Ignition Coil: Testing and Inspection

Ignition Coil Electrical Connections:

1. Turn the ignition switch OFF.


2. Disconnect the 4-P connector and ignition coil wire.

Coil Terminal Labeling:

3. Using an ohmmeter, measure resistance between the terminals. Replace the coil if the resistance is not within specifications.


NOTE: Resistance will vary with the coil temperature; specifications are at 20°C (68°F)


Primary Winding Resistance
(Between the A and B terminals): 0.6 - 0.8 Ohms

Secondary Winding Resistance
(Between the A and secondary winding terminals): 14 - 22 kOhms

4. Check for continuity between the A and C terminals. Replace the coil if there is no continuity.
