DTC P2227 [MZ-CD 1.6 (Y6) (EURO4 emission level)]

id0102g6840700

DTC P2227

BARO sensor range/performance problem
DETECTION CONDITION
•  The PCM monitors atmospheric pressure using the BARO sensor built into the PCM. If the atmospheric pressure detected by the BARO sensor and the difference between the intake manifold pressure and the exhaust pressure on the upstream side of the DPF meet both of the following conditions, the PCM determines that the BARO sensor has a range/performance malfunction.
―  Difference with intake manifold pressure exceeds 15 kPa {0.15 kgf/cm2, 2.2 psi}
―  Difference with exhaust pressure on upstream side of diesel particulate filter exceeds 40 kPa {0.41 kgf/cm2, 5.8 psi}
POSSIBLE CAUSE
•  BARO sensor (integrated in PCM) malfunction
•  PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
•  Has the FREEZE FRAME DATA been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2
VERIFY RELATED REPAIR INFORMATION AVAILABILITY
•  Verify related service repair information availability.
•  Is any related repair information available?
Yes
Perform repair or diagnosis according to the available repair information.

Go to the next step.
3
VERIFY RELATED PENDING CODE AND/OR DTC
•  Switch the ignition to off, then to ON (engine off).
•  Perform the Pending Trouble Code Access Procedure and DTC Reading Procedure.
•  Is the following PENDING CODE/DTC also present?
―  P0069, P2454, P2455
Yes
Go to the applicable DTC inspection.
(See DTC P0069 [MZ-CD 1.6 (Y6) (EURO4 emission level)].)
(See DTC P2454 [MZ-CD 1.6 (Y6) (EURO4 emission level)].)
(See DTC P2455 [MZ-CD 1.6 (Y6) (EURO4 emission level)].)
No
Go to the next step.
4
VERIFY THAT DTC P2227 TROUBLESHOOTING IS COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Run the vehicle under the FREEZE FRAME DATA stored condition.
•  Is the same DTC present?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the PCM.
Go to the next step.
No
Go to the next step.
5
VERIFY AFTER REPAIR PROCEDURE
•  Perform the after repair procedure.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [MZ-CD 1.6 (Y6) (EURO4 emission level)].)
No
DTC troubleshooting completed.
