P2118 Lexus Code - Throttle Actuator Control Motor Current Range / Performance
Quick Answer
The P2118 diagnostic trouble code for Lexus vehicles indicates an issue with the Throttle Actuator Control Motor Current Range or Performance. Common causes include Faulty throttle actuator control motor: The motor itself may be malfunctioning, causing erratic current flow and performance issues, Wiring or connector issues: Poor connections or damaged wiring leading to the throttle actuator control motor can cause irregular current flow, Electronic control module (ECM) failure: A failure in the ECM, which controls the throttle actuator motor, can lead to performance issues. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2118 Lexus Description
The P2118 diagnostic trouble code for Lexus vehicles indicates an issue with the Throttle Actuator Control Motor Current Range or Performance. This code typically means that the current flowing through the throttle actuator control motor is outside of the expected range, which can lead to poor performance and drivability issues. The throttle actuator control motor is responsible for controlling the opening and closing of the throttle valve, which regulates the amount of air entering the engine. When this motor is not functioning properly, it can impact the engine's performance, fuel efficiency, and overall drivability.
Common Causes of P2118 Lexus
- Faulty throttle actuator control motor: The motor itself may be malfunctioning, causing erratic current flow and performance issues.
- Wiring or connector issues: Poor connections or damaged wiring leading to the throttle actuator control motor can cause irregular current flow.
- Electronic control module (ECM) failure: A failure in the ECM, which controls the throttle actuator motor, can lead to performance issues.
- Throttle body issues: Problems with the throttle body, such as carbon buildup or mechanical faults, can affect the motor's performance.
Symptoms of P2118 Lexus
- Loss of power: The vehicle may experience a lack of power or acceleration when the throttle is applied.
- Rough idle: The engine may idle roughly or inconsistently, leading to a shaky or unstable driving experience.
- Stalling: The engine may stall or shut off unexpectedly, especially when coming to a stop or idling.
- Reduced fuel efficiency: The vehicle may consume more fuel than usual due to improper throttle control.
- Check Engine Light: The Check Engine Light may illuminate on the dashboard, indicating a potential issue with the throttle actuator control motor.
How to Fix P2118 Lexus
- Diagnose the issue: Use a diagnostic scanner to read the trouble code and perform further testing to pinpoint the exact cause of the problem.
