The ECM monitors the battery supply voltage applied to the throttle actuator. When the power supply voltage (+BM) drops below 4 V for 0.8 seconds or more, the ECM interprets this as an open in the power supply circuit (+BM). The ECM illuminates the MIL and stores the DTC. If the malfunction is not repaired successfully, the DTC is stored 5 seconds after the engine is next started.
