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 changes in input voltage from neutral switch. If PCM does not detect PCM 30-pin harness connector terminal "1W" voltage change from neutral switch when gears are shifted more than 14 times and vehicle speed is more than 18.6 MPH, PCM determines neutral switch circuit has 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.
