Throttle Actuator Control Motor Circuit

The throttle actuator control motor is used on cars with electronically controlled throttle bodies also called drive by wire.

Throttle actuator control motor circuit.

P2103 throttle actuator a control motor circuit high code severity symptoms severity is usually severe due to its impact on the cooling system. Obd ii fault code p2100 is a generic code that is defined as throttle actuator control tac motor control circuit or sometimes as throttle actuator control tac motor control circuit open and is set when the pcm powertrain control module detects an open circuit in the control system of the throttle actuator motor s control circuit s. What causes the p2100 code. When the driver presses the accelerator pedal the accelerator pedal position sensor app sends a signal to the engine s control module pcm telling the pcm how much power the.

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. Because this can be either an electrical or mechanical failure the pcm cannot fully compensate for it. On these systems the gas pedal is a sensor that sends a signal to the throttle actuator control motor which opens and closes the throttle plate according to demand. The electronic throttle control system etcs controls the throttle valve opening.

Power supply for the throttle control motor is provided to the ecm via the throttle control motor relay. Throttle actuator control motor circuit open tacm what the p2100 code means. Obd ii code p2100 is defined as a throttle actuator a control motor circuit open. Error code p2101 is defined as throttle actuator control motor circuit range performance.

The throttle actuator will not work. 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 error code is a generic trouble code meaning it applies to all vehicles equipped with obd ii system especially those made since 1996 up to present. The throttle actuator is operated by the engine control module ecm and it opens and closes the throttle valve.
