P2103 Lexus Code - Throttle Actuator Control Motor Circuit High
Quick Answer
The Throttle Actuator is operated by the Engine Control Module (ECM) and opens and closes the throttle valve using gears. Common causes include Dirty throttle body, Faulty Throttle Actuator, Throttle Actuator harness is open. 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 P2103 Lexus Description
The opening angle of the throttle valve is detected by the throttle position sensor, which is mounted on the throttle with motor body assembly. The throttle position sensor provides feedback to the ECM. This feedback allows the ECM to appropriately control the throttle actuator and monitor the throttle opening angle as the ECM responds to driver inputs.
The ECM monitors the electrical current through the electronic actuator and detects malfunctions and open circuits in the throttle actuator based on this value. If the current is outside the standard range, the ECM determines that there is a malfunction in the throttle actuator. In addition, if the throttle valve does not function properly (for example, stuck on), the ECM determines that there is a malfunction. The ECM then illuminates the MIL and stores a Diagnostic Trouble Code (DTC).

- Dirty throttle body
- Faulty Throttle Actuator
- Throttle Actuator harness is open
- Throttle Actuator circuit poor electrical connection
