However, the exact location can vary slightly depending on the specific model and trim level of your truck. It's best to:

1. Consult your owner's manual: This is the most reliable source for the precise location of sensors in your specific vehicle.

2. Use a repair manual or online diagrams: Websites like RepairPal or Haynes offer diagrams specific to your year, make, and model. Search for "2001 Chevy Silverado 4.3L IAT sensor location" (or "2001 Chevy S10 4.3L IAT sensor location" depending on your truck's model). These diagrams will show you exactly where it's located.

3. Visually inspect the intake tubing: Start at the air filter and follow the tubing towards the throttle body. The IAT sensor is likely somewhere along that path. It will be a small sensor with a wire connector.

Remember to be cautious when working near the engine and electrical components. If you're unsure about anything, it's best to consult a qualified mechanic.
