Detection Condition

WARNING: This page is about a different car, the 2003 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

PCM monitors EGR boost sensor solenoid valve control signal. If PCM 104-pin harness terminal No. 47 voltage does not change when EGR boost sensor solenoid valve is switched to ON or OFF, PCM determines EGR boost sensor solenoid valve circuit has a malfunction. 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.
