P2229 - BAROMETRIC PRESSURE SENSOR A CIRCUIT HIGH
| For Fiesta | |||
| Description: | The powertrain control module (PCM) continuously monitors this sensor for concerns. Checks whether the signal from the barometric pressure (BARO) sensor is above the maximum threshold. | ||
| Possible Causes: |
|
||
| Diagnostic Aids: | The BARO sensor is integral to the PCM. When the BARO signal is greater than a calibrated threshold, a concern is indicated. 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: | Checks whether the BARO reading is abnormally high indicating an extreme low altitude. | ||
| Possible Causes: |
|
||
| Diagnostic Aids: | When the BARO signal is greater than a calibrated threshold for greater than 100 ms, a concern is indicated. 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. |
