DTC P0069:00 |
Manifold absolute pressure - barometric pressure correlation |
|---|---|
|
DETECTION CONDITION
|
• The PCM monitors the MAP sensor signal at PCM terminal 2AD and the barometric pressure at the BARO sensor in the PCM. If the difference in the values between the MAP sensor and BARO sensor exceed the threshold during idling, the PCM determines that there is a correlation error between the manifold absolute pressure and the barometric pressure.
|
|
POSSIBLE CAUSE
|
• Poor connection of connector or terminals
• MAP sensor malfunction
• Blockage at MAP sensor detection area, or foreign matter adhering
• BARO sensor (built-in PCM) malfunction
• PCM malfunction

• Is there any malfunction?
|
Yes
|
Go to the next step.
|
|
No
|
Intermittent concern exists.
Go to the Step 7.
|
||
|
6
|
VERIFY IF CAUSE IS FOREIGN MATTER ADHERING TO MAP SENSOR DETECTION AREA
• Verify that there is no foreign matter adhering to the MAP sensor detection area.
• Is foreign matter adhering?
|
Yes
|
Remove the foreign matter, then go to the next step.
|
|
No
|
