Code P1125 2001 Ford F150 Description

The Throttle Position Sensor (TPS) responds to the accelerator pedal movement. The TPS is a rotary potentiometer sensor that provides a signal to the Powertrain Control Module (PCM) that is linearly proportional to the throttle plate/shaft position. As the TPS is rotated by the throttle shaft, the following operating conditions are determined by the PCM:
• Closed throttle (includes idle or deceleration)
• Part throttle (includes cruise or moderate acceleration)
• Wide open throttle (includes maximum acceleration or de-choke on crank)
• Throttle angle rate

Code Tech Notes

The TP sensor circuit is monitored by the PCM for sudden TP rotation angle (or voltage) input change through the comprehensive component monitor (CCM). If during the last 80 warm-up cycles in key ON engine running the PCM detects a TP rotation angle (or voltage) changes beyond the minimum or maximum calibrated limit, a continuous diagnostic trouble code (DTC) is stored.

What is the Cost to Diagnose the Code?

Labor: 1.0

To diagnose the P1125 2001 Ford F150 code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about P1125 2001 Ford F150 Code

1. What are the common symptoms of an intermittent throttle position sensor (TPS) on a 2001 Ford F150 with OBDII code P1125?

- Common symptoms include erratic engine idling, stalling, hesitation during acceleration, poor fuel efficiency, and potentially triggering the check engine light.

2. What are the possible causes of an intermittent throttle position sensor issue triggering OBDII code P1125 on a 2001 Ford F150?

- Possible causes include a faulty TPS sensor, wiring issues, poor electrical connections, or a dirty throttle body affecting sensor readings.

3. How can I diagnose an intermittent throttle position sensor problem on my 2001 Ford F150 with OBDII code P1125?

- You can diagnose the issue by performing a visual inspection of the TPS and related wiring, conducting a TPS sensor test using a multimeter, and checking for any stored trouble codes.

4. Is it safe to continue driving my 2001 Ford F150 with an intermittent throttle position sensor issue and OBDII code P1125?

- It is not recommended to drive the vehicle with a faulty TPS, as it can lead to unpredictable engine behavior and potentially unsafe driving conditions.

5. Can I clean the throttle position sensor to resolve the intermittent issue on my 2001 Ford F150 with OBDII code P1125?

- Cleaning the TPS and throttle body may help resolve minor issues caused by dirt or debris, but if the problem persists, it is advisable to replace the TPS sensor.

6. How much does it typically cost to repair or replace a throttle position sensor on a 2001 Ford F150 with OBDII code P1125?

- The cost of replacing a throttle position sensor can vary depending on the labor rates and parts costs, but it typically ranges from $100 to $300 for parts and labor.

7. Are there any DIY tips for fixing an intermittent throttle position sensor issue triggering OBDII code P1125 on a 2001 Ford F150?

- DIY tips include ensuring proper wiring connections, cleaning the TPS and throttle body, and following manufacturer guidelines for TPS sensor testing and replacement.

8. Will resetting the OBDII code P1125 on my 2001 Ford F150 eliminate the intermittent throttle position sensor issue?

- Resetting the code may temporarily clear the check engine light, but if the underlying issue with the TPS sensor persists, the code is likely to reappear.

9. Can a mechanic use a scan tool to pinpoint the exact cause of the intermittent throttle position sensor issue on my 2001 Ford F150 with OBDII code P1125?

- Yes, a mechanic can use a scan tool to access live data from the TPS sensor, check for any underlying issues, and accurately diagnose the problem.

10. How often should I have the throttle position sensor inspected or replaced on my 2001 Ford F150 to prevent intermittent issues and OBDII code P1125?

- It is recommended to have the TPS sensor inspected during regular maintenance intervals or if you experience any symptoms of a failing sensor to prevent intermittent issues and potential OBDII codes like P1125.
