Clean and Deoxidize the Throttle Body Electrical Connector

1. Ensure the ignition is switched to the OFF position.

2. Unclip and remove the 10-pin wiring harness connector from the throttle body.

3. Inspect the pins on both the harness and the throttle body side for signs of oxidation, green corrosion, or bent terminals.

4. Spray both sides of the connector with high-quality electronic contact cleaner and allow it to dry completely.

5. Apply a small amount of dielectric grease to the connector pins to prevent future moisture ingress and oxidation.

6. Firmly reconnect the harness until the locking tab clicks into place.

7. Perform a test drive while monitoring live data via diagnostic software to ensure the signal dropouts are resolved.
