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.

Product description states this product will fit 2000-2004 Toyota Tacoma 3.4L V-6, but it does not fit. The OEM TPS is a 4-wire sensor and this product is a 3-wire sensor.

After doing extended research I opted to purchase this for my 1999 Toyota 4x4 with 3.4 engine.The main thing that prompted my choice was my truck was listed on the sellers specs, The other sellers I considered didn't list my exact model or specs.Having said all that, the dreadful check engine light has disappeared!Thanks to the seller!

Not exactly OEM but it worked for me, been doing fine for 5000 miles now.
