DTC P0069: Notes
DTC P0069 DETECTION CONDITION AND POSSIBLE CAUSES
| 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.
