P2118 is a diagnostic trouble code dtc for throttle actuator control motor current range performance.
P2118 throttle actuator control motor current range performance.
There are six codes that are associated with throttle actuator control system malfunctions and they are p2107 p2108 p2111 p2112 p2118 and p2119.
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.
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.
Error code p2118 is defined as throttle actuator control motor current range performance which usually happens due to wiring or throttle motor issue.
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.
This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
