Prius (Gen 2) :: 2008 With Red Triangle Error And Code P0A37
Mar 8, 2014
I have a Toyota prius 2008 with 130,000 miles. I kept getting red triangle sign, the car will slow down and will need to pull over, shut it down and restart. I went to the dealer. First they diagnosed 12V battery issue, so we got that replaced. The red triangle sign kept coming, so we went to the dealer again, they replaced transmission fluid. They said it was low on transmission fluid. The red triangle sign kept coming. So we went to the dealer again. They said it is transaxle internal problem. The diagnostic code is P0A37. I have a couple questions. In California, what is the warranty for Transaxle problem. In some posts I saw 180,000 miles, 10 years. The dealer said they called Toyota and Toyota does not cover the repair. It is a costly repair. Second , is this code really requires Transaxle replacement.

I recently purchased a second-hand Prius T4 (2007 model) and I noticed that the red triangle exclamation was showing on the dashboard. Initially, my local mechanic found a P3000 error code and a B1801 error code.
I ran techstream on it just last night and the main errors that came out were:
Current codes:
Srs airbag B1801 - open circuit in driver side circuit
Air conditioner B1421
Transmission control - C2318
History codes:
HV battery - POA84
I also have just found out that this car was in a major collision in 2012. The air bag light is constantly on, along with the red triangle exclamation, on the dashboard. The fuses for the battery fan kit, horn, and air bag needed replacing (I think all three but definitely two of these).

Two issues are bugging my 04 Gen 2. The check engine light came on a while back, and the code I'm getting when I have it checked is 505, and I'm told it's the idle control system.But then I've been told that the Prius doesn't have an idle control system. At first it came on intermittently, and I noticed that when it was on the ICE did not turn off when sitting at a light or at low speeds, etc. It made sense to me that it might be something with the idle control, but I'm not an engine person. Now the light is on all the time. I haven't had the time to get to the dealer yet, but I suspect that's about to change, due to the next issue:
When making sharp left turns, I'm getting a very brief red triangle/beep/warning on the MFD that says "problem!". Sometimes it is so fast I don't even see the MFD warning.

I have a trouble with my 2008 prius; red triangle engine light is coming and when i try to push the gas pedal it feels like it's freeze, the car does not accelerate so I have to stop.
After i turn it off and start again it drives ok, but a triangle is still there and there is error code POA90 ( two different scanners show same code with two descriptions; the first is "MOTOR PERFORMANCE"; the second describe it as "14-volt power module system voltage high").
Specially it happens when i drive up the hill and push the gas pedal harder. What it can be? I took the car to the Toyota dealer; they looked for 8 hours and find nothing; i can't do it again as the car do not have a warranty and the dealer charge for hours.

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 night I was driving home in my 2002 Prius, and the 'triangle of death' as you call it, went on. I got off the #405 and parked for 10 minutes while I read the manual which said get to a dealer as soon as possible. I started it back up and the engine seemed to be fine but the 'triangle of death' was still there, so I decided to continue to drive but stayed in the right lane.
I must have gone another 20 miles when I suddenly lost engine power, the headlights and dashboard were fine, and hazard lights worked fine. I was able to get to a safe place and towed the car home. Along with the 'triangle of death', the check engine light (little red icon) was on but I didn't get the 'Main Engine' error message.

I successfully replaced the HV battery on my own and it was so easy even this girl to do it! I drove the car about 300 miles when I got the triangle of death warning light again yesterday. I took my 2002 Prius to the dealer to read the codes but how to borrow a scanner (or whatever) from Autozone and do it myself.

I have these two codes:
P0A37 - Generator temperature sensor circuit range/performance
P0A2B - Drive motor "A" temperature sensor circuit range/performance

I was able to pull codes this evening ( no subcodes).
The codes are as follows:
P3000, Battery Control System Malfunction
P3030, Battery Voltage Detective Line Snapped
Will the P3030 cause a P3000 to pop up since it appears I have one of the 19 voltage detect lines corroded or broken?
Once I fix this issue, is there a chance that the P3000 will disappear?
I was just getting the triangle and the Main Battery error on the MFD up until yesterday. Yesterday, the ! with the car came on (Hybrid system) on the MFD. I did not check any codes until today. Car will currently not start at all.
Aux battery voltage is confirmed to be 12.3 volts via the MFD in the diagnostic mode so it's good to go.
No one around has a scan tool that will also pull the subcodes.

