P2229 Barometric Pressure (BARO) Sensor Circuit High Voltage
Possible causes
– BARO sensor malfunction
– Connector or terminal malfunction
– Open circuit in wiring between BARO sensor and PCM
– Short to power circuit in wiring between BARO sensor and PCM
– Powertrain Control Module (PCM) malfunction
– Connector or terminal malfunction
– Open circuit in wiring between BARO sensor and PCM
– Short to power circuit in wiring between BARO sensor and PCM
– Powertrain Control Module (PCM) malfunction
P2229 Description
Powertrain Control Module (PCM) monitors input voltage from BARO sensor. If input voltage at PCM terminal 1AG is above 4.43 V, PCM determines that BARO sensor circuit has malfunction.
