Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-P242200

Condition




The engine control module (ECM) checks the function of the valve in the leakage diagnosis unit pump by measuring the current through the leakage diagnosis pump.
After the initial reference phase in the leakage diagnosis, the air flow is directed over from the reference leak to the tank system and starts to pressurize it. If the control module registers that power consumption during the reference phase is unreasonable, it interprets this as the valve in the pump being damaged and the diagnostic trouble code is generated.
The diagnostic trouble code can be diagnosed when leakage diagnosis is running.

Substitute value
- Leakage diagnosis interrupted.

Possible source
- Dirt or moisture in the pump.
- The pump valve has seized.
- Damage leakage diagnosis pump.

Fault symptom[s]
