CEL code questions

Post by LegacyPunk »

So I found out that my car is throwing CEL codes for TPS, MAF, Knock Sensor, and some Idle thing.

Im pretty sure that the MAF code is being caused by my intake, no real problem, the code might have been old when I forgot to plug the MAF back in a long time ago.

The Idle thing is caused by my IC, so I guess it's ok.

But as for the TPS and Knock sensor Is this something I should check out? I probably should replace the knock sensor, but I dont know what the TPS is all about.

clear the codes....drive the car and see what comes up again. If you get repeat codes, you can be pretty sure they are accurate and you're having some sort of issue with that sensor.

Knock sensor detects engine knock... TPS (throttle position sensor) is on the throttle body and measures the position of the butterfly (open, closed etc).
