Code P2123 Dodge Description
The P2123 code for Dodge vehicles indicates an issue with the Throttle Actuator Control (TAC) system, specifically related to the motor current range/performance. The TAC system is responsible for regulating the throttle opening in response to the driver's input. When this code is triggered, it means that the Engine Control Module (ECM) has detected a problem with the current flowing through the throttle actuator control motor, which could lead to improper throttle response and affect the vehicle's performance.
Common Causes of P2123 Dodge
- Faulty throttle actuator control motor.
- Wiring issues or poor connections.
- Faulty throttle position sensor.
- Malfunctioning ECM.
- Electronic throttle control system failure.
Symptoms of P2123 Dodge
- Lack of power or hesitation when accelerating.
- Rough idling or engine stalling.
- Vehicle going into limp mode.
- Illumination of the check engine light.
- Decreased fuel efficiency.
How to Fix P2123 Dodge
- Begin by conducting a thorough inspection of the throttle actuator control motor, wiring, and connections for any signs of damage or wear.
- Test the throttle position sensor to ensure it is functioning correctly.
- Check the ECM for any fault codes and perform any necessary reprogramming or replacement.
- Clear the code from the ECM and reset the system to see if the issue persists.
- If necessary, replace the throttle actuator control motor or any other faulty components identified during the diagnostic process.
