IG–7 IGNITION SYSTEM – (2JZ–GE) 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 2. DISCONNECT 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 Ω Hot: 0.45–0.65 Ω 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: 9.0–15.4 kΩ Hot: 11.4–18.1 kΩ If the resistance is not as specified, replace the ignition coil. 5. RECONNECT HIGH–TENSION CORD TO IGNITION COIL 6. RECONNECT IGNITION COIL CONNECTOR Ohmmeter Positive (+) Terminal DISTRIBUTOR 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. REMOVE DISTRIBUTOR CAP WITHOUT DISCONNECTING HIGH–TENSION CORDS 2. REMOVE ROTOR
