Code P1124 2001 Ford F150 Description

The OBD-II trouble code P1124 for a 2001 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 fuel injection system, as it monitors the throttle position and sends this information to the engine control module (ECM). The ECM uses this data to adjust the air-fuel mixture for optimal engine performance and efficiency. When the TPS is out of self-test range, it means that the signal being sent by the sensor is not within the expected parameters, leading to potential issues with engine performance.

Tech Notes for P1124 2001 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

Frequently Asked Questions about P1124 2001 Ford F150 Code

1. What does OBDII code P1124 mean on a 2001 Ford F150?

P1124 indicates that the Throttle Position Sensor (TPS) is reading values that are outside the expected range during a self-test.

2. What are the symptoms of code P1124 on a 2001 Ford F150?

Common symptoms include poor acceleration, rough idling, hesitation during throttle input, and a potential decrease in fuel efficiency.

3. What causes the P1124 code on a 2001 Ford F150?

The most common causes are a faulty Throttle Position Sensor, damaged wiring or connectors, or a misaligned throttle body.

4. Can I drive my 2001 Ford F150 with the P1124 code?

While it may be drivable, it’s not recommended as the vehicle could experience performance issues or enter limp mode, increasing the risk of further damage.

5. How can I fix the P1124 code on my 2001 Ford F150?

Start by inspecting the TPS and its wiring for damage, cleaning the throttle body, and replacing the TPS if necessary.

6. How do I test the Throttle Position Sensor on a 2001 Ford F150?

Use a multimeter to check the sensor's voltage range. It should increase smoothly as the throttle is opened. Irregular readings indicate a faulty sensor.

7. Can a dirty throttle body cause the P1124 code?

Yes, carbon buildup on the throttle body can disrupt the TPS readings and trigger the P1124 code.

8. Do I need to reprogram the ECU after replacing the TPS?

In most cases, the ECU will adjust automatically, but you may need to perform a throttle relearn procedure to ensure proper calibration.

9. What tools are needed to diagnose and fix code P1124 on a 2001 Ford F150?

You’ll need a multimeter, a scan tool or code reader, and basic hand tools like screwdrivers and sockets.

10. What happens if I ignore the P1124 code on my 2001 Ford F150?

Ignoring the code can lead to worsening performance, reduced fuel economy, and potential damage to other engine components.
