Introduction
The electronic throttle control (ETC) system is a crucial component in modern vehicles like the Dodge Charger. It ensures smooth acceleration, precise throttle response, and overall engine performance. However, like any technological system, the ETC can sometimes malfunction, leaving you with a frustrating experience behind the wheel. If you’re facing issues with your Dodge Charger’s ETC, don’t panic. This comprehensive guide will provide you with a step-by-step approach to diagnose and fix the problem.

Understanding the ETC System
Before we delve into troubleshooting, let’s briefly understand how the ETC system operates. The ETC consists of sensors, actuators, and an electronic control unit (ECU). The position sensor monitors the throttle pedal movement, while the throttle body actuator adjusts the throttle valve opening based on the ECU’s commands. The ECU analyzes various engine parameters and adjusts the throttle position accordingly.
Symptoms of ETC Malfunction
Recognizing the signs of ETC malfunction is crucial. Common symptoms include:
- Rough idling or stalling
- Hesitation or jerking during acceleration
- Reduced engine power
- Check engine light illuminated
If you notice any of these symptoms, it’s essential to promptly diagnose and address the issue to prevent further damage to your vehicle.
Diagnosing the Problem
Start by connecting a diagnostic scan tool to your Dodge Charger. This will provide you with fault codes that can pinpoint the specific issue within the ETC system. Common fault codes include:
- P2112 – Throttle Position Sensor Circuit Low Input
- P2118 – Throttle Position Sensor/Switch D/E Voltage Correlation
- P2122 – Throttle/Pedal Position Sensor/Switch F Voltage Correlation
Once you have the fault codes, you can proceed with the next step.

Troubleshooting and Repair
Depending on the fault code displayed, here’s a troubleshooting guide to help you:
- P2112/P2118: Inspect the throttle position sensor for any damage or loose connections. Clean the sensor contacts if necessary. If the problem persists, the TPS may need replacement.
- P2122: This code indicates an issue with the throttle pedal assembly. Inspect the connections and wiring harness for damage. If the pedal or wiring harness is faulty, replacement is required.
In some cases, the ETC issue may not be related to sensor or actuator failure. Electrical problems, loose connections, or even software bugs can trigger ETC malfunctions. If the previous steps don’t resolve the problem, it’s best to consult a qualified mechanic for further diagnosis and repair.
Preventing ETC Issues
Regular vehicle maintenance is key to preventing ETC problems. Here are some preventive measures:
- Keep the engine clean and free of dirt or debris.
- Regularly inspect the throttle linkage and air filter for any signs of wear or damage.
- Avoid using low-quality fuel, as it can damage the fuel system and injectors, which can indirectly affect the ETC.
- Stay up-to-date with software updates for your vehicle’s ECU. These updates can often address bugs and improve the overall performance of the system.
