Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-P052B00

Condition
The Engine control module (ECM) regulates the camshaft position (angle). The difference between requested angle and actual angle is stored in the Engine control module (ECM) during warm-up of the catalytic converter.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The camshaft angle is less than the requested during warm-up of the catalytic converter.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Cold engine.
- Warming-up of catalytic converter.

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
- None.

Possible source
- Poor engine oil quality.
- Low oil pressure.
- Damaged camshaft reset valve.
- Damaged VVT-unit.
