DTC P0069 [L8, LF]

id0102b1802400

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 ― 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). • 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.
No | Record the FREEZE FRAME DATA (Mode 12) on the repair order, then go to the next step.
2 | 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.
3 | VERIFY RELATED STORED DTCS • Turn the ignition switch to off then start the engine. • Perform the DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [L8, LF].) • Is the DTC P0107, P0108, P2228 or P2229 also present? | Yes | Go to the applicable DTC troubleshooting. (See DTC P0107 [L8, LF].) (See DTC P0108 [L8, LF].) (See DTC P2228 [L8, LF].) (See DTC P2229 [L8, LF].)
No | Go to the next step.
4 | IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA (MODE 2) • Perform the Freeze Frame PID Data Access Procedure. (See ON-BOARD DIAGNOSTIC TEST [L8, LF].) • Is the DTC P0069 on the FREEZE FRAME DATA (Mode 2)? | Yes | Go to the next step.
No | Go to the DTC troubleshooting on FREEZE FRAME DATA (Mode 2). (See DTC TABLE [L8, LF].)
5 | INSPECT MAP SENSOR • Inspect MAP sensor. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR INSPECTION [L8, LF].) • Is there any malfunction? | Yes | Replace the MAP sensor, then go to step 7. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR REMOVAL/INSTALLATION [L8, LF].)
No | Go to the next step.
6 | INSPECT BARO SENSOR • Inspect the BARO sensor. (See BAROMETRIC PRESSURE (BARO) SENSOR INSPECTION [L8, LF].) • Is there any malfunction? | Yes | Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [L8, LF].)
No | Go to the next step.
7 | VERIFY DTC TROUBLESHOOTING 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. (See AFTER REPAIR PROCEDURE [L8, LF].) • Start the engine and warm it up completely. • Perform the DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [L8, LF].) • Is the same DTC present? | Yes | Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [L8, LF].)
No | Go to the next step.
8 | VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [L8, LF].) • Are any DTCs present? | Yes | Go to the applicable DTC troubleshooting. (See DTC TABLE [L8, LF].)
No | DTC troubleshooting completed.
