Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-P053200

Condition
The engine control module (ECM) checks if the signal from the air conditioning (A/C) pressure sensor is within its permitted range.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The signal from the pressure sensor corresponds to a lower pressure than the normal operating value.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition on.

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
No substitute value.

Possible source
- Open-circuit in the power supply.
- Open-circuit in the signal cable.
- Open-circuit in the ground lead.
- Damaged A/C pressure sensor.

Fault symptom[s]
- A/C system does not operate
