Prius (2001-03) :: Check Engine Light, Code P0000 Came On
I just recently purchased a 2001 Prius with 92,000 miles on it and the check engine like comes on frequently. I have a scangauge and I scan for codes and it comes up P0000. I clear the codes the light goes off and everything seems to be ok. I'm not even sure where to start "looking" for something to be wrong.

Check engine light is on and my code reader is giving me a P0000 code that is not listed in the Bentley's list of OBD II codes. My nose is telling me it's emissions related as the exhaust smells too rich. And the car is nearly stalling at idle. Suspect #1 is the MAF but the OBD II code does not support this.

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.

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.

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 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) :: Check Engine Light Came On - Pedal Position Code
I have a 2005 with 206,000 miles and the check engine light came on. The code reads "pedal position" but local mechanics are not knowledgeable to deal with electronics. The check engine light has been sporadic off and on so is this serious?

My check engine and red triangle light came on. I checked the code and it's a battery issue. The code is P0A7F. I called the dealer and they want me to bring the car in for a check. I have about 117,000 miles on the car. They have a service bulletin open. I would like to avoid paying large dollars for a new battery.

I bought my 2008 Prius 9-14 with 29,000 miles on it. (rebuilt title-big mistake I now know). I found out after I bought it that it had sat for 5 years before it was rebuilt) I figured it was a miracle the hybrid battery even worked.
I had no problems until 2-4-15 when check engine light was flashing and the car was shaking. The local mechanic said was the “clutch” (torque converter), took the engine and transmission out of the car to fix it ($2200). But he realized the mass air flow sensor (MAP) was not working even after he put a new one in so had me take the car to the Toyota dealer. The dealer found a cut in the engine harness and advised me to replace the harness which he said would cost $2800. The local mechanic saw the cut via my cell phone photo and offered to fix it for free which he did.
The next day check engine light comes on after driven 25 miles with code PO 301. (means misfires in cylinder one). The local mechanic switches cylinder 1 with 4, same code the next day, local mechanic switches the coils to the cylinders, still the next day the same code. He switched the fuel injectors. Same problem of cylinder 1 misfire. He cleaned the oil out of the intake manifold, did fuel injection cleaning, and cleaned gunk out of the fuel line. Car would drive good about 20 miles then same check engine light, same code, sometimes code PO300 (random multiple misfires).
