Installation Notes and Tips

Use the complete assembly when the housing, connector area, or air tube condition needs to be addressed at the same time as the sensor. Handle the sensing element carefully and avoid touching it with bare hands. Confirm connector shape, terminal count, and vehicle application before installation. For Hyundai Elantra, Hyundai Kona, and Hyundai Sonata service, verify the existing unit matches the complete assembly configuration.
