Ignition Coil: Testing and Inspection
IGNITION COIL INSPECTIONIgnition coil inspection
1. Perform the spark test and identify the malfunctioning cylinder.
2. Replace the ignition coil of the malfunctioning cylinder with that of a normal cylinder, and reperform the spark test.
- If the spark is not normal due to a malfunctioning ignition coil, replace that ignition coil.
- It is unlikely that all four ignition coils fail to operate properly. To prevent replacing a normal component, perform the above procedure, identify the malfunctioning ignition coil, and replace it.
Ignition coil with built-in igniter inspection
1. Disconnect the ignition coil connector.
2. Measure the resistance between each terminal on the ignition coil connector using an analog circuit tester.
- If the measurement corresponds to the table, replace the ignition coil.
