Code P1125 Ford Description

The P1125 Ford diagnostic trouble code relates to an issue with the throttle position sensor (TPS) intermittently sending incorrect signals to the engine control module (ECM). The TPS is a crucial component in the vehicle's fuel injection system, as it monitors the position of the throttle valve and sends this information to the ECM, which adjusts the air-fuel mixture accordingly. When the TPS fails to provide accurate data or sends intermittent signals, it can lead to drivability issues, reduced fuel efficiency, and overall poor engine performance.

  5. Engine going into limp mode

How to Fix P1125 Ford

  1. Diagnose the issue using a scan tool to confirm the P1125 Ford code and assess the TPS functionality.
  2. Inspect the TPS for wear, damage, or contamination, and replace if necessary.
  3. Check the sensor circuit for any electrical faults or loose connections, repairing or replacing components as needed.
  4. Test drive the vehicle after repairs to ensure the TPS is sending accurate signals and the code does not reappear.
  5. Clear the fault code from the ECM memory to complete the repair process.

Cost to Fix P1125 Ford

The typical repair costs for addressing a throttle position sensor intermittent issue can range from $150 to $300, including the cost of the sensor itself and labor charges. It's important to note that the specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. While most auto repair shops charge between $80 and $150 per hour, rates may be higher in metropolitan areas or at dealerships, while independent shops often offer more competitive pricing. To obtain a more accurate estimate, it is recommended to inquire about local rates before proceeding with the repair.
