Honda Civic Ignition System: coils, ignition timing and more

Honda Civic 1992-1995 EG and EJ

IGNITION TIMING CONTROL

ECM or ECU has complete control of ignition timing. Timing is controlled in response to signals from various sensors. Input signals from TDC, CRANK and CYL, throttle angle, coolant temperature, and MAP sensors are all used by ECM to determine optimum ignition timing control.

Battery voltage is supplied through ignition switch to ignition coil and Ignition Control Module (ICM). ECM triggers ICM based upon signals from TDC, CRANK and/or CYL and other sensors. High voltage from ignition coil is distributed to each spark plug by distributor.

DISTRIBUTOR REMOVAL AND INSTALLATION

Disconnect 2-pin and 8-pin connectors from distributor. Disconnect spark plug wires and coil wire from distributor cap. Remove distributor hold-down bolts. Remove distributor from cylinder head. To install, coat NEW "O" ring with engine oil and put into place. To complete installation, reverse removal procedure. Set timing to specification.

IGNITION COIL REMOVAL AND INSTALLATION

Ensure ignition switch is in OFF position. Remove distributor cap, cap seal and leak cover. Remove 2 screws to disconnect Black/Yellow and White/Blue wires from coil primary terminals. Remove 2 mounting screws. Slide ignition coil out of distributor housing.

IGNITION TIMING

1. Timing marks are on timing belt cover and crankshaft pulley. Start and warm engine to normal operating temperature (cooling fan comes on). Connect timing light.
2. Ignition timing check connector is located behind passenger-side kick panel. See Fig. 5 . Connect jumper wire between Brown and Black wire terminals.
3. Check ignition timing and adjust to specification, if necessary. To adjust, loosen distributor hold-down bolts and turn distributor housing counterclockwise to advance or clockwise to retard timing. Align pointer with Red timing mark.
4. Tighten distributor hold-down bolts to 16 ft. lbs. (22 N.m). Recheck timing. Remove jumper wire from ignition timing check connector.
