Throttle Actuator Control Motor Circuit Low

Throttle actuator control motor circuit open tacm what the p2100 code means.

Throttle actuator control motor circuit low.

P2118 toyota description the electronic throttle control system etcs has a dedicated power supply circuit. It s a long story but i will try to make it short and simple. P2102 throttle actuator control motor circuit low. Power supply for the throttle control motor is provided to the ecm via the throttle control motor relay.

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. The throttle control motor relay is on off controlled by the ecm. 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. 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.

With a lab scope a throttle valve control motor signal voltage is measured with the key on and engine off. When the pcm receives the input it will change the signals to the throttle actuator. 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. To help determining whether the throttle valve control motor is functioning correctly different deviations from the example signal are mentioned along with possible causes.

New here recently became a proud subaru owner 2009 impreza outback sport. Power supply for the throttle control motor is provided to the ecm via throttle control motor relay. 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. 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. P2102 description the throttle actuator is operated by the engine control module ecm and it opens and closes the throttle valve.
