Camshaft Position Sensor: Testing and Inspection




CAMSHAFT POSITION SENSOR
1. Remove distributor from engine. (Camshaft position sensor harness connector should remain connected.)
2. Disconnect ignition wires and center cable from distributor.
3. Turn ignition switch "ON".




4. Rotate distributor shaft slowly by hand and check voltage between terminals 1, 2 and ground.
Measure with circuit tester in 100 mV range, AC.

Tester pointer fluctuates: OK
Tester pointer does not fluctuate: NG

If NG, replace distributor assembly with camshaft position sensor.




5. Visually check signal plate for damage or dust.
After this inspection, diagnostic trouble code No. 11 might be displayed with camshaft position sensor functioning properly. Erase the stored memory.
