Engine Sensor Electrical Connectors

 

1.

Unplug harness connector from crank position sensor lead (gray connector on bracket near ignition coil).

 

2.

Check resistance between terminals #1 and #2 of male connector.

-

Resistance should be approx. 1K ohms. If not, replace sensor.

 

3.

Check resistance between terminals #1 and #3, and between terminals #2 and #3 of male connector.

-

Resistance should be infinite (no continuity). If there is any continuity (even if resistance is very high) replace sensor.

 

4.

Check for open or grounded circuit between ECU terminals #29, #11, and #28, and sensor female harness connector terminals #1, #2, and #3
respectively, with ECU harness connector disconnected.
