How do throttle position sensors (TPS) work?
As the throttle moves, a mechanical arm inside the TPS makes contact with points on a resistor strip.
What happens when contact is made?
Voltage is sent through the signal line to the Powertrain Control Module (PCM).
What causes a TPS to stop working?
A misadjusted TPS may result in poor idle, stalling,lack of power, and improper transmission shifting
Your Throttle Position Sensor Is Wearing Out
Throttle position sensors with a high failure rate that have been re-engineered for increased quality and longevity.
Most OE manufactures use a resistance type potentiometer circuit design in their throttle position sensors. This type of sensor circuit requires a circuit board with mechanical contacts to return a variable voltage signal. While this type of sensor operates effectively, the issue with this design is friction. Friction causes heat between the contacts as well as wear within the moving parts causing premature sensor failure. Our re-engineered sensors are a non-contact Hall effect design that eliminates the mechanical contact points. These sensors use an integrated non-contact circuit for more accurate and consistent electrical output which achieves a much greater performance and service life.
While physical dimensions and appearance remain similar in part applications and the replacement procedure does not differ between sensor types, circuit testing may require a different diagnostic method. Sensor testing with an ohm meter has not been the most effective way to test this sensor, monitoring voltage on the return circuit has always been the most effective test method and is the required test method on this improved circuit type.
Be sure to read and follow the replacement procedure from a repair resource as some vehicle applications may require a system calibration whenever the throttle position sensor is replaced.

Installed for my friend in his 02 jeep liberty, reset the system by removing the negative battery terminal then reinstalling n the problem was completely fixed, no more idle issues n stalling at stop lights

My 2003 liberty would start fine cold and idle to 1200, fine. However if i taped the throttle, it would jump up to about 1700 and stay there until the engine would fully warm up, so increased braking and wasting fuel. Plus this uses non contact hall circuits, no potentiometer to wear out. Simply put BUY IT! Schnecke is now my go to brand.
