Electronic Ignition System: Notes

The electronic ignition system consists of ECM, CKP sensor, ignition coil, distributor, MAF sensor, TP sensor, ECT sensor, and Hall Effect sensor. See Figure .

Ignition system uses engine speed, engine load and throttle valve position signals to calculate ignition timing. Engine coolant temperature signal is used to correct ignition timing when engine is cold and to activate knock sensor circuit. See KNOCK SENSORS under IGNITION TIMING CONTROL  .
