P2104 Dodge Code - Throttle Actuator Control System - Forced Engine Idle
Quick Answer
The P2104 diagnostic trouble code (DTC) for Dodge vehicles refers to a problem with the Throttle Actuator Control System that leads to a forced engine idle condition. Common causes include Faulty throttle body: The throttle body may be dirty, worn, or malfunctioning, causing issues with the throttle actuator control system, Throttle position sensor failure: The throttle position sensor may fail, leading to incorrect throttle position readings and triggering the P2104 code, Wiring or connector issues: Loose or damaged wiring or connectors in the throttle actuator control system can disrupt communication between components. 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 P2104 Dodge Description
The P2104 diagnostic trouble code (DTC) for Dodge vehicles refers to a problem with the Throttle Actuator Control System that leads to a forced engine idle condition. This code indicates that the Engine Control Module (ECM) has detected an issue with the electronic throttle control system, specifically with the throttle actuator control. The throttle actuator control system is responsible for managing the opening and closing of the throttle valve to regulate the airflow into the engine, which in turn controls the engine speed. When this system malfunctions and forces the engine into idle mode, it can lead to a variety of performance issues and potentially hazardous driving conditions.
Common Causes of P2104 Dodge
- Faulty throttle body: The throttle body may be dirty, worn, or malfunctioning, causing issues with the throttle actuator control system.
- Throttle position sensor failure: The throttle position sensor may fail, leading to incorrect throttle position readings and triggering the P2104 code.
- Wiring or connector issues: Loose or damaged wiring or connectors in the throttle actuator control system can disrupt communication between components.
- ECM malfunction: A malfunctioning ECM can misinterpret signals from the throttle position sensor, leading to an incorrect throttle opening.
Symptoms of P2104 Dodge
- Loss of power: The vehicle may struggle to accelerate or maintain speed due to limited throttle response.
- Rough idle: The engine may run erratically at idle, causing vibrations and instability.
- Hesitation or stalling: The engine may hesitate or stall when accelerating or decelerating.
- Check Engine Light: The dashboard may display warning lights, such as the Check Engine Light, indicating a problem with the throttle actuator control system.
How to Fix P2104 Dodge
- Diagnose the issue: Use a professional OBD-II scanner to read the trouble codes and perform a thorough inspection of the throttle actuator control system to identify the root cause of the problem.
- Clean or replace the throttle body: Clean the throttle body to remove any dirt or debris that may be affecting its operation. If cleaning does not resolve the issue, consider replacing the throttle body.
- Test and replace sensors: Test the throttle position sensor and accelerator pedal position sensor to ensure they are functioning properly. Replace any faulty sensors as needed.
- Check wiring and connectors: Inspect the wiring and connectors in the throttle actuator control system for damage or corrosion. Repair or replace any damaged components to restore proper functionality.
- Reset the ECM: After completing the repairs, reset the ECM to clear the trouble codes and relearn the throttle position for optimal performance.
Cost to Fix P2104 Dodge
The typical repair costs for addressing the P2104 code on a Dodge vehicle can range from $200 to $500, depending on the specific components that need to be repaired or replaced. This estimate includes the cost of parts and labor, which can vary depending on the shop rates and the complexity of the repair. It's important to note that the cost may be higher if multiple components need to be replaced or if additional diagnosis and testing are required. It is recommended to consult with a qualified mechanic or auto repair shop for a more accurate cost estimate based on the specific vehicle make and model.
