P2227 - Barometric Pressure Sensor 'A' Circuit Range/Performance

Possible causes
- Faulty Barometric Pressure (BARO) sensor
- Barometric Pressure (BARO) sensor harness is open or shorted
- Barometric Pressure (BARO) sensor circuit poor electrical connection
- Faulty Powertrain Control Module (PCM)
Possible symptoms

P2227 Description

The Powertrain Control Module (PCM) continuously monitors this sensor for concerns. The test fails when the Barometric Pressure (BARO) Parameter Identification (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.
