Where is throttle position sensor on 2004 silverado?

The throttle position sensor (TPS) on a 2004 Chevrolet Silverado is located on the throttle body. The throttle body is connected to the engine and controls the amount of air that flows into it. The TPS is a sensor that measures the position of the throttle valve and sends this information to the engine control unit (ECU). The ECU then uses this information to calculate how much fuel to inject into the engine.

To locate the TPS on your 2004 Silverado, follow these steps:

1. Open the hood of your vehicle.

2. Locate the throttle body. It is usually located on the front of the engine, near the top.

3. The TPS is attached to the side of the throttle body. It is a small, black sensor with a single wire connector.

If you are having problems with your vehicle's idle or acceleration, the TPS may be the cause. You can test the TPS by using a multimeter to measure the voltage at the sensor. The voltage should change as you move the throttle valve. If the voltage does not change, the TPS may be faulty and need to be replaced.
