DTC P2227-00: BARO Sensor Circuit Range/Performance Problem: Notes

DTC P2227:00 DETECTION CONDITION AND POSSIBLE CAUSE

DTC P2227:00	BARO sensor circuit range/performance problem
DETECTION CONDITION	Anyone of the following conditions is met: The condition has continued for 2 s in which difference in barometric pressure measured and manifold absolute pressure is more than 12.0 kPa {0.122 kgf/cm² , 1.74 psi}, difference in manifold absolute pressure and turbocharger/supercharger boost pressure is more than 12.0 kPa {0.122 kgf/cm² , 1.74 psi} and difference in manifold absolute pressure and exhaust pressure is more than 25.8 kPa {0.263 kgf/cm² , 3.74 psi}. The condition has continued for 2 s in which difference in barometric pressure measured and manifold absolute pressure is less than -12.0 kPa {-0.122 kgf/cm² , -1.74 psi}, difference in manifold absolute pressure and turbocharger/supercharger boost pressure is less than -12.0 kPa {-0.122 kgf/cm² , -1.74 psi} and difference in manifold absolute pressure and exhaust pressure is less than -25.8 kPa {-0.263 kgf/cm² , -3.74 psi}. MONITORING CONDITIONS Period vehicle being left: 6 h or more Battery voltage: 8 V or more Within 20 s after engine start The following DTCs are not detected: MAP sensor: P0107:00, P0108:00 Boost pressure sensor: P0237:00, P0238:00 Exhaust gas pressure sensor: P0472:00, P0473:00 BARO sensor: P2228:00, P2229:00 Diagnostic support note This is a continuous monitor (CCM). The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle. FREEZE FRAME DATA/Snapshot data is available. DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION	Fixes the barometric pressure for the engine control at 101.32 kPa {1.0332 kgf/cm² , 14.695 psi}.
POSSIBLE CAUSE	BARO sensor (built-into PCM) malfunction PCM malfunction
