2003 Cadillac CTS Repair Question
Cadillac CTS Engine Problem
Your going to have to have all the computers in your car scanned for codes and get the exact code numbers you have.Its not going to be a easy diagnoses most likely.
Thanks I'll get back to you with the codes.
Alright make sure you have it scaqanned with more then just a basic diyer scan tool that can read all the computers and not just the engine and transmission ones.
Hey sorry to get back so late to you but here are the codes here goes.
You have a ton of throttle postion coedes and throttle circuit codes plus some codes i cant find that exist for that car.Lets start with the code P0221.Do you have a multimeter to do some testing?
I don't but my mechanic may,is
There an electrical problem as well like the engine harness wire? Do you think I need a new throttle body cause I change the throttle position sensor already and I had the computer relearn it to calibrate it.
With doing some testing cant really answer those questions.
When get the mutimeter where should start testing and what should I be looking for?
How did you replace the tps when its part of the throttle body?You will also need a scan tool that reads livew data to monitor the tps readings for the first part of the test.
Sorry I meant I replaced the throttle pedal sensor.
