Ignition Cable: Testing and Inspection

ON-VEHICLE INSPECTION

NOTE: "Cold" and "Hot" in these sentences express the temperature of the coils and sensors themselves. "Cold" is from -10 °C (14 °F) to 50 °C (122 °F) and "Hot" is from 50 °C (122 °F) to 100 °C (212 °F).

INSPECT HIGH-TENSION CORDS




a. Remove the No.3 timing belt cover.
b. Remove the throttle body gasket.
c. Disconnect the high-tension cord set from the spark plugs.
Disconnect the high-tension cords at the rubber boot. DO NOT pull on the cords.

NOTE: Pulling on or bending the cords may damage the conductor inside.




d. Disconnect the high-tension cord set from the ignition coils.
1. Using a screwdriver, lift up the lock claw and disconnect the holder from the ignition coils.
2. Disconnect the high-tension cord at the grommet. DO NOT pull on the cord.

NOTE:
- Pulling on or bending the cords may damage the conductor inside.
- Do not wipe any of the oil from the grommet after the high-tension cord is disconnected.




e. Using an ohmmeter, measure the resistance.

Maximum resistance: 25 kohms per cord

If the resistance is greater than the maximum, check the terminals. If necessary, replace the high-tension cord.




f. Reconnect the high-tension cord set to the ignition coils.
1. Assemble the holder and grommet.
2. Align the spline of the ignition coil with the spline of the holder, and push in the cord.




NOTE: Check that the holder is correctly installed to the grommet as shown in the illustration.

3. Check that the lock claw of the holder is engaged by lightly pulling the holder.

g. Reconnect the high-tension cord set to the spark plugs.
h. Reinstall the throttle body gasket.
i. Reinstall the No.3 timing belt cover.
