Body throttle was dirty with oil. I cleaned it then put code ready on and these codes came up and I'm not sure if I just need to replace sensor or what to do next as car is not starting.

Do you

have the same problem?

Hi,

If you moved things with the throttle plate, it may require programming. What codes are now present? Let me know so I can help identify the issue and how we can go about diagnosing it.

Take care,

joe

I bought the traction control sensor and stablitrak sensor that goes below by the brake and changed the spark plugs and cleaned body throttle but still have these codes and my car will not start. So, where do I go from here? Thanks

Hi,

I noticed two crankshaft position sensors/Camshaft position sensor correlation codes. Both are specific to the exhaust cams on both sides of the engine. Does the engine sound normal when you are cranking it? If possible, record it cranking and upload it for me to hear.

Next, I need you to confirm the engine has an ignition spark.

here is a link that shows how to check:

Also, was the engine running prior to cleaning the throttle body? If it was, what products did you use to clean it?

Let me know.

Joe
