Prius (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 (2010-12) :: Engine Off And Key Not Detecting Error?
I have a 2010 prius. I put in a new stereo system and as part of the process had to disconnect and reconnect the battery. The car drives and the stereo works. However, when I turn the car off and step out of the car with the key fob and shut the door there is one beep in the car and three outside the car and the display reads "key not detected" and it won't let me lock the car with the key fob. It appears to think the car is still running when I leave but it is definitely off. The "key not detected" error message then stays on and will not go off until I go back into the car.
Does the car or key fob need to go through a reset? Is it something I can do myself or do I need to bring it into Toyota? I've tried searching for a fix online and checked the manual and even contacted Toyota and haven't found anything that has worked.
Prius (2004-09) :: Check Engine Light On - Code P1117
Finally got my first check engine light at 108k miles. Pulled my codes with an OBD reader from Oreilley auto parts.
P1117 is Coolant temperature sensor circuit, low for coolant heat storage system.
Coolant heat storage tank outlet temperature sensor.
Short in temperature sensor circuit
ECM
I just wanted to make sure I had the right piece before I buy it. I did check the levels of my coolant and they are perfect, so I'm sure the sensor must be bad. I believe it'll just be a water temp sensor. I just want to make sure it's this, and not some random sensor I'm missing.
Prius (2004-09) :: Code P3030, Check Engine Light Came On
we have a Prius from 2004.
We have had problems with the starter battery. This is because the car is so rarely driven. So to fix this I have charged the battery several times. But have not disconnected the battery cables before. I don't know if thats the reason why we have problems though. But you can suspect that.
One morning when we should drive the car we saw that the "check engine light" came up on the dashboard. And other warnings also.
I bought an OBD scanner and hooked it up. P3030..
So I took the hybrid battery out of the car and cleaned all poles and connections. I measured each battery cell to approx 7,6 V.
I also bought a new starter battery. Now, I have put all together again. But P3030 is still the case.
Is it possible to measure the voltages from the busbar module by measure on the contact to the ECU? I have tried that but don't get stable results. The voltages goes up and down all time..
My last hope is that a wire between battery busbar and ECU is broken. But I couldn't recognize that when I had the battery out of the car.
Prius (2004-09) :: Check Engine Light Came On With Code P1116
My check engine light came on with a p1116 on my 2008 with 138k. I replaced the sensor, but the p1116 came back. How to fix. I'm going to replace the coolant today, I read somewhere there might be a clog.

About once a week my check engine light comes on. The code is P1121, which is about coolant valve sticking. In about one or one and a half days it times out and i dont get the warning light for another week or so. Do you think I should have something done right away or wait and see what happens?
View 1 RepliesPrius (2004-09) :: Check Engine Light Came On - Code PA080
I was driving when the engine light came on. I always carry my OBD II reader in case this happens. Upon reading the code it gave a reading of PA080. Since I have a spare battery at home and have fixed 3 others for friends and family I was not to worried.
I arrived home and took out the battery to measure the voltages. To my surprise all voltages were good. I figure maybe it was corrosion so i tool the module bus harnesses and cleaned both the copper pieces and screws. After reinstalling all i took it out for a drive and after 20 minutes the check engine light came on. Bummer!
Went back home and disconnected the original HV battery and installed the spare HV battery and took the vehicle for a ride. All seemed good when the engine light came on again after 20 min. Removed that battery and all voltages were also good.
Troubleshooting began first by checking the 12V battery with an ohmmeter and it read 12.4 volts. Thinking this was good I jumped at checking the HV
battery including switching the CPU to no avail. In the process I left the HV battery disconnected which gave me codes indicating loss of communication with CPU scaring me even more.
Finally decided to take a break and look around on here and google when I found a better way to test for a week 12V battery. This test required me to let the car sit, turn lights on and press power button twice. If I got a red triangle and message indicating that the transmission sensor was in an abnormal state a weak 12v battery was to blame. So i went put to the car and tried it to my surprise I got the red triangle with transmission message.
So I went to OReilly and got a 12V battery for $170. Came home installed it and took Prius out for a drive. After 30 minutes no Check Engine Light. So far all good. I drove it to work and back home without an issue. This car has 141k miles and 12V battery was approx 5 years old.
Prius (Gen 3) :: 2013 - ODB II Scanner Caused Check Hybrid System Error
I purchased a Bluetooth ODB II scanner off of Amazon which had all positive reviews, plugged it into my 2013 Prius this AM and the car immediately started beeping with the "Check Hybrid System Stop The Vehicle In A Safe Place" error. The car is functioning just fine but I'm concerned.. Is this normal? Should I have not plugged it in while the engine was on? I want to see if I can clear the error but I'm afraid to plug the module in again...

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.

I took a one owner 2009 with 100,00 miles for a pre-inspection today. All came back in fairly good shape however the mechanic ( an independent shop ) found this error code P1455. I took the car back to the dealer & said I was interested in the car if they looked into whether the gas tank would need to be replaced. The parts manager gave my husband and I a long speech about how they checked the car before it was traded in and never found this code. He explained that the code has to appear twice for the " check engine light " to come on. He told us he would take the car for a test drive himself & put it thru another diagnostic test to see if he could get another error reading. He will be getting back to us tomorrow. The dealer also said we could discuss in writing a timeline for them to repair it if the check engine light come on & ultimately a repair is needed.

I'm going to look at an 05 prius tomorrow and the seller said there is a check engine code. If I had a list with description I can at least know if it could be serious. He said the car drives fine and everything works. Not sure if there is a difference in codes for engine versus the hybrid part of the car .
View 1 RepliesPrius (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?
