Crankshaft Position Sensor: Testing and Inspection
If either the CYL or TDC sensor are not satisfactory, they should be replaced together.
CYL Sensor
1.
Disconnect sensor electrical connector, then measure resistance between white and orange wire terminals. Resistance should be 650-850 ohms.
2.
Check for continuity between between white terminal and body ground and orange terminal and body ground. There should be no continuity.
TDC Sensor
1.
Disconnect connector of distributor.
2.
Measure resistance between orange/blue and white/blue terminals of sensor. Resistance should be 650-850 ohms.
3.
Check for continuity between white/blue terminal and body ground and orange/blue terminal and body ground. There should be no continuity.
