Signal missing. Permanent fault

Checking the terminal








- Ignition off
- Disconnect the connector for the camshaft position (CMP) sensor.
Check the connector for the camshaft position (CMP) sensor. Check 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 off.
Check the cable between camshaft position (CMP) sensor connector terminal #2 and engine control module connector terminal #58. Check the cable between camshaft position (CMP) sensor connector #3 (control module side) and engine control module terminal #83. Check for an open-circuit according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault. Check for a short-circuit to ground according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault. Check for a short-circuit to supply voltage 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 ground lead

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

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 0 ohms.

OK - Defective camshaft position (CMP) sensor

Not OK - Checking the ground lead

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

Defective camshaft position (CMP) sensor
Try a new camshaft position (CMP) sensor according to Replacing camshaft position (CMP) sensor Removal and Replacement.

Continue - Verification

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

Checking the ground lead
Check the cable between camshaft position (CMP) sensor connector terminal #1 and engine control module (ECM) connector terminal #79. Check for an open-circuit according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
Remedy as necessary.













Continue - Verification

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

Verification








- Reconnect the connectors, reinstall components etc.
- Start the engine
- Rev the engine a couple of times.
Read off diagnostic trouble codes (DTCs).





Has the diagnostic trouble code (DTC) ECM-32 changed status to intermittent?

Yes - FAULT FOUND

No - No Fault Found Fault-tracing information

Information

Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.

Do you want to exit fault-tracing?

Yes - Exit fault-tracing

No - Attempt New Test
