Detection Condition
PCM monitors fuel gauge sending unit input voltage difference before and after PCM-calculated fuel consumption has reached 5.1 gallons. If fuel gauge sending unit operation reflects 5 percent less than PCM-calculated fuel consumption, PCM determines that fuel gauge sending unit range/performance is in error. This is a Continuous Monitor (CM). MIL illuminates if PCM detects malfunction condition in 2 consecutive drive cycles. Pending code is available if PCM detects malfunction condition during first drive cycle. Freeze Frame Data is available and DTC is stored in PCM memory.
