What is the throttle position sensor on a Ford F-150?
This article applies to the Ford F-150 (2004-2014) and F-250, F-350 Super Duty (2005-2014). A TPS is the throttle position sensor that gives information to the computer of your F-150 or Super Duty on the position of a car's throttle.
Where is the throttle position sensor on a car?
The throttle position sensor keeps constant tabs on the butterfly valve position and reports it back to the engine management system in the powertrain control module. Because of where it’s located, it’s sometimes simply called a throttle body sensor.
What are the symptoms of a throttle position sensor defect?
The appearance of these symptoms has a chance of throttle position sensor defect. Another symptom appears if the TSP defects present as the stalling, poor idling, and engine misfires after the truck stops.
How to replace the throttle body TPS sensor?
Make sure to remove the TPS sensor and 2 screws that connect to bottom of throttle body. Once the old sensor is off, replace it with the new one. Clean the throttle body really well, then install it back by reversing the steps above. When taking off the accelerator cable with the screw driver, remove it softly to avoid breaking the clips.

Does a throttle position sensor need to be programmed?
Code errors can cause your throttle position sensor to work erratically or incorrectly. Otherwise, you'll need professional software to reprogram your sensor. This job is best done by a professional mechanic.
What happens if TPS is not calibrated?
If your TPS is faulty or uncalibrated, the sensor will be unable to accurately determine the position of the sensor. This will lead to a variety of symptoms, all of which are caused by the fact that the ECM is delivering the wrong air/fuel ratio to the cylinders thanks to the bad sensor.
How do you test a throttle position sensor?
Test the TPS using a digital multimeter. Make sure that it's still working and, if necessary, visually inspect and test the wires and connector. If the sensor tests OK, erase the code. If it comes back or you notice a performance issue.

What does the throttle position sensor do?
A throttle position sensor is used to measure how open the throttle valve is and therefore controls the amount of air which can flow into the engines intake manifold.
How much does it cost to replace a throttle position sensor on a F150?
The average cost for replacement $120-$210, the new one is around $18 to $49.
How many volts does a TPS sensor have?
The voltage during TPS closeness and its wide opening is around 9v and 4 volts. It will appear on your sensor computer screen. In both throttle conditions, the voltage goes increasing.
What is a TPS sensor?
TPS is also called a throttle position sensor potentiometer in which the sensor has a direct connection with the PCM. It provides a small voltage to PCM, which changes with throttle body position. Sometimes TPS gives a signal which diagnoses the detector system.
What size bolts are compatible with TPS?
You can get the new bolts of correspondence size with almost 10-15mm in size. Now, mounting the sensor on its position and put back the screws and tighten them with a ratchet and make it firm.
Why does my TSP fail?
The TSP failure may also occur due to low power produce acceleration but not speed up to its original exceed limit. After putting the pedal pressure, the acceleration develops but cannot speed up almost 15-30MPH with less power. When any defect occurs in your truck, it means the check engine light turns on.
What does it mean when the check engine light turns on?
When any defect occurs in your truck, it means the check engine light turns on. Sometimes it may not happen because it can also illuminate when other engine system defects develop. If other symptoms figure out first, then check your truck’s TSP system and try to repair it as soon as possible.
What is TPS signal?
It gives the engine power according to demand and signal to the fuel injection system. The TPS signals are compatible with various parameters like air temperature, throttle position change, and engine RPM.
How does the throttle plate work?
Once you step on the accelerator pedal, the throttle plate opens and since the TPS is connected to the throttle, it starts to measure how much it opens. When the throttle plate opens, the voltage increases. When the throttle plate closes, the voltage decreases. The ECM is then fed this changing voltage.
What does it mean when TPS fails?
The one thing that you can definitely count on, when the TPS fails, is the check engine light shining nice and bright to let you know that there's a Diagnostic Trouble Code stored in the fuel injection computer. Here are some specific symptoms you'll see:
Can OBD I diagnostic trouble codes be read?
A generic scan tool that can read OBD I diagnostic trouble codes does come in handy, but the scan tool won't help you test the TPS and therefore you won't need it to use the test info in this tutorial (the test in this tutorial will help you test the TPS without a scan tool).
What is TPS in a car?
Your TPS supplies information to your vehicle's computer about the throttle position-specifically, its relative position to the throttle body-which guarantees a smooth-running ride since the proper amount of air is entering your engine.
Can a TPS stall if throttle is closed?
A faulty TPS also doesn't know if the throttle is completely closed when your vehicle is idling. And, with a malfunctioning TPS, your engine can stall abruptly at any time, since your ride's on-board computer can't guide the engine to function optimally.
