Checking the terminal








- Ignition off
- Disconnect the connector for the camshaft position (CMP) sensor.
Check the connector for the camshaft position (CMP) sensor for contact resistance and oxidation according to Checking wiring and terminals. Permanent fault Checking Wiring And Terminals. Permanent Fault.
Remedy as necessary.





Was a fault detected?

Yes - Verification

No - Checking the signal cable

-------------------------------------------------

Checking the signal cable




- Ignition on.
Connect a voltmeter between connector terminal 2 for the camshaft position (CMP) sensor (control module side) and ground and between terminal 3 and ground.









In both cases the voltmeter should display approximately 5 V.

OK - Checking the ground lead

Not OK - Checking cables

-------------------------------------------------

Checking the ground lead




- Ignition off.
Connect an ohmmeter between connector terminal 1 on the camshaft position (CMP) sensor (control module side) and the ground terminal.









The ohmmeter should read approximately 0ohms.

OK - Defective camshaft position (CMP) sensor

Not OK - Checking the ground lead

-------------------------------------------------

Defective camshaft position (CMP) sensor
