brand new, no burned spots or any such thing. SO I put it back together and think its a bad invertor. put on a different invertor that I have lying in my garage that I "think" is good and start the car. get code p3125 and p3120 and still have the bad shuddering when i try to drive it..Is there any way to test it further before I pull the trans and put a new trans back in?

My 2002 Prius died the other day. Getting DTC P3125 when I ran it through my scanner, but I don't have an advanced enough one to get the sub-codes. It's got 215,000 Miles on it, so I would expect something major to be happening at this point.
Here's a detailed description of what happened --- I was driving down the freeway the other day and started noticing my car was sputtering a little bit and losing a slight amount of power. I pulled over to a restaurant to say hi to a friend; when I came back out I started the car and the check engine and battery lights came on. About 10 more miles down the freeway the car started heavily limping and barely was able to get me off the freeway, then the car completely died. When I would start it back up it would die in about 5 to 10 seconds. The 12v auxiliary battery, not the main hybrid battery, had completely died.
I figured it might have been just a dead old battery that needed replacement so I put in another new one. It ran amazingly for about five minutes around the parking lot, then the same thing happened again. It completely died just like before.
The 12v battery isn't getting re-supplied with the juice it needs. Something's wrong in there.
The either the inverter is shot, it's just overheating due to a faulty coolant pump, or the MG2 generator isn't putting juice back into the 12v system.
I checked the fluid reservoir. It looks like it's flowing, but there is a few bubbles floating to the top of the fluid. Is that normal?
Prius (2001-03) :: 2002 - P3125 Sub Code 325 With No Start / Inverter Failing
Pulling into parking lot and the triangle and exclamation light appear on dash. Drive about an additional hundred feet with what felt like lower power and no noises.
- Check 12V after about an hour and it reads 12.4 volts.
- Read codes and get P3125 sub code 325.
- Temperatures and HV battery numbers all looked good.
- Clear codes and immediately code comes back with no start, nothing. Did this many times.
This code and sub code lead to the inverter failing. Being that there was no noise as a MG2 stator failure this also leads to an inverter failure right as the MG1 motor starts the engine? Inverter pump still running good as it was recently replaced along with ATX fluid. Within the last two weeks two HV modules have been replaced.

So I was driving home last night and went to accelerate and it felt like something slipped, lost acceleration and the red triangle of doom popped up. car worked fine for about 15 seconds then just the electric battery was being used.
Drove about 100 feet then got no response out of the throttle for anything. Had to push it the rest of the way home.
Towed it to dealership, been there for 3 hours and they still haven't found the point of failure. Once they give me diagnostic codes I will post them.
Prius (Gen 1) :: Red Triangle After Having Car Parked In Extreme Rain / Heat Pop Up
I have had the red triangle after having the car parked in extreme rain/heat pop up when I start the vehicle 3 times in about 6 months. The first 3 times I did not have Techstream so I just cleared the codes, but the third time I finally read it and had those 3 codes, the first two I assume being most important. I clear the codes each time I see them and they stay off 1-2 months. About 140k miles on car. New 12V battery. No driveability issues. Car still gets decent 60 mpg in summer, 50 in winter. P3000 P3009 B2799

Yesterday I parked on a very slight slope (the front sat maybe 1 half to 1 foot higher than the rear) for a few hours. It was the end of my carport. When returned to move it forward and park, it was dead. So I put a charger on it and got it started but then the red triangle warning light was on saying that there was a problem with the parking system.

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 (2010-12) :: Check Engine And Red Triangle Light Came On - Code P0A7F
My check engine and red triangle light came on. I checked the code and it's a battery issue. The code is P0A7F. I called the dealer and they want me to bring the car in for a check.
I'm afraid it will lead to me replacing the battery. I have about 117,000 miles on the car. They have a service bulletin open on this code but I may have exceeded the 100,000 mile limit.
If I do need to replace the battery are there any improvements I can make in this area?
Prius (2004-09) :: Check Engine Light / Red Triangle And Code P0A80
I'm guessing that I need to repair or replace the HV battery. But I'm not sure.
Today I drove for about 20 minutes with no issue. 10 minutes later, I got back in the car to drive again. This time, after about 20 seconds into the drive, a string of dash lights came on; Red triangle, VSC, Check engine.
The VSC light went away. But the red triangle and check engine light are still on. So, I had the trouble codes pulled by a mechanic, and the code P0A80 was returned along with a statement reading 'replace hybrid battery'.
Should I take this at face value? Or look for something else first?
