Code P2118 2007 Toyota Highlander Description

The P2118 diagnostic trouble code (DTC) for a 2007 Toyota Highlander relates to the Throttle Actuator Control Motor Current Range/Performance. This code indicates that the Engine Control Module (ECM) has detected an issue with the throttle actuator control motor current falling outside of the expected range. The throttle actuator control motor is responsible for controlling the opening and closing of the throttle plate, which regulates the amount of air entering the engine. This, in turn, affects the engine's performance and fuel efficiency.
