P2118 Throttle Actuator Control Motor Current Range Performance

P2118 is a diagnostic trouble code dtc for throttle actuator control motor current range performance.

P2118 throttle actuator control motor current range performance.

When the voltage becomes unstable the etcs itself becomes unstable. Code p2118 is set by the pcm when the throttle actuator control motor is out of range or not performing properly. 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. Obd ii fault code p2118 is a generic code that is defined as throttle actuator control tac throttle motor current range performance problem and is set when the pcm powertrain control module detects that the input voltage in the throttle control motor s control circuit falls outside of the expected desired range or that the throttle control motor does not perform as expected.

This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. 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. How to repair p2118 code throttle actuator control motor current range performance the throttle control motor is operated by the engine control module ecm and it opens and closes the throttle valve.
