DTC P0069:00 [L3 Turbo]

id0102b7300000

DTC P0069:00

Manifold absolute pressure/atmospheric pressure correlation problem
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
― Intake air temperature: above −10 °C {14 °F}
― Engine coolant temperature: above 70 °C {158 °F}
Diagnostic support note
• This is a continuous monitor (CCM).
• 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)/Snapshot data is available.
• DTCs are stored in the PCM memory.
POSSIBLE CAUSE
• MAP sensor malfunction
• BARO sensor (built-in PCM) malfunction
• PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA (MODE 2)
• Perform the Freeze Frame PID Data Access Procedure. (See ON-BOARD DIAGNOSTIC TEST [L3 Turbo].)
• Is the DTC P0069:00 on FREEZE FRAME DATA (Mode 2)?
Yes
Go to the next step.
No
Go to the troubleshooting procedures for DTC on FREEZE FRAME DATA (Mode 2).
(See DTC TABLE [L3 Turbo].)
2
VERIFY FREEZE FRAME DATA (MODE 2)/SNAPSHOT DATA HAS BEEN RECORDED
• 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 repair order, then 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 RELATED PENDING CODE AND STORED DTC
• Turn the ignition switch off, then to the ON position (engine off).
• Perform the DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [L3 Turbo].)
• Is the DTC P0107:00, P0108:00, P2228:00 or P2229:00 present?
Yes
Go to the applicable DTC inspection.
(See DTC P0107:00 [L3 Turbo].)
(See DTC P0108:00 [L3 Turbo].)
(See DTC P2228:00 [L3 Turbo].)
(See DTC P2229:00 [L3 Turbo].)
No
Go to the next step.
5
INSPECT MAP SENSOR STUCK OPEN OR CLOSED
• Inspect MAP sensor. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR INSPECTION [L3 Turbo].)
• Is there any malfunction?
Yes
Replace the MAP sensor/boost air temperature sensor, then go to Step 7.
(See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR/BOOST AIR TEMPERATURE SENSOR REMOVAL/INSTALLATION [L3 Turbo].)
No
Go to the next step.
6
INSPECT BARO SENSOR
• Inspect the BARO sensor. (See BAROMETRIC PRESSURE (BARO) SENSOR INSPECTION [L3 Turbo].)
• Is there any malfunction?
Yes
Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [L3 Turbo].)
No
Go to the next step.
7
VERIFY DTC TROUBLESHOOTING COMPLETED
• Make sure to reconnect all disconnected connectors.
• Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [L3 Turbo].)
• Start the engine.
• Perform the Pending Trouble Code Access Procedure. (See ON-BOARD DIAGNOSTIC TEST [L3 Turbo].)
• Is the PENDING CODE for this DTC present?
Yes
Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [L3 Turbo].)
No
Go to the next step.
8
VERIFY AFTER REPAIR PROCEDURE
• Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [L3 Turbo].)
• Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [L3 Turbo].)
No
DTC troubleshooting completed.
