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 fuel gauge sender unit input voltage difference before and after PCM-calculated fuel consumption has reached 25.9 US qt. (24.5 liters). If fuel gauge sender unit operation reflects 5 percent less than PCM-calculated fuel consumption, PCM determines fuel gauge sender unit range/performance is in error. 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.
