Corolla Wagon 18L DOHC Ignition Coil Component Information
Ignition Coil: Testing and Inspection
Inspect Primary Coil Resistance
- Using an ohmmeter, measure the resistance between positive (+) and negative (-) terminals.
Primary coil resistance (Cold): 1.1 - 1.7 ohms
- If the resistance is not as specified, replace the ignition coil.
Inspect Secondary Coil Resistance
- Using an ohmmeter, measure the resistance between the positive (+) and high-tension terminals.
Secondary coil resistance (Cold): 9 - 15 k ohms
- If the resistance is not as specified, replace the ignition coil.
