Prius (2004-09) :: P3024 Code After Reconditioning Battery Pack
Jan 10, 2014
Back in November/December I discharge/charge-cycled each module in my battery pack 3+ times after replacing 3 bad modules. I didn't get to reassemble everything and drive the car until the holidays. On short trips around town, everything seemed okay, but on longer trips (limited data here, but say 40-45 miles) I got the red triangle and some other lights (see photo). I read the code as P3024 which from what I find means Battery Block 14 Becomes Weak. I can clear the code and the car is happy until the next trip...

About 1500 miles ago, I replaced a cell in the battery pack. Now the triangle of dead is back and the code is "replace battery pack" again.
I tested all the cells and here are the results.
(the previous one I replaced was 4.5 volts, very low and easy to find)

I posted earlier getting failure codes that might indicate something wrong with the battery pack. The codes were P3000, subcode 123, v0100 subcode 211/330. My independent mechanic said that I needed both the battery pack and the battery ECU replaced, based on these codes and the fact that they tested the hybrid pack under load.
At the same time, my auxiliary battery was low. You folks suggested replacing that first.
So I did. I have so far driven over 140 miles without the engine check light and triangle of death coming on again. But I do notice that the SOC screen shows my battery going into the green far more often and far more readily than I remember it doing so in the past. All it takes is a little downhill (say quarter to half a mile) and it will go into green--sometimes 100%.
I'm guess what I'm looking for is some sort of objective data that says my mechanics are right and not shining me on.

I 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?

My husband and I just bought a 2006 Accord Hybrid with 123,000 miles on it. The IMA and check engine lights came on two days later. I had the diagnostic check done on it and the code for battery pack deterioration came up. I read online where this code could be caused by the 12-volt battery going bad, and as it had the original battery in it, and the check on that showed it needed to be replaced, we did that. Two days later, the lights were on again. So we know we're going to have to replace the battery pack, which we're okay with, but what we want to know is whether the car will still run once that battery is completely shot. So far, it's still showing a good charge on it - whether that means anything, I don't know. Also, if it will run without the IMA component, will we be doing any damage to the car if we let it go for a few weeks?

Does PIP have two different batteries for each mode (EV and Hybrid) or is it the same battery?

I have two Prius's, a 2008 and a 2005. My 2005 with 129k miles on it is the one in question. Recently I got a check engine light with the code P0A80 and P3016. I purchased a pair of tested to be good cells from Ebay which finally arrived in the mail yesterday. Today I finally got around to installing it and everything was pretty self explanatory... One of 28 cells tested to have 6.24v in block six and all the others had between 7.98-8.00v all around. I went ahead and replaced the bad cell with the new one and put everything back together and now the car will not start.
Cliff notes: Replaced bad cell in main battery back due to CEL P0A80 and P3016.
Car will not start, only turns on...
Getting error message on the radio screen about the Park position is not correct and to park the car on a flat level ground with parking brakes and try again.
Have charged the 12v battery to make sure it has enough juice in it.

On more than one occasion, when I have gone in my garage at around 5 a.m., I hear a hum/buzz coming from the back end of my Prius. It has to come from the battery pack because the sound seems to come from under the back end of the car and is not as audible when I open the hatch.

I've got a 2006 Prius that was a model car--no problems at all--until it turned 4 years and 1 week old in April 2010. Then my aux battery died on 22 April, with just 31,583 miles on the car, and was replaced at Downtown Toyota in Oakland, CA. My dashboard lighted up after hours, and since my regular mechanic (Art's Automotive) was already closed for the evening, I had it towed to downtown Toyota. No huge deal, except for the cost of the battery/labor. The codes were: C2318, b1421, b1200, b1207, and b1271.
4 weeks later, on 22 May, I pulled into my driveway, and 4 lights came on: the MIL, the VSC, the yellow ! inside the circle, and the Hybrid System Failure icon on the MFD.

I have a 2006 with 188,000 miles. We replaced the hv battery at 155000 miles. the car has been getting lower mileage than usual, around 36 mpg, we usually get 43 to 45 on the trip to work and back. the red triangle appeared and all the other lights a couple days ago. Borrowed a code reader, not a scan gauge, and the code came up P0a85, and says the HV battery is overheating. I checked the 12v battery and it is low, at 11.7 volts. So I am replacing the 12v battery, should be here in a couple days, already replaced it once, about 4 or 5 years ago.

I'm getting the 14 blink code on my Hymotion LED indicating that my 12v battery is needing replacement. My question is that the car seems to run fine with the exception of my mileage is low. I'm ordering the Optima replacement. Can I still drive around for another week without worry?

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?

Had a company install fog lights on my replacement 2007 Prius I picked up after I totaled my 2008. When i went to pick the car up, the car wouldn't start. Showed the triangle of death and threw a code that the 12v was bad. Probably from having the car off and testing the fog lights continually - resulted in a drained battery. I picked up a brand new yellow top optima battery and thought this would resolve my issues. Nope, once the batter was replaced, the car wouldn't go into Drive or Reverse, only park or neutral. The current code is P0A0D. The shop is baffled. They removed all modified parts and still can't figure out the issue. They are currently replacing the interlock plug in hopes that this will resolve the issue.

I have a 2004 prius with p3000 sub 123 this is the only code. This happen after a replace a cell. Now I check every cell all of them are around 8 V.
P3000 subcode 123 is abnormal signal from the battery...

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!

Well, just replaced my HV battery, hooked everything up (I think) and tried to start it. ALL the caution lights came on and stayed on. This is the code that showed up on the reader. P0AE0. The battery was refurbished and I changed over my Computer module and the contact posts. Everything is tight, and I compared my pre-takedown pics to the post-repair work and it all looks correct.

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:

Was crushing around and received the red triangle, check engine, DSC, etc. pulled two codes from my scan gauge P3022 (bank 12 low) and PoA80 (replace hv battery). Car was in limp mode, engine running full time, battery gauge showed hv battery depleting.
After reviewing other stories online, seems as though I might be looking at a new battery. Car is 2006 with 112,000 miles.

We took our 05 Prius to the mountains on Sunday. Coming down the hill from Lake Tahoe the temp climbed to 98. Suddenly we got the red triangle warning and the Hybrid system warning light. The car ran fine and showed no symptoms of any problems. We took the car to the dealer Monday morning. They Read the code P0A82. They said the Battery cooling fan was not coming on and blamed the problem on dog hair. The warning light was off. The car ran fine going home with no warnings. My questions
1) Can/did the dealer reset the warning light?
2) Is there a way to verify that code P0A82 is a bad cooling fan.

My 2002 Toyota Prius keeps dying (triangle of death and OBD Code 3191) after running smoothly for a few seconds each time I start the engine. Clearing the DTC code allows restart. But the check engine light and triangle of death keep returning after a few seconds.
It has been doing all this since I recharged the 12V battery (which had been drained completely by a dome light left on for 3 days). Initial attempts to recharge the 12V battery were causing current spikes at charger, and (relay?) clicking sound under the hood. So I disconnected positive battery cable and charged the battery in isolation, then reconnected it to the vehicle after charging was complete.
When I reconnected the recharged 12V battery the vehicle (honking horn) alarm went off. But that stopped when I unlocked door with key. It may not be related, but I'm also hearing a fan-like sound (under driver seat) when ignition key is in run position. I don't recall hearing that sound in the past.

Code says P1121 Accelerator Pedal Position Sensor Range/Performance Problem. I heard that was wrong and its really coolant control valve? The battery drains fast and the can runs like crap. Would this code be doing that to the car?
