Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition
A toothed wheel is installed on the camshaft, the toothed wheel consists of a number of teeth. Teeth position on the toothed wheel represents the segments into which the camshaft is divided. Engine control module (ECM) reads off the toothed wheel's teeth using the camshaft sensor.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The camshaft's segments are too few under a certain crankshaft rpm.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Engine running.
- The voltage to the control module is higher than 10,5 V.
- Engine speed (RPM) higher than 500 rpm.

Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.





Substitute value
- The control module uses the impulse sensor's signal.
- Variable valve timing control is blocked.

Possible source
- Contact resistance and oxidation in the terminals.
- Open-circuit in the signal cable.
- Short-circuit to supply voltage in the signal cable.
- Short-circuit to ground in the signal cable.
- Incorrectly installed camshaft position sensor.
- Damaged camshaft position (CMP) sensor.

Fault symptom[s]
- Malfunction indicator light (MIL), on
