code P0507 high idle

[Brian D]

Hi Guys ,



I am having an issue with my 03 . She idle's way to high. Put a code reader on it and had code P0507 IAC. Took it off , cleaned it ,couple of drops lube. Put it back on . no change, Replaced it with a new one, also no change. Cannot seem to find a vacuum leak either......



Any thoughts.



Thank

Brian D

i had the same problem. try replacing the you tps. get the one that is for a door dr if you go through advance. it should be the same color as the one you take off.

i did the same thing as you replace the iac vavle, erg vavle. pvc erg regular. no still the same problem so replace the tps and that should fix it.

Don't know if I'd diagnose by guessing and changing parts. A faulty TPS usually throws P0121-123 codes.

If you have a VOM check the TPS voltage. It should be bellow 1vdc. KOEO......



Also check for the TB blade seating. May have dirty build up. Clean the MAF at the same time.

Also wouldn't hurt to clean the throttle body and MAF sensor.



EDIT-Wow Eddie, you beat me by one minute. Telepathic? :grin:
