Throttle position sensor resistance test

Suspect a faulty throttle position sensor for engine problems? Look no further. In this video I will explain how a (TPS) Throttle Position Sensor works, how. The throttle position sensor is a power resistor located on the throttle body, and it carries out the function it has the purpose of feeding data to your engine control unit despite the level at which the throttle valve is open Slowly, move the throttle through its full range of movement from its closed position to its full open position, while observing the digital readout on the DMM. It should increase or decrease steadily and evenly as the throttle linkage is moved through its full range The type of multimeter that you'll need to resistance test Throttle Position (TP) Sensor 1 and Sensor 2 is important. You need to use a digital multimeter with a bar graph or an analog multimeter (this is a multimeter with a needle). The digital multimeter with a bar graph simulates the needle of the analog multimeter the resistant range they give of 3.5 - 6.5 kilo-ohms is between pins 1 and 2, and is just a general check to see if the value falls within that range, the second test where you move the throttle and look for a change is between pins 2 and 3. They don't seem to give the ranges for that test, but they indicate the resistance should change smoothly

With the car completely warmed up and the engine off, unplug the TPS connector then set your multimeter to test for resistance. Connecting between terminals A and B, you should find 1K ohms with the throttle in the idle position, untouched. Opening the throttle completely, you should have 5K ohms, plus or minus 1K Throttle position sensor resistance test #2 - YouTube: Disclaimer.
