Because the exact location can vary slightly depending on the engine (2.2L or 2.4L), it's best to consult a repair manual specific to your Cavalier's year and engine. A Haynes or Chilton manual will have diagrams showing the sensor's location. You can also find diagrams online by searching for "[your engine code] 2001 Chevrolet Cavalier IAT sensor location".
Looking at diagrams or searching for photos online related to your specific engine will significantly improve your chances of finding it quickly.
