* In the intake tube: This is the most common location. The IAT sensor is a small, usually black, cylindrical sensor embedded within the intake air tube. The tube is the path that air takes from the air filter box to the throttle body. Look closely at the tube; the sensor might be readily visible or might require some maneuvering to see.
* Integrated into the mass airflow sensor (MAF): Some GM vehicles have the IAT sensor built directly into the MAF sensor housing. The MAF sensor is typically located in the intake tube, near the air filter box. If this is the case, you won't find a separate IAT sensor.
To find it:
1. Locate the air filter box: This is usually a large rectangular plastic box under the hood.
2. Follow the intake tube: The intake tube runs from the air filter box towards the throttle body (the large butterfly valve at the engine's intake).
3. Inspect the tube carefully: Look for a small, cylindrical sensor plugged into the tube. It might have a wire harness connected to it.
4. Check the MAF sensor: If you don't find a separate sensor, examine the MAF sensor itself – it might house the IAT sensor.
Caution: Always disconnect the negative battery terminal before working near any electrical components to prevent accidental shorts or damage. If you're unsure of any step, consult a repair manual specific to your 2000 Chevy Silverado 5.3L. A repair manual will provide diagrams and detailed location information.
