Code P1367 Chevrolet Description
When a Chevrolet vehicle triggers diagnostic code P1367, it indicates there is a problem with ignition control cylinder 7 not switching after activation. This code specifically concerns the engine ignition system, which is responsible for generating the spark needed to ignite the air-fuel mixture in the combustion chamber. In this case, cylinder 7 is not receiving the correct signal to ignite, which can lead to misfires, poor engine performance, and potential long-term damage if not resolved.
