Component Inspection




IGNITION COIL

If NG, replace distributor assembly as a unit.




POWER TRANSISTOR
1. Disconnect camshaft position sensor & power transistor harness connector and ignition coil harness connector.
2. Check power transistor resistance between terminals (2) and (8).




If NG, replace distributor assembly.
