DTC P0069

DTC P0069

Manifold absolute pressure/atmospheric pressure correlation

DETECTION CONDITION

The PCM monitors differences between intake manifold vacuum and atmospheric pressure. If the difference is below -12 kPa {-90 mmHg, -3.5 inHg} or above 12 kPa {90 mmHg, 3.5 inHg} 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 switch is turned off.

Diagnostic support note

This is a continuous monitor (CCM).
The MIL 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 the first drive cycle.
FREEZE FRAME DATA (Mode 2/Mode 12) is available.
The DTC is stored in the PCM memory.

POSSIBLE CAUSE

MAP sensor malfunction or substandard performance
BARO sensor malfunction or substandard performance
PCM malfunction

DIAGNOSTIC PROCEDURE

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA (MODE 12) HAS BEEN RECORDED Has the FREEZE FRAME DATA (Mode 12) been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA (Mode 12) on the repair order, then go to the next step.
2	VERIFY RELATED SERVICE BULLETINS AVAILABILITY Verify related Service Bulletins availability. Is any related Service Bulletins available?	Yes	Perform the repair or diagnosis according to the available Service Bulletins. If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	VERIFY RELATED PENDING CODE AND STORED DTC Turn the ignition switch to off, then to start the engine. Verify related PENDING CODE and stored DTC. Is the DTC P0107, P0108, P2228 or P2229 also present?	Yes	Go to the applicable DTC inspection. (See DTC P0107 ). (See DTC P0108 ). (See DTC P2228 ). (See DTC P2229 ).
3		No	Go to the next step.
4	IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA (MODE 2) Is the DTC P0069 on the FREEZE FRAME DATA (Mode 2)?	Yes	Go to the next step.
4		No	Go to the troubleshooting procedures for DTC on FREEZE FRAME DATA (Mode 2). (See DTC TABLE ).
5	INSPECT MAP SENSOR Inspect the MAP sensor. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR INSPECTION ). Is there any malfunction?	Yes	Replace the MAP sensor, then go to Step 7. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR REMOVAL/INSTALLATION ).
5		No	Go to the next step.
6	INSPECT BARO SENSOR Inspect the BARO sensor. (See BAROMETRIC PRESSURE (BARO) SENSOR INSPECTION ). Is there any malfunction?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION ).
6		No	Go to the next step.
7	VERIFY TROUBLESHOOTING OF DTC P0069 COMPLETED Make sure to reconnect all disconnected connectors. Turn the ignition switch to the ON position (Engine off). Clear the DTC from the PCM memory using the M-MDS. Start the engine. Stop the engine then turn the ignition switch to ON position (Engine off) Wait 15 sec. or more with the ignition switch to ON position (Engine off) Is the PENDING CODE for this DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION ).
7		No	Go to the next step.
8	VERIFY AFTER REPAIR PROCEDURE Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE ). Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE ).
8		No	DTC troubleshooting completed.
