Corvette c8 p0340 p0341

Hello everyone,

I'm experiencing an issue with my C8. Occasionally, after starting the engine, the check engine light comes on, and after performing diagnose, two error codes appear: P0340 and P0341. Both of these codes are related to the camshaft position sensor. I've already replaced the sensor and ECM and battery, but it hasn't resolved the problem.

It's been over a year since this problem began. The engine starts normally every time, and there is no indication that anything is wrong. All sensor connections seems to be ok. What sould I check next ?

Look up the OEM Service manual with an AcDelco TDS subscription for your particular model and follow the diagnostic steps for your codes.

I've checked all electrical connections with service manual procedures and everything is seems to be ok.
