2000 Chevrolet Silverado Install Throttle Position Sensor
The throttle position sensor (TPS) on a 2000 Chevrolet Silverado is controlled by the throttle body butterfly. It determines how open the throttle is at any point and delivers that information to the computer. In turn, the computer determines if it needs to adjust the fuel delivery accordingly. If it breaks, the Silverado's engine will run poorly and idle rough. Fixing the problem is as simple as replacing the old TPS with a new one. Once you have the old one out, you'll have to install the new one, which takes about 15 minutes.

Install Throttle Position Sensor
- Install a replacement o-ring onto the TPS by hand. Align the TPS with the throttle shaft on the throttle body and bolt it in place using the 1/4-inch ratchet and socket. Plug in the wiring to the sensor.
- Reinstall the alternator in the alternator bracket using the 3/8-inch ratchet and socket. Reconnect the electrical connections on the alternator with an open-end wrench.
- Put the breaker bar on the tensioner at the top of the alternator. Turn the tensioner clockwise and pull the serpentine belt around the alternator pulley, then release the tensioner. Reinstall the positive terminal on the battery using an open-end wrench, then follow with the negative terminal.
