2.Locate the air intake assembly. It is usually a large tube or housing that carries air from the air filter to the throttle body.
3. Look for the IAT sensor near the throttle body. It is usually a small, cylindrical sensor with two wires
connected to it.
4. The sensor may be held in place by a screw or a plastic clip. Carefully remove the screw or release the clip to free the sensor.
5. Once the sensor is removed, you can inspect it for damage or contamination. If necessary, clean the sensor with a suitable solvent and reinstall it
