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

DETECTION CONDITION AND POSSIBLE CAUSE

DTC P2227:00	BARO sensor circuit range/performance problem
DETECTION CONDITION	The condition has continued for 2 s in which difference in barometric pressure and manifold absolute pressure is 30 kPa {0.31 kgf/cm² , 4.4 psi} or more, difference in barometric pressure and turbocharger/supercharger boost pressure is 30 kPa {0.31 kgf/cm² , 4.4 psi} or more and difference in barometric pressure and exhaust pressure is 30 kPa {0.31 kgf/cm² , 4.4 psi} or more. 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
