High Idle *FIXED* and alternate part found for CTS

[Holmes]

My car has been idling at 1100-1600 rpms even when warm. Cleaned

and checked the IAC and it seems to be working fine. Noticed that my

coolant temp sensor didn't resemble the ones I've seen on other cars.

As I'm looking through some online parts catalogs, I run across this part

that looks just like one that's in the place my CTS should be.

They call it an "air charge temp. sensor". I guess it's functionally the

same as a coolant temp. sensor just with a different name. The fact

that it has a harness already attached is a bonus. I had already bought

the CTS so I replaced it with that. No more high idle. This other sensor

worked fine up until a few days ago. Looks like it had been on the car

for many years. I would have bought another if I didn't already have

the other CTS in hand.

 

So, this might be a good solution if you want to replace your CTS and

the harness at the same time because of excessive corrosion.

what kind of car do you have? Anyone know if this would work on an EA82T?

Yes, I believe that's what he is talking about, an EA82T or at least an EA82 SPFI
