Diagnostic Trouble Code (DTC) Information

ECM-P222800 Atmospheric Pressure Circuit Low Input Signal

Condition







The diagnostic trouble code is generated if the engine control module (ECM) registers an internal fault that indicates that the signal from the internal atmospheric pressure sensor is faulty.

The diagnostic trouble code can be diagnosed when the ignition has been switched on for at least 15 seconds.

Substitute Value
- If the pressure sensor in the intake manifold is OK, a filtered value from such is used. Otherwise, the value 1000 hPa is set (corresponds to sea level).

Possible Source
- Damaged engine control module (ECM).

Fault Symptom[s]
- Malfunction indicator lamp (MIL) lit.
