GMC P1364 Code Description
The GMC P1364 code indicates a problem with ignition control cylinder 4 not switching after activation. In simple terms, this means the engine control module (ECM) is not receiving the expected signal from the ignition control module for cylinder 4. This can lead to issues with ignition timing, fuel delivery, and overall engine performance. The ignition control cylinder is responsible for firing the spark plug at the right moment to ignite the air-fuel mixture in the combustion chamber. When this process doesn’t work correctly, it can result in poor engine performance, increased fuel consumption, and potential engine damage over time.