I have an 04 Prius that recently had the HV battery rebuilt with replacement of a couple of cells. It now is showing dash lights of Red Triangle, Small Exclamation, and VSC. Error codes are coming up on techstream v9 as :
P3000 curr
P0A84 hist
C1310 curr
C1311 curr
(all 4 of the above have asterixes by them )
B1421 curr (no asterix)
The car is running perfectly and seems to be fine.

I'm rebuilding the traction battery on my 2006 Gen II Prius. When completed, I'd like to erase any "error codes" that should be erased (I don't even know where these might be), and turn off the red triangle of death, the VSC light, the (!) idiot light, the engine check light and the maintenance required light.

Stopped at ATM when heard a thump under seat and all the above appeared on control panel. Waiting on computer code reader to test vehicle. Any clues to what all this means. Vehicle 2006 with 101K. Recent service as scheduled with coolant and inverter coolant and belt replacement done. No other issues to date with vehicle.

have a 07 prius with 113k miles. It recently displayed the red triangle with code p0aa6 sub code 612.
I took apart the battery and nothing looked corroded, then on the inside of the bus bar i found a small amount of corrosion. After testing the cells i found 2 modules that were leaking voltage.
Since I had everything open I figured I might as well test to see if any cells were on there way out. The static voltages were pretty close around 7.8v, there were a couple modules that were .3v apart that I'm doing more testing on. I load tested each module with 1a, is 1 amp enough for a load test? I have a 100a load tester but figured that was way too much. They were all ok under load test, dropping about .6v and returning to original voltage within a few minutes.
Then I decided to check capacity on the bad cells, they were about 500mah, got to 1000mah after 1 discharge/charge cycle. I tested the capacity on a cell I thought was good and so far it discharged about 1050mah until it reached 6v, this was from 7.77v. I'm giving it some time to rest to see if it goes back up a bit and then I'll discharge some more till it stays at 6v. Even if I get a little bit more in it will be way under the 6500mah it should have or even the 3500mah that I've read is acceptable.
Since all of the modules have parameters that are pretty close I'm thinking the capacity will be pretty close as well.

So of course it has to happen 3 weeks after my warranty expires. My CEL comes on and I have it read and the result is P0440. I find out that my wife has a habit of topping off the gas tank and so I am thinking that she has probably ruined the charcoal canister. It is something easy to replace?
I have an 06 limited edition... Yes, she will not be topping off any gas tank anymore.

I have a 2008 Sports Trac, with a 4.0 SOHC engine ... 165k miles. Last week my check engine (CE) light came on and the code is P0401 ... too little flow on the EGR system. I first tried cleaning the existing valve - but CE light still came on. So I replaced the old EGR valve, cleaned the SS tube from the exhaust manifold back to the EGR valve and the CE light is still on. I have not driven the truck since I replaced with the new valve ... only fired her up in the garage. Is this something that could possibly clear up given a couple of miles?

I just bought a F150 with 103,000 on it. The engine is a 4.6. I get a P0605 code every now and then which doesnt effect performance. I erase the code and it doesnt appear again for maybe another 100 miles.
I suspect a loose connector but not sure. Looked up the code and it reads PCM READ ONLY MEMORY (ROM) ERROR. My question is what does the PCM operate? And wheres a good place to start troubleshooting?

Is it safe to drive my '02 with the triangle on the dash? I've tried to get rid of it, throttle body cleaned, MAF cleaned, battery seems good (13v, no load). What else can I do to try and get rid of it? BTW, '02 Prius, 183K mi. It runs good, cycles on and off normally (motor to battery, etc.). The code clears it self after sitting about a week w/ occasional starts, then I drive it for about 50-70 miles and the light comes back on...

Working on a 2010 with 156k miles that threw a P0A80 on two separate occasions. Once before the 12v battery was changed, then the day after the 12v change. Decided to change the HV traction battery today with one from a wrecked 2014 with 56k miles.
After changing the HV batt I started getting the yellow triangle with no code associated with in. I would clear the code and drive the car a few minutes and then the triangle "check hybrid system" would appear.

I picked up a 2004 Prius with 150k. It has no check engine light and no codes with a scangauge. I hooked it up to a mini-vci with techstream and found the following: P3009-526, C1310 and B1421. The car will only start if you reset codes, then after a few minutes of running the red triangle comes back.

I have around 68k miles on my 2009 Prius and just got a CEL, the Red Triangle with an exclamation point, an intermittently occurring VSC light, and an intermittently occurring yellow circle with an exclamation point on the upper dash display. I also have a car shaped icon with an exclamation point on my main display (ICE?). My scan tool shows P0093 as the only code.

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.
