Ignition Coil: 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 IGNITION COILS

a. Remove the ignition coil assembly.







b. Using an ohmmeter, measure the resistance between the positive (+) and negative (-) terminals.
If the resistance is not as specified, replace the ignition coil.







c. Using an ohmmeter, measure the resistance between the positive (+) and high-tension terminal.
If the resistance is not as specified, replace the ignition coil.
d. Reinstall the ignition coil assembly.
