Bought my 2010 Prius with some issues, most of which are now fixed.
The remaining issue is the mentioned A/C error code: B1498 A/C Communication malfunction (A/C inverter local)
What part this is, and the OEM part number? Where is it located in the car?
Previous owner claimed it was some error with the A/C Control unit.
Against my better judgement I picked up the ex wifes 2001 Prius after the "mechanic" she took it to ran the HV battery dead. I picked up two Gen II batteries and built me a good battery. Then I cleaned all the corrosion off the harness and terminals and put the HV battery back in. The engine spins but dies. There are no engine codes but under the HV ECU cattegory I get a {P3106 communication malfunction, engine > HV}. I had a spare HV ECU and swapped it and get the same code. Spare engine ECU and the same code also. Not sure where to go from here. How to check voltages at the ECM ?
View 10 RepliesSo got this P0A93 code when I was driving on the highway about 65mph, scared to me death when big yellow warning light came on so I returned home and turn the car back on after 30 mins the code and all the warning lights were gone I checked under the hood felt the pump everything was good. I just got done 90k maintance on the car from dealer. So my question is that could be computer error or it could be water pump malfunction? On warranty manual the warranty for inverter with converter covers under 100k so dealer should be able to cover the water pump if it's broken? I driven the car today again at normal temperature and full blast AC on, then again no engine check light on and warning light no message.
View 4 RepliesWhat would make the OBD II not read the code that is set on my truck. It says "Communication Error..." Fuse 41 grants power to the Diagnostics port and the cigarette lighter. The cigarette lighter is working. Any other reasons I can look at?
View 3 RepliesI have a 2004 Prius with 80k miles. Always has been a workhorse. Recently had a bad cell in the HV battery. Battery rebuilt with new cell and now works great.
Now it runs about 20 miles and then displays dash lights of red triangle and small exclamation (brake?) and VSC.
I took it to Advance Auto and their scanner reads C1310 'Malfunction in HV system'.
I actually replaced the entire HV battery again with the battery from my friend's car, and the 12V battery too, but no luck. Same error.
If i disconnect the 12v battery for a while, it will clear the code and the car runs fine for about 20 miles and then dash lights come on again.
Car runs perfectly, over 50mpg even with the dash lit up. What that code is?
HV battery problem. I have Prius from 2007. In The car occur na error U0293 - Lost communication with Hv ecu.
View 9 RepliesThis is a 2008 Prius with no check engine light or other operational issues. The car runs fine. When doing a health check with a Techstream scanner (new toy), it shows the code U0073 along with U0123, 124, 126, and 293. Need to further diagnose what may be wrong?
View 7 RepliesI had to change my fog light fuse tonight, no reason found for that. However, I somehow triggered an error code, P01C1. I managed to reset it, but what this code means?
View 6 Replies 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.
Recently, when I ever press the brake while the head light or three AC is on, an error message appear for a few seconds ark malfunction.
View 6 RepliesI have a Toyota Prius (2010), and the car has run for about 2800000 kilometers. One day when a was driving my Prius the engine light suddenly get on. So I went to a car car mechanic, he checked the car and told me there was an error code (error code: P0401, exhaust problem (exhaust recirculation flow).
So I bought a liquid that I put in the gas tank, the liquid would clean the exhaust pipe, but the engine light was still on. The engine light is usually on at least 2 weeks, then disappear for about 2 days and come back in two weeks…The car is driving normally without any problems.
The 2005 Avalon has 48K miles and it's been running well without any issues, until today.
Driving in city traffic, max speed is about 30 ml/h, The "Check Engine" light and the "VSC (Vehicle Slip Control) Off" lights came on. I did stop the engine, restarted after couple of minutes and the same lights stayed on. The car ran just fine, no noticeable difference in performance.
With the OBDCOM reader, the Avalon has this code:
P0351 232
P0351 Ignition coil A primary/secondary circuit malfunction
That seems to indicate a malfunction for cylinder A, or #1, ignition coil that has nothing to do with the "VSC" AFAIK. Is this a misread by OBDCOM reader, or the Avalon is confused?
The code had been reset via the OBDCOM reader, the car runs fine, neither of the lights come on now. Should I do something about coil A, or just wait until the code comes back?
Truck wont start idm communication error all the fuses are good and the relay seams good I switched it out with another relay 340,000 miles how do I know if its the IDM r not... I'm sure the idm is not cheap...
View 2 RepliesSo 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.
So I swapped an R motor into my 20th anniversary GTi. It idles fine as soon as I rev it and the idle comes back down it starts breaking up and I get a code for exhaust flap no communication. Of course, there is no communication since I don't have one. Is there a way to code this out or to trick the ECU to make it think its there? As soon as i clear the code the car runs fine, even if I just turn the car off and back on, it runs fine.
View 24 RepliesI have an 04 V6, yesterday it was perfectly fine...last night we had torrential down pours, high winds and standing water... not sure if any of that matters, but this morning I went to take the kids to school and my "BRAKE" light, the ABS light, and the exhaust lights were all on. Took it to a local shop and had them check for codes. They said it was U0121... lost communication with ABS module. What should I do? I drove it a couple of miles back to the house and again earlier this evening to see if anything felt different, but all seems the same.
View 2 RepliesAs the title says it all I have a 2010 Malibu LS with roughly 88k on it and just noticed that the CEL light came on last weekend. On Monday the light went ahead but it came back on this morning. Took it to Autozone and the error code was P0172, Fuel System Too Rich, Bank 1. I noticed this happened last weekend after putting in some gas at QT. The Autozone guy recommended some fuel injector cleaner as a starting point and recommended using pure gasoline (premium).
View 12 RepliesMy baby won't run throwing PO1668 IDM PCM Communication Problem. It threw the CPS code first I changed the CPS and it now has the other codes. I'm stuck how do I test the idm all the fuses are good and the relay is good I believe I switched with another one... 341,000 miles I love this truck .....
View 2 RepliesCEL, Triangle Displayed for the second time, Engine goes to READY, ICE starts and shuts down when I assume adequate charging is reached. However, OBD2 code thrown is P1636. Drives very well from what I can tell. But she just reported the CEL & Triangle went on again and she feels it is driving rough, like it is struggling.
View 19 RepliesMy check engine light has come on twice now and I'm getting a p0505 code, idle air control malfunction. It seems as though there could be a couple causes for this. All my hoses seem tight, so the cheap fix seems out of the question. What could the other causes be, and more importantly, about how much for a shop to fix it. I have a 2006 with 155,000 miles on it.
