The throttle position sensor mounted on the throttle body of a 1995 Chevrolet Silverado is used by the computer to determine how much air is coming into the engine. In turn, it adjusts the fuel going into the engine accordingly, to achieve a perfect air to fuel ratio. When this sensor fails, the computer won't know how to properly tune the engine, and will run poorly because of it. To fix the problem, you have to replace the sensor with a new one.
Pop the hood. Remove the air filter from the top of the engine using your hands to take off the wing nut holding it to the throttle body. Locate the throttle position sensor on the passenger side of the throttle body and disconnect the electrical connection to it using your hands.
Remove the sensor from the throttle body using the torx-head driver. Twist it out of the throttle body and remove the sensor and the seal.
Place the replacement throttle position sensor seal onto the throttle body. Install the throttle position sensor and then twist it 90 degrees to lock it into the mounting screws. Bolt it in place using the torx-head driver. Plug it back in place and reinstall the air cleaner.
