Celica GT Convertible L4-2164cc 2.2L DOHC MFI (1997)
Ignition Coil: Testing and Inspection
IGNITION COIL 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 (122°F) and Hot
is from 50°C (122°F) to 100°C (212°F).
1. DISCONNECT IGNITION COIL CONNECTOR AND HIGH-TENSION CORD FROM IGNITION COIL
2. INSPECT PRIMARY COIL RESISTANCE
Using an ohmmeter. measure the resistance between the positive (+) and negative (-) terminals.
Primary coil resistance:
Cold 0.38 - 0.55 Ohms
Hot 0.45 - 0.65 Ohms
If the resistance is not as specified. replace the ignition coil.
3. INSPECT SECONDARY COIL RESISTANCE
Using an ohmmeter, measure the resistance between the positive (+) and high-tension terminals.
Secondary coil resistance:
Cold 9.0 - 15.4 K ohms
Hot 11.4 - 18.1 K ohms
If the resistance is not as specified, replace the ignition coil.
4. RECONNECT HIGH-TENSION CORD AND IGNITION COIL CONNECTOR TO IGNITION COIL
