Ignition Coil: Testing and Inspection
Ignition Coil Test
Coil 1 fires cylinders 1 and 4, coil 2 fires cylinders 2 and 5, and coil 3 fires cylinders 3 and 6. Each coil tower is labeled with the number of the
corresponding cylinder.
Ignition Coil Electrical Connector
1. Disconnect the electrical connector from the coil pack.
2. Measure the primary resistance of each coil. At the coil, connect an ohmmeter between the B+ pin and the pin corresponding to the cylinders in
question. Resistance on the primary side of each coil should be 0.53 - 0.65 ohm at 21° to 27° C (70° to 80° F). A coil that has not been allowed to
cool off, would result in inaccurate measurement results. Replace the coil if resistance is not within tolerance.
Checking Ignition Coil Secondary Resistance
3. Remove ignition cables from the secondary towers of the coil. Measure the secondary resistance of the coil between the towers of each individual
coil. Secondary resistance should be 10,900 to 14,700 ohms. Replace the coil if resistance is not within tolerance.
