DTC P0069 | Manifold absolute pressure/atmospheric pressure correlation
--- | ---
DETECTION CONDITION | • 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 CONDITION - 12-15 s from when ignition switch is turned off. - Intake air temperature is above -10°C {14°F}. - Engine coolant temperature is 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 PCM. • PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle. • FREEZE FRAME DATA is available. • DTCs are stored in the PCM memory.
POSSIBLE CAUSE | • MAP sensor malfunction or substandard performance • BARO sensor malfunction or substandard performance

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY FREEZE FRAME DATA AND DIAGNOSTIC MONITORING TEST RESULTS HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded? | Yes | Go to the next step.
No | Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2 | VERIFY RELATED REPAIR 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 STORED DTC • Turn the ignition switch to off then start the engine. • Have DTC P0107, P0108, P2228 or P2229 been stored? | Yes | Inspect and repair DTC P0107, P0108, P2228 or P2229.
No | Go to the next step.
4 | IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA • Is DTC P0069 on the FREEZE FRAME DATA? | Yes | Go to the next step.
No | Go to troubleshooting procedures for the DTC on the FREEZE FRAME DATA.
5 | INSPECT MAP SENSOR STUCK OPEN OR CLOSED • Inspect MAP sensor. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR INSPECTION [L3 Turbo].) • Is the MAP sensor normal? | Yes | Go to the next step.
No | Replace the MAP sensor, then go to step 7. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR/BOOST AIR TEMPERATURE SENSOR REMOVAL/INSTALLATION [L3 Turbo].)
6 | INSPECT BARO SENSOR • Inspect the BARO sensor. (See BAROMETRIC PRESSURE (BARO) SENSOR INSPECTION [L3 Turbo].) • Is the BARO sensor normal? | Yes | Go to the next step.
No | Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [L3 Turbo].)
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 memory using the WDS or equivalent. • Start the engine. • Is the same 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.
