DTC P0069:00 [L5]: Notes

WARNING: This page is about a different car, the 2009 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

DETECTION CONDITIONS & POSSIBLE CAUSES

DTC P0069:00	Manifold absolute pressure/atmospheric pressure correlation
DETECTION CONDITION	The PCM monitors difference 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 is switched off 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 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
