Detection Condition

DTC is set when Powertrain Control Module (PCM) detects difference in intake manifold pressure between open EGR and closed EGR is too small. This is a continuous monitor (CCM). MIL illuminates if PCM detects malfunction condition in 2 consecutive drive cycles. Diagnostic Monitoring Test Results and Pending code are available if PCM detects malfunction conditions during first drive cycle. Freeze Frame Data is available and DTC is stored in the PCM memory.
