id0102f3153100

DTC P2227:00

BARO sensor range/performance malfunction
DETECTION CONDITION
•  The PCM monitors the input signal from the barometric pressure sensor. If the difference between the barometric pressure input from the barometric pressure sensor and the manifold absolute pressure is more than 10 kPa {75 mmHg, 3.0 inHg}, the PCM determines that there is a malfunction in the barometric pressure sensor.
Monitoring conditions
―  Following conditions are met:
•  Battery voltage: 8—20 V
•  Engine coolant temperature: more than 60 °C {140 °F}
•  Intake air temperature: more than -7 °C {19 °F}
Diagnostic support note
•  The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
•  PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
•  FREEZE FRAME DATA (mode2) and snapshot data are available.
•  DTCs are stored in the PCM memory.
POSSIBLE CAUSE
•  BARO sensor (integrated in PCM) malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA (MODE2) OR SNAPSHOT DATA HAVE BEEN RECORDED
•  Have FREEZE FRAME DATA (mode2) or snapshot data been recorded?
Yes
