IGNITION SYSTEM NOTE: These engines use a fixed ignition timing system. Basic ignition timing is not adjustable. All spark advance is determined by the Powertrain Control Module (PCM) .This engine uses a distributor, crankshaft sensor and ignition coil. Basic ignition timing is not adjustable. The system's main components are the distributor, distributor pickup, camshaft signal, crankshaft signal and ignition coil.The crankshaft position sensor and camshaft position sensor are hall effect devices. The camshaft position sensor and crankshaft position sensor generate pulses that are inputs to the PCM. The PCM determines crankshaft position from these sensors. The PCM calculates injector sequence and ignition timing from crankshaft position. For a description of both sensors, refer to Camshaft Position Sensor and Crankshaft Position Sensor.
IGNITION INTERLOCK All vehicles equipped with automatic transaxles have an interlock system. The system prevents shifting the vehicle out of Park unless the ignition lock cylinder is in the OFF, RUN or START position. In addition, the operator cannot rotate the key to the lock position unless the shifter is in the Park position. On vehicles equipped with floor shift refer to the - Transaxle for Automatic Transmission Shifter/Ignition Interlock.
