Dtc P0120


My car keeps showing the Malfunction indicator light and when I scan it the DTC is P0120. That is a throtle position engine malfunction. As a fool I went and spend 160 bucks on the Throtle position sensor wich did not fix the problem.

I have set everything according to the service manual but I think I may be missing something because the dam light keeps popping on.

I would like to get my car inspected but it will not pass with the DTC ligh on.

Does anyone have a hint on what to do? Can you direct me to someone that knows?

No SAFC
Man... I had to disconnect the SAFC because I could not get the car to run right.

So I only have the HKS VPC. And.... I can get the car to run strong but the light keeps coming back on after about 3 or 4 stops and starts of the engine.

Thank you, Lico
