Installation Notes and Tips

Verify connector style, terminal count, and mounting location before installation. The AX490 uses a plug-in connector with a bolt-on attachment method, so the mounting bracket and sensor position should align with the original setup on the vehicle. Inspect the connector for bent terminals, moisture, or corrosion before connecting the new sensor.

For best results, confirm fitment against the vehicle’s year and model before ordering. This part is listed for 2011-2017 Nissan Quest applications.
