Detection Condition

PCM monitors differences between intake manifold vacuum and atmospheric pressure at idle. If difference is less than 1.9 in. Hg (6.4 kPa), PCM determines that there is a Manifold Absolute Pressure (MAP) sensor performance problem. This is a Continuous Monitor (CM). MIL illuminates if PCM detects malfunction condition in two consecutive drive cycles or in one drive cycle while DTC for same malfunction has been stored in PCM. PENDING CODE is available if PCM detects malfunction condition during first drive cycle. FREEZE FRAME DATA is available. DTC is stored in PCM memory.
