Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-P004800

Condition
The Engine control module (ECM) regulates the turbo pressure using a turbo control valve.
The control module has integrated functions to check the function of the turbo control valve.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Control signal is too high.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition switch position II.
- Battery voltage higher than 10.5 V.

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
- Initial boost pressure.

Possible source
- Short-circuit to supply voltage in the signal cable.
- Damaged turbocharger (TC) control valve.

Fault symptom[s]
- Poor performance
