Hi there, I am Cam. Can I get your first name please?Can you tell me the code numbers pleasE?
That would be fine Carl. Save the link and reply back when you get them.
Ok so do they happen at the same time?Is there any chaffed wiring in the underwood fuse block or around the PCM? If all that is good then Ia m thinking its a problem inside the Powertrain Control Module (PCM). It reads and controls both and with both operating normally, its the device checking afterwards that is causing the issue, and thats the PCM.
If your certain the wiring is all good then, and the areas I suggested are good then I think its the next place to look.
OK, let me know what you find.
