If PCM detects actual throttle angle signal voltage is more than default throttle angle voltage after turning ignition off, PCM determines throttle actuator control on throttle body has malfunction. This is a Continuous Monitor (CM). MIL illuminates if PCM detects malfunction conditions 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.
