P2109 Ford Code - Throttle/Pedal Position Sensor 'A' Minimum Stop Performance

Quick Answer

The P2109 Ford diagnostic trouble code (DTC) indicates an issue with the Throttle/Pedal Position Sensor 'A' Minimum Stop Performance. Common causes include Faulty throttle position sensor: The sensor may be worn out, damaged, or malfunctioning, causing it to not reach its minimum stop position accurately, Faulty pedal position sensor: Similar to the TPS, the pedal position sensor may be faulty, leading to incorrect signals being sent to the ECM, Wiring or connector issues: Loose or damaged wiring connections between the sensors and the ECM can disrupt communication and cause this code to trigger. 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 P2109 Ford Description

The P2109 Ford diagnostic trouble code (DTC) indicates an issue with the Throttle/Pedal Position Sensor 'A' Minimum Stop Performance. This means that the Engine Control Module (ECM) has detected a problem with the throttle or pedal position sensor, specifically with the sensor's ability to reach its minimum stop position. The throttle position sensor (TPS) is responsible for monitoring the position of the throttle valve, which determines how much air enters the engine. The pedal position sensor, on the other hand, detects the position of the accelerator pedal and relays this information to the ECM to adjust the throttle accordingly.

Common Causes of P2109 Ford

  1. Faulty throttle position sensor: The sensor may be worn out, damaged, or malfunctioning, causing it to not reach its minimum stop position accurately.
  2. Faulty pedal position sensor: Similar to the TPS, the pedal position sensor may be faulty, leading to incorrect signals being sent to the ECM.
  3. Wiring or connector issues: Loose or damaged wiring connections between the sensors and the ECM can disrupt communication and cause this code to trigger.
  4. ECM malfunction: In some cases, the ECM itself may be malfunctioning, leading to incorrect sensor readings and triggering the P2109 code.
  5. Mechanical issues: Any mechanical issues with the throttle body, accelerator pedal, or related components can also affect the sensors' performance and trigger this code.

Symptoms of P2109 Ford

  1. Rough idling or unstable engine speed
  2. Hesitation or lack of response when pressing the accelerator pedal
  3. Engine stalling or cutting out unexpectedly
  4. Reduced fuel efficiency
  5. Illumination of the Check Engine Light

How to Fix P2109 Ford

  1. Diagnose the issue: Use a diagnostic scanner to read the code and pinpoint the exact cause of the problem.
  2. Inspect sensors and wiring: Check the throttle position sensor, pedal position sensor, and their wiring connections for any signs of damage or wear.
  3. Replace faulty sensors: If the sensors are found to be faulty, replace them with new ones to ensure accurate readings.
  4. Repair wiring or connectors: Repair any damaged wiring or connectors to ensure proper communication between the sensors and the ECM.
  5. Clear codes and test drive: Once the repair is completed, clear the codes from the ECM, and test drive the vehicle to ensure that the issue has been resolved.

Cost to Fix P2109 Ford

The cost of repairing the Throttle/Pedal Position Sensor 'A' Minimum Stop Performance issue can vary depending on the specific cause of the problem and the labor rates in your area. On average, the cost of replacing a throttle position sensor or pedal position sensor can range from $100 to $200 for the parts alone. Labor costs can add an additional $100 to $200, bringing the total repair cost to around $200 to $400. Keep in mind that these are rough estimates, and the actual cost may be higher or lower based on your vehicle's make and model, the severity of the issue, and the rates of the auto repair shop you choose. It's recommended to consult with a qualified mechanic for a more accurate cost estimate.
