Solution

1. Preparation

• Gather tools and parts required for the repair.
• Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Inspect and Clean the IAT Sensor

• Locate the IAT sensor, typically found in the air intake duct or on the intake manifold.

• Clean the sensor using electrical contact cleaner and a soft cloth.
• Reinstall the sensor and reconnect the electrical connector.

3. Replace the IAT Sensor (if necessary)

• If the sensor is damaged or cleaning did not resolve the issue, replace it.
• Remove the old sensor as described in the previous step.
• Install the new IAT sensor and ensure it is tightened to the manufacturer's specifications (typically, torque to about 8-10 ft-lbs).
• Reconnect the electrical connector.

4. Clear Error Codes

• Reconnect the negative battery terminal.
• Use the OBD-II scanner to clear the P0113 code from the vehicle's computer.

5. Final Inspection

• Start the engine and allow it to reach normal operating temperature.
• Monitor the IAT readings with the scanner to ensure they are within normal parameters.
• Test drive the vehicle to confirm that the check engine light does not reappear and that performance is restored.
