Does this sensor plug directly into the factory harness?

Yes. This is a direct OEM replacement that connects to the factory oxygen sensor connector without adapters or splicing.

Do I need to clear the check engine light myself after installation?

Once the new sensor is installed and the vehicle runs a full cycle, the diagnostic codes should clear automatically. If the light persists, have the system scanned to confirm the sensor is reading correctly.

What tools do I need to swap this out?

A basic socket wrench and oxygen sensor socket (if available) make removal easier. The sensor is accessible from under the vehicle — refer to your service manual for the exact location and torque spec.
