Code P1124 2000 Ford F150 Description

The P1124 diagnostic trouble code (DTC) for a 2000 Ford F150 indicates that the Throttle Position Sensor (TPS) is out of self-test range. The TPS is a crucial component of the vehicle's electronic fuel injection system, as it monitors the position of the throttle valve and sends this information to the engine control module (ECM). This data is used by the ECM to calculate the appropriate air-fuel mixture for optimal engine performance and fuel efficiency.

Common Causes of P1124 2000 Ford F150

  1. Faulty TPS: The most common cause of this code is a malfunctioning Throttle Position Sensor. Over time, the TPS can wear out or become damaged, leading to inaccurate readings.
  2. Wiring issues: Corroded or damaged wiring connecting the TPS to the ECM can disrupt the signal transmission, causing the sensor to be out of self-test range.
  3. ECM malfunction: A problem with the engine control module itself can also trigger this code, as it may not be able to properly interpret the signals from the TPS.
  4. Throttle body issues: Carbon buildup or mechanical issues within the throttle body can affect the TPS readings, leading to the code being triggered.

Symptoms of P1124 2000 Ford F150

  1. Rough idling or stalling: The engine may idle erratically or stall frequently due to incorrect throttle position readings.
  2. Poor acceleration: The vehicle may experience hesitation or lack of power during acceleration, as the ECM may not be receiving accurate throttle position data.
  3. Decreased fuel efficiency: Incorrect throttle position readings can lead to inefficient fuel delivery, resulting in decreased fuel economy.
  4. Check Engine Light: The illumination of the Check Engine Light on the dashboard is a common symptom associated with this code.

How to Fix P1124 2000 Ford F150

  1. Diagnose the issue: Use a diagnostic scanner to retrieve the trouble code and perform a thorough inspection of the TPS, wiring, and related components.
  2. Replace the TPS: If the Throttle Position Sensor is found to be faulty, replace it with a new OEM or high-quality aftermarket sensor.
  3. Check wiring: Inspect the wiring harness for any signs of damage or corrosion, and repair or replace as necessary.
  4. Test and calibrate: After replacing the TPS, perform a calibration procedure to ensure proper functioning and accurate readings.
  5. Clear codes and test drive: Clear the DTC from the ECM memory, and test drive the vehicle to confirm that the issue has been resolved.

Cost to Fix P1124 2000 Ford F150

The typical repair costs for addressing a P1124 code on a 2000 Ford F150 can vary depending on the specific cause of the issue and the cost of parts and labor. On average, replacing a Throttle Position Sensor can cost between $50 and $200, while the labor cost for this repair can range from $50 to $150. Additional costs may apply if wiring repairs or ECM replacement is necessary. It's important to note that labor rates at auto repair shops can vary, so it's advisable to check with local shops for a more accurate estimate.

What does this mean?

Tech Notes for P1124 2000 Ford F150

The throttle position (TP) sensor circuit is monitored by the powertrain control module (PCM) for an out of range TP rotation angle or voltage input. The test fails if the TP rotation angle or voltage reading is less than 13.27% (0.66 volt) or greater than 23.52% (1.17 volts).

When is the Code Detected?

Engine Control Module (ECM) detected a Thottle Position (TP) sensor return voltage above or below expected value at an idle condition
