Ignition Coil: Testing and Inspection

Ignition Coil Test:

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

Ignition Coil Resistance Test:

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 68 °F (20°C).

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.
