Component Inspection
- Check Ignition Coil
- IG "OFF". Disconnect ignition coil connector.
- Measure resistance between power and signal terminals of ignition coil connector. (Measurement "A").
- Measure resistance between power terminal of ignition coil connector and output terminal of secondary ignition coil. (Measurement "B").IGNITION COIL SPECIFICATION
Resistance (Ω) "A" Primary Coil "B" Secondary Coil 0.62 ± 10% (20°C) (68°F) 7.0k ± 15% (20°C) (68°F) - Is the measured resistance within specification?
YES
- Substitute with a known - good PCM and check for proper operation. If the problem is corrected, replace PCM and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NO
- Substitute with a known - good ignition coil and check for proper operation. If the problem is corrected, replace ignition coil and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
