Code P2112 Scion Description
The P2112 diagnostic trouble code (DTC) specifically applies to Scion vehicles and indicates that the Throttle Actuator Control System is stuck closed. This means that the electronic throttle control system, responsible for regulating the amount of air entering the engine, is not functioning properly and is stuck in a closed position. The throttle actuator control system is crucial for maintaining the proper balance of air and fuel in the engine, which directly impacts the vehicle's performance, fuel efficiency, and emissions.
Common Causes of P2112 Scion
- Faulty throttle body
- Malfunctioning throttle position sensor
- Wiring issues or electrical connections
- Powertrain control module (PCM) failure
- Environmental factors such as moisture or dirt affecting the throttle system
Symptoms of P2112 Scion
- Lack of power or acceleration
- Hesitation or stalling during acceleration
- Rough idling or engine misfires
- Reduced fuel efficiency
- Limp mode activation
How to Fix P2112 Scion
- Diagnose the issue using a diagnostic scanner to confirm the P2112 code and identify the specific component causing the problem.
- Inspect the throttle body, throttle position sensor, and related wiring for any signs of damage, wear, or corrosion.
- Clean or replace the throttle body if necessary, ensuring smooth operation of the throttle plate.
- Test the throttle position sensor for proper functionality and replace it if faulty.
- Reset the PCM and clear the DTC to see if the issue persists, ensuring all connections are secure and functioning correctly.
Cost to Fix P2112 Scion
