Component Inspection

IGNITION COIL
1. Disconnect ignition coil harness connector.
2. Check resistance as shown in the figure.




For checking secondary coil, remove distributor cap and measure resistance between coil tower metal tip (9) and terminal (7).




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.




RESISTOR
1. Disconnect resistor harness connector.
2. Check resistance between terminals (a) and (b).

Resistance: Approximately 2.2 kohms at 25°C (77°F)

If NG, replace resistor.
