What are the 3 wires in throttle positioning sensor?
The throttle position sensor (TPS) is a potentiometer located on the throttle body and attached to the throttle plate opposite the throttle linkage. It has three wires: battery voltage, 5-volt reference, and a signal wire.
How do I check my TPS wire?
To check it, touch the negative multimeter probe to the negative wire TPS tab and the positive problem to the positive tab. You should see around 5 volts on the multimeter if everything is working. Now, you should check the signal voltage.
How do I test my TPS with an ohm meter?

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.
What should TPS read at idle?
At idle is should be zero or a couple of degrees. Press down on the gas pedal very S-L-O-W-L-Y until the throttle is all the way open. You should see the percentage of throttle opening gradually increase to 100 percent at wide open throttle.
Why does the throttle position sensor Get Low voltage?
The voltage of the throttle position sensor can drop below the expected range for several reasons, including the following: A loosely-mounted throttle position sensor. Electrical short on the sensor circuit, either to the ground or to another wire. Faulty sensor.
Does TPS affect shifting?
The Throttle Position sensor measures the throttle position, which is controlled by the gas pedal. It is used to determine engine load and if it fails it can cause automatic transmission shifting problems.
