id0102s8153100

DTC P2227:00

BARO sensor circuit range/performance problem

DETECTION CONDITION
•  Any one 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. (The check engine light may be illuminated depending on the malfunction conditions.)
•  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

Diagnostic Procedure

STEP

INSPECTION

ACTION

1
RECORD VEHICLE STATUS AT TIME OF DTC DETECTION TO UTILIZE WITH REPEATABILITY VERIFICATION
Note
•  Recording can be facilitated using the screen capture function of the PC.
•  Record the FREEZE FRAME DATA/snapshot data on the repair order.
Go to the next step.
2
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related Service Information available?
Yes
Perform repair or diagnosis according to the available Service Information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA
•  Perform the Freeze Frame PID Data Access Procedure.
•  Is the DTC P2227:00 on FREEZE FRAME DATA?
Yes
Go to the next step.
No
Go to the troubleshooting procedure for DTC on FREEZE FRAME DATA.
4
INSPECT BARO SENSOR
•  Is there any malfunction?
Yes
Replace the PCM, then go to the next step.
No
Go to the next step.
5
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Clear the DTC from the PCM memory using the M-MDS.
•  Start the engine and idle it.
•  Switch the ignition off and wait for 10 s or more.
•  Perform the DTC Reading Procedure.
•  Is the same DTC present?
Yes
Replace the PCM, then go to the next step.
No
Go to the next step.
6
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
No
DTC troubleshooting completed.
