Do I need any gaskets or seals when installing this?

Sensor installation typically does not require additional gaskets — it threads directly into the factory location. If your old sensor has a crush washer that stayed behind, remove it before threading the new one in.

Will this work with my factory wiring harness?

Yes. This sensor uses the OEM connector, so it plugs straight into your existing harness with no splicing or adapters needed.

What if the sensor doesn't read correctly after install?

Double-check that the connector is fully seated and the sensor is threaded completely into the head. If codes persist, your engine control module may need a sensor reset — refer to your service manual or a qualified technician for diagnostics.
