Code P2302 Mitsubishi Description

The P2302 Mitsubishi diagnostic trouble code (DTC) indicates a problem with the ignition coil 1 secondary circuit, specifically that there is insufficient ionization occurring. The ignition coil is responsible for converting the low voltage of the battery into the high voltage needed to create a spark in the spark plugs. When the secondary circuit of the ignition coil is not ionizing properly, it can lead to misfires, rough idling, and poor engine performance.
