Diagnostic Trouble Code (DTC) Information
Diagnostic trouble code (DTC) information ECM-P053300
Condition
Engine control module (ECM) checks if the signal from the A/C pressure sensor is reasonable. If the signal from the A/C pressure sensor corresponds to a pressure that is higher than the A/C pressure sensor's normal working range, the control module interprets this as a malfunction and generates the diagnostic trouble code.
The diagnostic trouble code can be diagnosed when the ignition is on.
Substitute value
- Nothing.
Possible source
- The signal cable is short-circuited to voltage.
- Open circuit on the voltage feed.
- Open circuit on signal cable.
- Open circuit in ground cable.
- Damaged A/C pressure sensor.
Fault symptom[s]
