The engine control module (ECM) checks the signal from the internal atmospheric pressure sensor.

The diagnostic trouble code (DTC) is stored if the signal from the internal atmospheric pressure sensor is lower than a certain value for a certain amount of time. The diagnostic trouble code (DTC) can be diagnosed when the engine is running.

Substitute Value 

• 1013 hPa (atmospheric pressure corresponding to sea level).

Possible Source 

• Damaged engine control module (ECM).

Fault symptom[s]
