Code P2322 2017 Chevrolet Silverado Description
The P2322 diagnostic trouble code (DTC) for a 2017 Chevrolet Silverado indicates an issue with the Ignition Coil 8 Control Circuit High Voltage. This means that the powertrain control module (PCM) has detected a higher than normal voltage in the control circuit for ignition coil 8. The ignition coil is responsible for converting the low voltage from the battery into the high voltage needed to create a spark in the spark plugs, which ignites the air-fuel mixture in the engine cylinders. When the control circuit voltage is too high, it can lead to misfires, rough idling, and overall poor engine performance.
