P0354 Chevrolet Description
The ignition system on the vehicle uses individual ignition coils for each cylinder. The Powertrain Control Module (PCM
) controls each ignition coil operation. The PCM
sends a ON/OFF signal to energize the ignition coil to create a spark at the spark plug when a spark is required at the cylinder.
