DTC - P0300




DESCRIPTION
With the ignition switch in ON or START, voltage is applied to the ignition coil. A single high tension lead goes from the ignition coil to the distributor. Form the distributor, a high tension lead goes to each cylinder.
The ignition power transistor, controlled by the Engine Control Module (ECM), provides a switching circuit to ground for energizing the primary ignition coil. When the primary ignition coil is energized and deenergized, the secondary coil produces a high voltage spike through the distributor and across the attached spark plugs. The switching of the ignition power transistor also provides the ECM and Transaxle Control Module (TCM) with an RPM signal.
