DTC P2228:00 [PCM (SKYACTIV-X)]

id0102u9153200

Outline

System malfunction location

BARO sensor circuit low input

Detection condition

•  The PCM monitors input voltage from the BARO sensor. If the input voltage is low for 5 s, the PCM determines that the BARO sensor circuit has a malfunction.

Fail-safe

•  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

Results

Action

1

IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA

•  Is the DTC P2228:00 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-X)].)

2

RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION

•  Record the freeze frame data/snapshot data.

Note

•  Recording can be facilitated using the screen capture function of the PC.

—

Go to the next step.

3

VERIFY RELATED REPAIR INFORMATION OR SERVICE INFORMATION AVAILABILITY

•  Verify related Service Bulletins, on-line repair information, or Service Information availability.

•  Is any related Information available?

Yes

Perform repair or diagnosis according to the available information.

•  If the vehicle is not repaired, go to the next step.

No

Go to the next step.

4

INSPECT BARO SENSOR FOR MALFUNCTION

•  Inspect the applicable part.
(See BAROMETRIC PRESSURE (BARO) SENSOR INSPECTION [SKYACTIV-X 2.0].)

•  Is the part normal?

Yes

Go to the next step.

No

Repair or replace the malfunctioning location and perform the repair completion verification.

(See PCM REMOVAL/INSTALLATION [SKYACTIV-X 2.0].)

Repair completion verification 1

VERIFY THAT VEHICLE IS REPAIRED

•  Install/connect the part removed/disconnected during the troubleshooting procedure.

•  Clear the DTC recorded in the memory.
(See CLEARING DTC.)

•  Replicate the vehicle conditions at the time the DTC was detected using the following procedure.

―  Perform the KOEO or KOER self test.
(See DTC INSPECTION.)

•  Perform the DTC inspection for the PCM.
(See DTC INSPECTION.)

•  Is the same Pending DTC present?

Yes

Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.

(See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [(E)].)

If the CAN communication is normal, perform the diagnosis from Step 1.

•  If the malfunction recurs, replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [SKYACTIV-X 2.0].)

No

Go to the next step.

Repair completion verification 2

VERIFY IF OTHER DTCs DISPLAYED

•  Perform the DTC inspection.
(See DTC INSPECTION.)

•  Are any other DTCs displayed?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

No

DTC troubleshooting completed.
