Code P2118 Description

The P2118 code indicates a problem with the Throttle Actuator Control Motor's current range or performance. The throttle actuator control motor is responsible for controlling the throttle plate angle in response to driver input through the gas pedal. This code typically means that the current flowing through the throttle actuator motor is not within the expected range, which can lead to issues with throttle response and overall engine performance. If left unaddressed, this issue can result in reduced fuel efficiency, drivability problems, and potential damage to other engine components.
