Throttle actuator control motor circuit low.

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. 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. The throttle actuator is operated by the engine control module ecm and it opens and closes the throttle valve. 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.

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 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. To help determining whether the throttle valve control motor is functioning correctly different deviations from the example signal are mentioned along with possible causes. P2102 throttle actuator control motor circuit low.

What does that mean. The throttle control motor relay is on off controlled by the ecm. It s a long story but i will try to make it short and simple. The signal from the actuator is shown and can be downloaded.

When the pcm receives the input it will change the signals to the throttle actuator. Power supply for the throttle control motor is provided to the ecm via throttle control motor relay. Power supply for the throttle control. Throttle actuator control motor circuit open tacm what the p2100 code means.

With a lab scope a throttle valve control motor signal voltage is measured with the key on and engine off. P2118 toyota description the electronic throttle control system etcs has a dedicated power supply circuit.
