Your vehicle's throttle position sensor is a sensor that is connected to the butterfly spindle and is primarily used to monitor the throttle position within an inner combustion engine. Due to its location, the throttle position sensor is able to effectively observe where the throttle butterfly valve is positioned. There are currently three different designs of the throttle position sensor - switch, potentiometer and combination. The switch design allows for it to be on while the throttle is closed but off when the vehicle is idling. The potentiometer design allows for, depending on the location of the valve and throttle position, a variable resistance. The combination design is ultimately a blend of the two designs listed above. The throttle position sensor is a sensor that synchronizes with the ECU - engine control unit - in order to make certain that the vehicle has an efficiently working throttle. Your throttle needs to be in proper working order at all times as it is a major component in the functioning of your vehicle. When the throttle valve on your vehicle is open or even closed, data, or a signal, is transmitted to your vehicle's ECU. This data is then used to assist in providing a swift reaction when the used fuel amount needs to change. As an example, if you have an engine that is fuel injected and the throttle is opened wide and rapid then extra fuel will likely be injected in order to avoid the stalling of your vehicle. Depending upon the throttle's position, the fuel injection timing and ignition timing will alter. Since the throttle position sensor is so important, you need to know when you may have a bad one. Your vehicle could begin stalling after you start it or it could possibly idle rough. Sometimes you may actually hear a slight ping within your engine. Any of these are signs of bad adjustment of your throttle position sensor and it should be checked out immediately.

The Beck Arnley Throttle Position Sensor reads data concerning the flat valve in the throttle inside the vehicle's motor and submits it to the on-board computer.


The Bosch Throttle Position Sensor monitors readings about the positioning of the valve called a 'butterfly valve' inside the car's engine and sends it to the electric control unit.


The Delphi Throttle Position Sensor reads data concerning the positioning of the flat valve in the throttle inside the vehicle's engine and relays it to the on-board electric control unit.


The car's Denso Throttle Position Sensor applies different amounts of resistance to the butterfly valve, which lets it check the valve angle with great precision.


The Dorma Throttle Position Sensor is on the engine and is usually situated on the spindle that holds the butterfly valve so it can easily scan the angle of the throttle valve.


The Hella Throttle Position Sensor scans information concerning the positioning of the valve called a 'butterfly valve' inside the car's motor and relays it to the on-board ECU.

Your automobile's Mopar Throttle Position Sensor transmits variable amounts of resistance to the throttle valve, which lets it monitor the valve position with great accuracy.


The car's Motorcraft Throttle Position Sensor provides variable amounts of resistance to the butterfly valve, which allows it to test the valve position with accuracy.


The Standard Throttle Position Sensor is on the motor and is normally located on the spindle that holds the butterfly valve so it can easily register slant of the throttle valve.

Throttle Position Sensor
You know that your vehicle needs fuel in order to power the engine, but you may not give much thought to the intricate process that takes place within your vehicle's internal combustion engine when it comes to the air-fuel mixture. Your engine has to have the correct mix of air and fuel at all times, in order to run properly. The throttle position sensor is part of your vehicle's fuel management system, and without it, your engine's air-fuel mixture wouldn't be properly regulated. If the engine TPS fails, you'll need to replace it promptly.
If you need a new throttle position sensor, PartsGeek.com has got you covered. We carry leading names in engine TPS, such as Standard Motor Products, Beck Arnley, Dorman, Genuine, Original Equipment, Delphi, Motorcraft, Bosch, Auto 7, Mopar, Walker and Denso. If you happen to order the wrong part by mistake, you can send it back with our 30-day return policy, because we want to make sure you get exactly what you need for your vehicle.
What is a throttle position sensor?
A throttle position sensor is, by definition, the part on your vehicle that determines the position of the throttle. Your vehicle's fuel injection system needs to monitor the engine's power needs in order to determine how much fuel is needed to power the vehicle. The data that comes from the engine TPS is combined with other factors such as air mass flow and the rate of change in the throttle position, as well as the air temperature and engine RPM, to determine how much fuel to inject into the engine. If this part is no longer working properly, it can't provide the right information to the fuel injection system about how much fuel to provide to the engine, which often leads to problems with acceleration or stalling out.
How much is an engine TPS?
The vast majority of throttle position sensors cost between $50 and $100. However, if your engine is particularly large, such as a V6, or a diesel fuel engine, the engine TPS may cost as much as $200 or more. The price for the right throttle position sensor for your vehicle depends on the engine itself. Browse the PartsGeek.com catalog of parts to determine the exact price for your car or truck.
What happens if a throttle position sensor fails?
There are several signs that the engine TPS may need to be replaced. Since this part helps the vehicle's fuel injection system to regulate the fuel mixture in your car or truck, one of the first signs that it's no longer working properly is if your car or truck has trouble accelerating. Sometimes the vehicle may even accelerate by itself, because the sensor is no longer accurately detecting the position of the throttle.
Other signs of potential problems with the throttle position sensor include stalling, rough idling, loss of power, inability to reach high speeds, or engine misfiring. Although less specific in nature, if the check engine light comes on, this could also be your vehicle's way of alerting you to the fact that the engine TPS needs to be checked or replaced.
