DTC P2227:00 [PCM (SKYACTIV-D 2.2)]

id0102j5153100

DTC P2227:00

BARO sensor circuit range/performance problem
DETECTION CONDITION
•  With the following conditions met, a condition has continued for 1.8 s within 4 to 6 s after the ignition was switched OFF in which difference between the barometric pressure and intake air pressure is 50 kPa {0.51 kgf/cm2, 7.3 psi} or more and difference between the barometric pressure and exhaust gas pressure is 50 kPa {0.51 kgf/cm2, 7.3 psi} or more.
MONITORING CONDITIONS
―  Battery voltage: 10 V or more
―  The following DTCs are not detected:
•  MAP sensor No.2: P0106:00
•  Intake shutter valve: P1589:00
•  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 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 first drive cycle.
•  FREEZE FRAME DATA/Snapshot data is available.
•  DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION
•  Limits the engine torque or the upper limit of the engine speed.
•  Inhibits the auto DPF regeneration control.
•  Inhibits the compulsory DPF regeneration control.
•  Inhibits the EGR control.
•  PCM restricts engine-transaxle integration control. (ATX)
•  Inhibits engine-stop by operating the i-stop function.
POSSIBLE CAUSE
•  BARO sensor (built-into PCM) malfunction
•  Malfunction in the following sensors
―  MAP sensor No.2
―  Exhaust gas pressure sensor No.1
•  PCM malfunction

Diagnostic Procedure

STEP

INSPECTION

ACTION
1
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.
(See DTC TABLE [PCM (SKYACTIV-D 2.2)].)
2
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.
3
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.
4
VERIFY OTHER RELATED DTCs
•  Display the DTCs using the M-MDS.
•  Has any DTC related to the following sensors been stored?
―  MAP sensor No.2
―  Exhaust gas pressure sensor No.1
Yes
Repair the malfunctioning location according to the applicable DTC troubleshooting.
(See DTC TABLE [PCM (SKYACTIV-D 2.2)].)
No
Go to the next step.
5
INSPECT BARO SENSOR
•  Inspect the BARO sensor.
•  Is there any malfunction?
Yes
Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
No
Go to the next step.
6
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Clear the DTC from the PCM memory using the M-MDS.
•  Start the engine and idle it.
•  Switch the ignition to off and wait for 10 s or more.
•  Perform the Pending Trouble Code Access Procedure.
•  Is the PENDING CODE for this DTC present?
Yes
•  Inspect the following sensors and perform Step 6 again.
―  MAP sensor No.2
―  Exhaust gas pressure sensor No.1
•  If the malfunction recurs, replace the PCM, then go to the next step.
No
Go to the next step.
7
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [PCM (SKYACTIV-D 2.2)].)
No
DTC troubleshooting completed.
