Ignition Coil: Testing and Inspection

NOTICE: Cold and Hot in the following sentences express the temperature of the coils themselves.
Cold is from -10°C (14°F) to 50°C (104°F) and
Hot is from 50°C (104°F) to 100°C (212°F).

1. RH Ignition Coil:
REMOVE IGNITION COIL.
- Refer to Service and Repair.
2. LH Ignition Coil:
DISCONNECT IGNITION COIL CONNECTOR AND HIGH-TENSION CORD FROM IGNITION COIL.





3. INSPECT PRIMARY COIL RESISTANCE.
- Using an ohmmeter, measure the resistance between the positive (+) and negative (-) terminals.

Primary coil resistance (Cold): 0.36 - 0.55 Ohms
Primary coil resistance (Hot): 0.45 - 0.65 Ohms

- If the resistance is not as specified, replace the ignition coil.





4. INSPECT SECONDARY COIL RESISTANCE.
- Using an ohmmeter, measure the resistance between the positive (+) and high-tension terminals.

Secondary coil resistance (Cold): 9.0 - 15.4k Ohms
Secondary coil resistance (Hot): 11.4 - 18.1 k Ohms

- If the resistance is not as specified, replace the ignition coil.
5. RH Ignition Coil:
REINSTALL IGNITION COIL.
6. LH Ignition Coil:
RECONNECT IGNITION COIL CONNECTOR AND HIGH-TENSION CORD TO IGNITION COIL.
