P0124 Dodge Code - Throttle Position Sensor/Accelerator Position Pedal Circuit Intermittent

Quick Answer

The P0124 diagnostic trouble code (DTC) for Dodge vehicles indicates an issue with the Throttle Position Sensor (TPS) or Accelerator Position Pedal Circuit being intermittent. Common causes include Faulty wiring connections: Loose or damaged wiring can disrupt the signal between the TPS and ECM, Defective TPS or accelerator pedal position sensor: A malfunctioning sensor can send incorrect signals to the ECM, causing performance issues, Corrosion in the circuit: Moisture and debris can accumulate in the circuit, leading to electrical problems. 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 P0124 Dodge Description

The P0124 diagnostic trouble code (DTC) for Dodge vehicles indicates an issue with the Throttle Position Sensor (TPS) or Accelerator Position Pedal Circuit being intermittent. The TPS is a crucial component of the engine management system, as it monitors the position of the throttle valve and sends signals to the Engine Control Module (ECM) to regulate fuel injection and ignition timing. The accelerator pedal position sensor works in conjunction with the TPS to ensure smooth and efficient engine operation.

Common Causes of P0124 Dodge

  1. Faulty wiring connections: Loose or damaged wiring can disrupt the signal between the TPS and ECM.
  2. Defective TPS or accelerator pedal position sensor: A malfunctioning sensor can send incorrect signals to the ECM, causing performance issues.
  3. Corrosion in the circuit: Moisture and debris can accumulate in the circuit, leading to electrical problems.
  4. Malfunctioning ECM: A faulty ECM can misinterpret sensor data and trigger the P0124 code.

Symptoms of P0124 Dodge

  1. Erratic throttle response: The vehicle may exhibit unpredictable acceleration patterns, making it difficult to maintain a steady speed.
  2. Poor fuel efficiency: A faulty TPS can result in incorrect fuel injection, leading to increased fuel consumption.
  3. Hesitation during acceleration: The engine may struggle to respond promptly when the accelerator pedal is pressed.
  4. Stalling: In severe cases, the engine may stall unexpectedly, especially at idle or during low-speed driving.

How to Fix P0124 Dodge

  1. Diagnose the issue: Use a diagnostic scan tool to retrieve the trouble code and perform a thorough inspection of the TPS, accelerator pedal position sensor, and related wiring.
  2. Test the sensors: Check the resistance and voltage output of the TPS and accelerator pedal position sensor to determine if they are functioning within specifications.
  3. Repair or replace faulty components: Repair any damaged wiring connections, clean corrosion from the circuit, and replace defective sensors as needed.
  4. Clear the trouble code: After making the necessary repairs, reset the ECM to clear the P0124 code and monitor the system for any recurring issues.
  5. Test drive the vehicle: Take the vehicle for a test drive to ensure that the throttle response is smooth and consistent, and that the symptoms associated with the P0124 code have been resolved.

Cost to Fix P0124 Dodge

The typical repair costs for addressing a P0124 code on a Dodge vehicle can range from $150 to $500, depending on the extent of the issue and the cost of parts and labor. Keep in mind that specific diagnosis time and labor rates at auto repair shops can vary based on location, vehicle make and model, and engine type. It's recommended to obtain quotes from multiple reputable shops to compare prices and ensure a fair estimate.
