Diagnostic Trouble Code (DTC) Charts and Descriptions
P2227 - Barometric Pressure Sensor A Circuit Range/Performance (Continued)
KA Refer to the Description, Possible Causes and Diagnostic Aids for the DTC.
All others GO to Pinpoint Test DO.
P2228 - Barometric Pressure Sensor A Circuit Low
For Fiesta
Description: This DTC sets when the signal from the barometric pressure (BARO) sensor is below the minimum threshold.
Possible Causes: • Damaged BARO sensor
• Damaged PCM
Diagnostic Aids: The BARO sensor is integral to the PCM.
When the BARO signal is less than the 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 Section 2, Flash Electrically Erasable Programmable Read Only Memory (EEPROM).
For KA
Description: This DTC sets when the signal from the barometric pressure (BARO) sensor is below the minimum threshold.
Possible Causes: • Damaged BARO sensor
• Damaged PCM
Diagnostic Aids: The BARO sensor is integral to the PCM.
When the BARO signal is less than the 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 Section 2, Flash Electrically Erasable Programmable Read Only Memory (EEPROM).
For All Others
Description: This DTC sets when the barometric pressure (BARO) reading is abnormally low indicating an extreme high
altitude.
Possible Causes: • Damaged BARO sensor
Diagnostic Aids: When the BARO signal is less than the 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 outside the operational range.
