Throttle Actuator Control Motor Circuit Low

Throttle actuator a control motor circuit low.

Throttle actuator control motor circuit low.

Power supply for the throttle control. The throttle control motor relay is on off controlled by the ecm. How to repair p2102 code throttle actuator a control motor circuit low the throttle actuator is operated by the engine control module ecm and it opens and closes the throttle valve. The signal from the actuator is shown and can be downloaded.

P2102 description the throttle actuator is operated by the engine control module ecm and it opens and closes the throttle valve. Power supply for the throttle control motor is provided to the ecm via the throttle control motor relay. P2118 toyota description the electronic throttle control system etcs has a dedicated power supply circuit. This code means the pcm has determined that the tac throttle actuator control went out of range of their circuit causing an open circuit condition detected in the tac motor.

It s a long story but i will try to make it short and simple. The voltage bm is monitored and when the voltage is low less than 4 v the engine control module concludes that the etcs has a fault and current to the throttle actuator is cut when the voltage becomes unstable the etcs itself becomes unstable. The throttle actuator is operated by the engine control module ecm and it opens and closes the throttle valve. This generic powertrain engine diagnostic trouble code typically applies to all obdii equipped engines with electric throttle actuators but shows up more often in certain ford and nissan vehicles.

P2100 is an obd ii generic code which indicates that the throttle actuator control motor tacm circuit is open as detected by the engine control module ecm. New here recently became a proud subaru owner 2009 impreza outback sport. What does that mean. Power supply for the throttle control motor is provided to the ecm via throttle control motor relay.

When the pcm receives the input it will change the signals to the throttle actuator. With a lab scope a throttle valve control motor signal voltage is measured with the key on and engine off.
