Prius (2004-09) :: P0A80 Error Codes Appeared, Still Pending
I recently replaced my engine water pump at 164,000 miles on my 2007 Prius, the car sat for 3 weeks while waiting to gather needed parts, i.e., water pump, coolant and Airlift system for adding coolant fluid. After installing the new water pump the car ran rough for 5-10 minutes upon initial crank (parked for 3-weeks). I took a 20 minute test drive around the neighborhood that evening, outside temperature around 65 degrees F, and car ran fine. SOC looked ok, bars moving between Blue and Green, everything appeared normal.
The next morning, I backed out of my driveway and the Red Triangle of Death appeared on the dash so I parked the car.
That evening I hooked up OBDII ELM327 scanner using Engine Link and picked up 2 separate P0A80 error codes, 1 of them was pending. I disconnected the Aux battery for 3-5 mins to clear the error's, Red Triangle of Death was cleared, then drove the Prius for 20 minutes with no errors or alarms. SOC seemed to be normal. OBDII ELM327 scanner showed the HV batteries were charging at same level, 16.8V and Aux battery was registering at 14.0 Volts.
The next morning, after 20 minutes of driving the Red Triangle of Death appeared, and shortly after I experienced loss of power, with sporadic engine idle and interior traction battery fan was on. Luckily I had made it to work and was able to pull into a vacant parking lot.
I did notice that around the time the Red Triangle of death came on this morning the SOC dropped quickly to 1 Purple bar and was slow to charge then shortly after came the loss of power and sporadic engine idle followed by interior battery fan.

I am getting P0355 error code and potential misfire codes on all cylinders. Engine light and VSC stays on now. Idle is unstable and power is a little jerky at times. I bought a Denso direct ignition coil to replace, however, Cyl 5 looks difficult to access.

Bunch of warning lights appeared and the dealer said it's code P0a80 and they recommend replacing the battery. I'd like to try to fix this myself and would like to hear your thoughts...
Plan is to check the traction battery for corrosion and use a voltmeter to test the cells and replace if needed. Prius 2004, 158,000.
Lexus RX 2010-15 :: P0138 And C1241 Codes With Error Messages On RX350
My wife suddenly had error messages today, Check AWD System, check engine, traction. Carista reports P0138 O2 sensor high circuit voltage bank 1 sensor 2and also C1241 ABS low battery positive voltage. I get the O2 sensor or wires could be bad, but the C1241 could be expensive ECU. Think both could happen at same time or just a thrown code? Reset turned warnings off but Carista reports permanent for P0138.

I just bought a used 2008 Prius. I had my Prius inspected after buying it, and the error code C1378 appeared, which I have discerned refers to the Skid Control ECU.
There is apparently a recall for this part in 2010-2014 models, however as a 2008 I don't think I apply.

Prius (2004-09) :: ABS And Brake Light Came On - No Error Codes
I have a 2005 Toyota Prius with about 150K miles on it. After work one night i hit a pothole and my ABS and BRAKE lights came on. I took it to a garage and they could t find anything wrong with it so they reset the light. It came back on about a week later (no potholdes this time) and i took it back. They hooked it up again this time it said there was an issue with the computer coding. So i took it to a Toyota dealership. They hooked it up to all their scanners and could find nothing wrong with my vehicle. They recalibrated the sensor and the light went off. Now a week later it is back on again. Brakes work fine and we get no error codes.

The red triangle warning on my dash recently came on so I am taking it to the nearest dealer on Monday. I think all of this is covered under recalls/warranty. Am I right?

Last week I was on a dive trip and my RX remained parked outside for a week. As I was returning home and I was merging on the highway my CEL appeared; I used my scanner and the code was p2195, which I cleared. My RX was driven for about 5 minutes before merging onto the highway.
On my way home I needed to stop for gas, I filled up and them merged onto the highway and the CEL came on again. I used the scanner and the same code p2195- which I cleared.
I completed my drive home, and have only been doing short city driving since then an no CEL's.

Prius (2004-09) :: CEL With Error Codes P0117 And P1150 Diagnosed
I just bought my 2006 Toyota Prius about a year ago in 2009. About a month or two ago, the check engine light came on and stayed on along with a big red triangular warning light.
I brought the vehicle into my local Toyota dealership so they can diagnose it.They told me that they had 3 or 4 different "codes" coming from the machine when getting the signals from the check engine light. All the codes were related to the cooling system. They said that they felt that there was "debris" clogging the pathway for the coolant flow throughout the engine. They had recommended a "coolant flush" for the hybrid side as well as the mechanical side.
So I had them perform the coolant flushes. After leaving the dealership that 1st time, the check engine light came back on the next day. I called the same dealership and explained it to them. They asked me to bring it in again.
SO I brought it to them a 2nd time. They diagnosed it again. They told me they came up with 2 of the SAME "codes" and 1 that was different, but ALL the codes were STILL related to the cooling system. They explained to me that something was preventing the clear flow of coolant throughout the engine. And since the thermostat was the only major obstacle, they recommended that I replace it. Well, I did. And after I left the dealership that 2nd time, I was praying that this was the last of my Prius issues !
The check engine light came back on the next day. The service person invited me back and did not charge me this time because it was the same issue. I told them that I am not in the business of randomly changing parts on my car unless I am absolutely sure I know exactly what the problem is. HOWEVER, this time they kept my vehicle for a good week or two. Running it through various diagnostics tests overnight here and there.
They finally came out and said that they feel that I have a coolant system leak coming from my engine and that I need to replace my head gasket which is responsible for sealing the engine.
During my 1st visit, the codes were P0117 and P1150
During the 2nd and 3rd visits , in addition to those, there was one additional one that came up that I will post as soon as I find it !
Prius (2004-09) :: Error Codes P1121 And P3000 - Not Enough Coolant
So I received the P1121 and took it to the dealer. They told me I also had a P3000. I called another dealer and they said the P3000 could be caused by the P1121 not giving it enough coolant. So I brought it back to the house, bought the valve listed in the forums, and I spent all day changing that + the coolant. I drained the coolant and between the reservoir and the radiator cap itself I refilled about 4 QT, and I saw that my inverter coolant was just below the low line, so I filled it up to the full line. Afterwards, I tried to get the coolant to flow, and it seems like I won't flow. The check engine light immediately came back on and the car said, "Problem." So I immediately shut it off and let it set for a few days. How do I get it so that the coolant starts flowing again. I haven't seen any of the levels move whatsoever on the radiator.

Had a shutdown with error codes P0078 and P0092 on the scan gauge. Reset the codes with a scangauge and the car goes drives fine. This has not repeated for a couple of days but I was wondering where to see a list of Gen2 codes so that I can better understand what happened.

My son drives our old 2005 Prius with over 300000 miles on it. He had a front end accident a few years ago, and, after body repair and a straightened frame, the car has been running pretty well, although the mpgs have been in the low 30s. This may be the result of his "lead foot." He recently saw the check engine light and the car shows the codes P2601 and P1116.
