Hi All,

My check engine light is so close to finally being off, and hopefully my rough idle woes will be gone! Woohoo! I have one last code that I am receiving for the IAT sensor (P0112). Seems like it is related to the voltage which a test with a multimeter confirmed that is in-fact there is not voltage reading on the wires. For fun, I did try a new sensor as mine looked a bit corroded, still same issue. Wondering what the next steps would be to confirm whether it would be the wiring or the PCM and the repair steps for either.

Thanks in advanced!

 

Just wondering if anyone could provide some insight on this? It's the only code thats being thrown at the moment for me. Seems to be causing a rough idle for me.

 

Disconnect the IAT connector, and the PCM connector containing the IAT wiring. Check the wiring for continuity/resistance.
