1. Push the metal clip retainer and unplug.
2. Inspect the connector pins on both sides of the connection.
3. Reconnect and clear codes.
4. Drive the vehicle to see if the code returns or monitor the data for the intake air temp to see if it matches reality. Do the readings seem plausible. You will need a scantool that can read data or just drive it to see if the code returns.
