DTC P0069:00 [PCM (SKYACTIV-G)]
SM2334432
id0102t4300000
Outline
|
System malfunction location |
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.
Precondition
• 12—15 s from when ignition is switched off.
|
|
Fail-safe
|
• Not applicable
|
|
Possible cause
|
• MAP sensor malfunction
• BARO sensor (built-into PCM) malfunction
• PCM malfunction

|
5
|
INSPECT MAP SENSOR FOR MALFUNCTION
• Inspect the applicable part. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR INSPECTION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].) (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR INSPECTION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
• Is the part normal?
|
Yes
|
Go to the next step.
|
|
No
|
Repair or replace the malfunctioning location and perform the repair completion verification.
|
||
|
6
|
INSPECT BARO SENSOR FOR MALFUNCTION
• Inspect the applicable part. (See BAROMETRIC PRESSURE (BARO) SENSOR INSPECTION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].) (See BAROMETRIC PRESSURE (BARO) SENSOR INSPECTION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)

Repair completion verification 1
|
VERIFY THAT VEHICLE IS REPAIRED
• Install/connect the part removed/disconnected during the troubleshooting procedure.
• Clear the DTC recorded in the memory. (See CLEARING DTC.)
• Replicate the vehicle conditions at the time the DTC was detected using the following procedure.
• Perform the DTC inspection for the PCM. (See DTC INSPECTION.)
• Is the same Pending DTC present?
|
Yes
|
Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.
If the CAN communication is normal, perform the diagnosis from Step 1.
• If the malfunction recurs, replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].) (See PCM REMOVAL/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
