Code P2328 Description

The diagnostic trouble code P2328 indicates a problem with the ignition coil 'J' primary control circuit being higher than normal. This code typically appears in vehicles with a coil-on-plug ignition system, where each spark plug has its own ignition coil that is controlled by the vehicle's engine control module (ECM). In this case, 'J' refers to the specific ignition coil in question.
