P2227 - BAROMETRIC PRESSURE SENSOR A CIRCUIT RANGE/PERFORMANCE
| For Fiesta | |||
| Description: | The powertrain control module (PCM) continuously monitors this sensor for concerns. This DTC sets when the PCM detects an out of range condition in the control circuit. | ||
| Possible Causes: |
|
||
| 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 All Others | |||
| Description: | The powertrain control module (PCM) continuously monitors this sensor for concerns. The test fails when the barometric pressure (BARO) PID does not correlate with the throttle intake pressure (TIP) or the manifold absolute pressure (MAP) PIDs at ignition ON. This DTC sets when the PCM detects an out of range condition in the control circuit. | ||
| Possible Causes: |
|
||
| 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 out side the operational range. | ||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory |
| Fiesta | Refer to the Description, Possible Causes and Diagnostic Aids for the DTC in table. | ||
