Prius (2004-09) :: Warning Lights Appeared With Error Code P0a80
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.
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.
Prius (2004-09) :: 2006 - Got Error Codes P0A80 / P3019 / P3000?
Yesterday I got the "red triangle" and check engine light along with these 3 codes:
P0A80 - replace hybrid battery pack
P3019 - battery block 9 becomes weak
P3000 - battery control system
In April of this year I have the entire battery replaced, in September I got the triangle again and one cell was replaced under warranty. My warranty is good through April 2016, however I'm afraid that this new code P3000 is going to be something not included in my warranty.
What could potentially be wrong? This is a 2006 Prius with approximately 208,000 miles. I'm not sure this is worth it anymore especially if I have to keep putting in more money.
Prius (2004-09) :: Code P0A80 - HV Failures
My 2006 is doing some weird things. I have gone through a couple of HV failures and each time if I got the P0A80 code there was always an additional code telling me what was wrong. Not this time. Some times the battery will sit there while it shows that it is being charged and not take a charge. i.e. not come up off the pink bars, Sometimes it will charge all the way up to green and then fall off dramatically This is really strange because it is not showing any other code other than a crank cam sensor. The 12 volt battery seems to be ok.

Was driving home from school yesterday and my 2005 Prius turned the check engine light on and the red triangle light. Plugged into the scan tool it read: P0a80. I have a hybrid battery ordered. It should be delivered on Tuesday. How long can I get out of this failing battery before the car is undriveable? The Prius is my only vehicle and I don't have a problem with installing the battery, I just I'm wondering if the car will just drop dead on me before the battery gets here? The car appears to be driving normally with no loss of performance or MPG.

2005 Prius. I just don't want to jump ahead to replace the hybrid batteries right away. Can I still drive the car, some place people say it is okay to drive then eventually it would get weird...

I had a 12v battery issue that I see common. 12V battery does not crank car. Jump car and works fine for a few days. I had this issue and it went away. Dealer said replace 12v battery, or just carry my charger pack with and use that unless it gets worse.
Jump ahead 2 months. I drive 50 miles each way to work 5 days a week. No issues. Yesterday, after my car sitting all day, I am backing out of driveway and get the red triangle. Code was P0A80. I looked it up. I cleared the code and was going to dealer if it came back. Today, after driving 50 miles into work, no issues, I get the red triangle. Code P3021. Fan started running back there too
My question : Would replacing the 12v battery useful for this issue?
Prius (2004-09) :: Replaced Dead Cells On HV Battery - Code P0A80
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 RepliesPrius (2004-09) :: Warning Triangle Came On And Scanner Show P0A80 Code
My Prius has started throwing the code P0A80, it all happened after I went away for work and left the car in storage for 15 days, during that time I left the OBD scanner plugged in and it drained the 12v battery, a quick jump start and it was back up and running.
While I was backing it out of the driveway the warning triangle came on and the MFD said "problem" the scanner showed the P0A80 code. I thought that was odd, but maybe related to the flat 12v battery and self discharge of the traction battery so I reset the code, it drove normally to the shops. When I restarted it and started to drive it threw the same code again.
I then installed techstream on my laptop to try and get some more in depth answers but was having trouble getting that running on Windows 8. So overnight I disconnected the 12v battery and would try again in the morning.
I got techstream working and connected it up to the car, connected the 12v and started it. While I was configuring techstream to graph the pack voltages I noticed something odd, the engine was being loaded and unloaded in 2 second cycles, and at the same time the inverter was whining as it does this. I was thinking maybe it's doing some sort of charge and measure cycle since the ECU's have lost any pack data due to the power loss of the 12v battery?
It ran like this for 20 mins or so and the engine stopped, techstream showed pretty normal cell voltages, I couldn't see any wild differences between the cells.
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?

Prius (2004-09) :: Replaced 2 Modules In Hybrid Battery - Code P0A80
I have 2005 Prius with 300k miles. I started throwing P0A80 code. I removed the battery and checked all the modules and found 2 of low voltage, ordered them from Ebay and replaced them. I placed the battery back in the car and started the car but got P0A80 code again. I purchased the grid charger from Hybrid Automotive and connected it according to their instructions for 24 hours. I drove a car but got the red triangle again and P0A80 code again. I removed the battery again and tested the voltage of all the modules and these are the readings:

My 2007 Prius with 176k had the warning lights on the dash. I finally got the code read and it is the P0A80 code. The 12 volt battery seems good, it is about a year and a half old or so. That was the only code.

Its a 2009 Prius with about 75K miles on it. I have scangauge on the dash as well as mini-VCI. It is setting PO456 code time after time. I reset it, but it comes back in about 50 mils of driving. Its not the gas cap, I turn it until it clicks every time. Something is wrong with evaporative emissions system, which I wouldn't care about, except it might mask some other fault code that is more serious, as it keeps check eng. light on all the time.

Installed Rebuilt Hybrid Battery AND New 12v Yesterday. Worked great until just now. Got the cool Red Triangle and VSC... hooked up to that Cool code machine and got the P0AAC (Hybrid Battery Pack Air Temperature Sensor "A" Circuit).
What is this exactly and what should I do? If it's a simple fix, I'm sure I can do it with my dad ... after all, I did take and reinstall the battery myself. Also, is it going to hurt my car if I drive on it with this issue?

Prius (2004-09) :: 2005 - Getting P0505 Error Code
I have a 2005 Prius with almost 244,000 mile and about a week and a half ago the check engine light came on. I went to an Advanced Auto and had them read the code for me, which came back with a P0505 error code. I have read several things on web that this code is a Idle Air Controller related.
I also have read that this could be to a loose or bad PCV valve, an air leak in the vacuum lines, throttle motor shaft might be binding, or a failed engine ECM.
The car runs and idle just fine, no stalling or a rough idling. The only problem that is obvious is that when the car is warm and I come to a stop or put in park, the motor will not shut off.
Which one of these would cause this to happen? Or could this be due to a MAF sensor that needs cleaned or replaced?
