Detection Condition
WARNING: This page is about a different variant/trim than selected.
PCM monitors difference in intake manifold pressures when EGR is operated and when it is stopped. If difference is too large, PCM determines that EGR flow excessive. This is an intermittent monitor (EGR). 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.
