Code P1124 1999 Ford F150 Description
The P1124 diagnostic trouble code (DTC) for a 1999 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). When the TPS is out of self-test range, it means that the sensor's signal is not within the expected parameters during the self-test procedure, which can lead to various performance issues.
Common Causes of P1124 1999 Ford F150
- Faulty Throttle Position Sensor.
- Wiring or connector issues.
- Dirty throttle body.
- Malfunctioning Engine Control Module.
- Incorrect TPS calibration.
Symptoms of P1124 1999 Ford F150
- Hesitation or lack of response when accelerating.
- Rough idling or stalling at idle.
