How to troubleshoot the Throttle Position Sensor (TPS) on Ford Explorer Sport Trac?

Before deciding that sensor failure has occurred, it is necessary to inspect wiring problems when troubleshooting the Throttle Position Sensor (TPS). The TPS is a potentiometer on the throttle body that sends throttle position to the PCM through a voltage signal. Surging or stalling may result from a faulty TPS. To test the TPS, disconnect the sensor and check the reference voltage, which should be around 5.0 volts with the ignition On and the engine off. Reconnect the sensor and measure the signal voltage, which should be 0.5 to 1.5 volts at closed throttle and increase steadily to 4.0 to 5.0 volts at wide-open throttle. Ensure that when closed, the meter reads less than 1.5 volts, and when fully open it gives about 5.0 volts reading on the multimeter display. There can be a need for advanced tests if those issues continue happening in your car engine system or have some effect on vehicle performance. Remove the snow shield (on 2001 and later models) to replace the non-adjustable TPS. Then, disconnect the electrical connector before firmly attaching the new sensor on the throttle body.

Ford Explorer Sport Trac Throttle Position Sensor

The Throttle Position Sensor or the TPS is very essential with the Ford Explorer Sport Trac in its fuel control wherein series of signals are being relayed back by the TPS concerning the position of the throttle to ideally mix the fuel and air for combustion. In the electronic throttle control system, TPS is connected to the computer of the engine in order to find the quantity of fuel to be supplied in comparison to the air intake. Other forms of TPS include the Closed Throttle Position Sensor otherwise known as the CTPS to show that the throttle is closed fully. Recent TPS employ contactless measurement techniques such current standoff sensors like the Hall effect or magnetoresistive sensors in contrast to the potentiometer ones. When it comes to the broader picture, the TPS and allied accelerator pedal sensors play an interrelated role in the efficiently well-working and performance of Ford Explorer Sport Trac vehicles.
