DTC P2227: Barometric Pressure Sensor A Circuit Range/Performance

WARNING: This page is about a different variant/trim than selected.

P2227 - BAROMETRIC PRESSURE SENSOR A CIRCUIT RANGE/PERFORMANCE

For Fiesta
Description: This DTC sets when there is an out of range condition in the control circuit.
Possible Causes: Damaged barometric pressure (BARO) sensor Damaged PCM
Diagnostic Aids: The BARO sensor is integral to the PCM. A BARO reading less than 50 kPa (7.25 psi) indicates a concern. Clear the PCM DTCs. Repeat the self-test. If the DTC is retrieved again, install a new PCM. Refer to FLASH ELECTRICALLY ERASABLE PROGRAMMABLE READ ONLY MEMORY (EEPROM) .
For Vehicles With 3.5L GTDI Engine
Description: This DTC sets when either of the following conditions are present. When the BARO PID does not correlate with the TIP and the MAP PIDs at ignition ON. When the MAP and TIP_PRS_BOOST PIDs correlate with the engine running, but the TIP_PRS_BOOST PID does not correlate with the BARO PID at idle.
Possible Causes: Damaged BARO sensor Damaged PCM
Diagnostic Aids: This DTC is only operational between 1, 000 feet below sea level to 15, 000 feet above sea level, it should be disregarded if set outside the operational range.
For All Others
Description: This DTC sets when the (BARO) does not correlate with an inferred barometric pressure calculation based on the manifold absolute pressure (MAP), supercharger inlet pressure (SIP), or mass airflow (MAF) value.
Possible Causes: Damaged BARO sensor Damaged PCM
Diagnostic Aids: This DTC is only operational between 1, 000 feet below sea level to 15, 000 feet above sea level, it should be disregarded if set outside the operational range.
