Ignition Coil: Testing and Inspection
INSPECTION OF IGNITION COIL (3S-FE)1. INSPECT PRIMARY COIL RESISTANCE.
- Using an ohmmeter, measure the resistance between positive (+) and negative (-) terminals.
Primary coil resistance (Cold): 0.38 - 0.46 ohms
- If the resistance is not as specified, replace the ignition coil.
2. INSPECT SECONDARY COIL RESISTANCE.
- Using an ohmmeter, measure the resistance between the positive (+) and high-tension terminals.
Secondary coil resistance (Cold): 7.7 - 10.4 k-ohms
- If the resistance is not as specified, replace the ignition coil.
