DTC P0069:00

Manifold absolute pressure/atmospheric pressure correlation problem

DETECTION CONDITION

• The PCM monitors the difference between the intake manifold vacuum and the atmospheric pressure. If the difference is below −12 kPa {−0.12 kgf/cm², −1.7 psi} or above 12 kPa {0.12 kgf/cm², 1.7 psi} when the following conditions are met, the PCM determines that there is a MAP sensor performance problem.

MONITORING CONDITIONS

• 12—15 s from when ignition is switched off.

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 (Mode 2)/Snapshot data is available.

• DTC is stored in the PCM memory.

STEP

INSPECTION

ACTION

1

• Perform the Freeze Frame PID Data Access Procedure.

  (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-G 2.5].)

• Is the DTC P0069:00 on FREEZE FRAME DATA (Mode 2)?

Yes

Go to the next step.

No

Go to the troubleshooting procedure for DTC on FREEZE FRAME DATA (Mode 2).

(See DTC TABLE [SKYACTIV-G 2.5].)

2

• Has the FREEZE FRAME DATA (Mode 2)/snapshot data been recorded?

Yes

Go to the next step.

No

Record the FREEZE FRAME DATA (Mode 2)/snapshot data on the repair order, then go to the next step.

3

• Verify related Service Bulletins and/or on-line repair information availability.

• Is any related repair information available?

Yes

Perform repair or diagnosis according to the available repair information.

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

No

Go to the next step.

4

• Switch the ignition off, then ON (engine off).

• Perform the Pending Trouble Code Access Procedure and DTC Reading Procedure.

  (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-G 2.5].)

• Is the PENDING CODE/DTC P0107:00, P0108:00, P2228:00 or P2229:00 also present?

Yes

Go to the applicable PENDING CODE or DTC inspection.

(See DTC P0107:00 [SKYACTIV-G 2.5].)

(See DTC P0108:00 [SKYACTIV-G 2.5].)

(See DTC P2228:00 [SKYACTIV-G 2.5].)

(See DTC P2229:00 [SKYACTIV-G 2.5].)

No

Go to the next step.

5

• Inspect the MAP sensor.

  (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR INSPECTION [SKYACTIV-G 2.5].)

• Is there any malfunction?

Yes

Replace the MAP sensor/IAT sensor No.2, then go to Step 7.

(See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO.2 REMOVAL/INSTALLATION [SKYACTIV-G 2.5].)

No

Go to the next step.

6

• Inspect the BARO sensor.

  (See BAROMETRIC PRESSURE (BARO) SENSOR INSPECTION [SKYACTIV-G 2.5].)

• Is there any malfunction?

Yes

Replace the PCM, then go to the next step.

(See PCM REMOVAL/INSTALLATION [SKYACTIV-G 2.5].)

No

Go to the next step.

7

• Always reconnect all disconnected connectors.

• Clear the DTC from the PCM memory using the M-MDS.

  (See AFTER REPAIR PROCEDURE [SKYACTIV-G 2.5].)

• Start the engine and warm it up completely.

• Perform the Pending Trouble Code Access Procedure.

  (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-G 2.5].)

• Is the PENDING CODE for this DTC present?

Yes

Repeat the inspection from Step 1.

• If the malfunction recurs, replace the PCM.

  (See PCM REMOVAL/INSTALLATION [SKYACTIV-G 2.5].)

Go to the next step.

No

Go to the next step.

8

• Perform the “AFTER REPAIR PROCEDURE”.

  (See AFTER REPAIR PROCEDURE [SKYACTIV-G 2.5].)

• Are any DTCs present?

Yes

Go to the applicable DTC inspection.

(See DTC TABLE [SKYACTIV-G 2.5].)

No

DTC troubleshooting completed.
