2001 Hyundai Elantra Repair Question
Asked on June 21, 2012
Do I have possible IAC valve problem?
Engine revving high. When I disconnect the IAC valve, engine stops idling high but it is still rough. When I put the IAC back, it revs up high again. Already checked for vacuum leaks and didn't find any. How do I bench test the IAC valve? Could this be the problem?
Thanks.
Thanks.

Try cleaning the iac valve and the port it goes in with some carb spray.Also do you have any codes did you check for them before unplugging the iac?

Yes. It wasn't sticking, but I cleaned it anyways. I had 1 TPS code - P0121. I also checked the value and everything is in spec on TPS. How would I check the values between the terminals on the IAC?

Did you remove the iac when you cleaned it?Also if your getting a tps code we need to follow the trouble tree for it.Does the tps code come right back after clearing it?
