so ive tried my ecu in two different cars and it keeps showing a iacv code. the ecu is a p28 installed with s300. in smanager it gives me the option of disabling the iacv, but then im guessing my idle will be bad. i cant actually test this out yet because my car isnt up and running. before i had a edelbrock 75mm tb with the adapter plate, but i just switched over to a throttle body that retains the iacv function and now im afraid i still wont be able to use it....

has anyone replaced the iacv components or have any info on them?

 

I've cleaned an IACV with brake parts cleaner before. Unbolt the IACV from your manifold and disconnect the hoses. clean the insides with brake parts cleaner, dry it out and then reassemble. I hope this works...

 

I have replaced the IACV transistor and a few resistors that got burnt up when I put my tuning ecu into a customer's car that had the IACV and IAT plug mixed up.

It would throw the IACV code in every single car I put it in afterwords. There is a 3 pin driver and a few green resistors that get burnt up when these go bad.

This fixed my problem completely and I have been using the ecu ever since without a problem.

 

Hello, need help in locating the iacv transistor on my Ecu, (p2m y01) any ideas? because after doing all those test I I still Got code 14

 

can you provide pictures of the 3 pin driver and location on the ecu? and the transistors as well, Thanks in advance
