This summary uses the existing diagnostic information shown in full below.
Your car's engine has a part called a throttle that helps control how fast the car goes. This code means there's a problem with the electric part that makes the throttle move. It's like when a toy car's remote control isn't working right.
The P2103 code indicates that the throttle actuator control motor circuit is experiencing a higher than expected voltage condition.
The throttle actuator is an electronic component that controls the throttle plate in the throttle body. When the engine control module (ECM) detects a high voltage condition in the throttle actuator control motor circuit, it triggers the P2103 code. This could mean that the motor is drawing too much current, or there is a short circuit in the wiring.
• Check Engine Light illuminated
• Reduced engine performance
• Unresponsive throttle
• Faulty throttle actuator control motor
• Short circuit in the wiring
• Faulty ECM
Throttle Actuator: An electronic device that controls the throttle plate.
ECM: Engine Control Module, the computer that manages engine functions.
• Use an OBD-II scanner to confirm the code.
• Inspect the throttle actuator wiring for damage or shorts.
• Test the throttle actuator motor for proper operation.
• Replace the throttle actuator control motor.
• Repair or replace damaged wiring.
• Replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Screwdriver set

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly inspect and maintain throttle body components.
• Ensure electrical connections are secure.
• Avoid exposure to moisture and contaminants.
Engine Performance
• Do not ignore the Check Engine Light.
• Seek professional diagnosis if unsure.
• Avoid driving aggressively until the issue is resolved.
Check your vehicle's warranty for coverage on electronic components.
This code has been more prevalent in vehicles with electronic throttle control systems introduced in the early 2000s.
Moderate – While the vehicle may still be drivable, it is important to address the issue to prevent further damage.
Driving with a malfunctioning throttle actuator can lead to reduced vehicle performance and safety risks.
• Engine running
• Throttle actuator engaged
The throttle actuator is located on the throttle body, which is typically mounted on the intake manifold.
Q: Can I drive my car with a P2103 code?
A: It's possible, but not recommended as it may lead to reduced performance and further damage.
Q: How do I reset the P2103 code?
A: After repairs, use an OBD-II scanner to clear the code from the ECM.
