Downstream Lambda O2 Sensor for Mazda MPV 1996-2006

This downstream Lambda O2 sensor is a heated, piezoelectric oxygen sensor designed specifically for Mazda MPV models from 1996 to 2006. As the downstream sensor (post-catalytic converter), it monitors exhaust gas composition after the catalyst, helping your engine management system optimize combustion, reduce emissions, and maintain fuel efficiency. A precise replacement ensures your ECU reads accurate feedback, supporting stable fuel trims and preventing unnecessary check engine lights.

Crafted as a direct replacement with careful alignment to factory specifications, this unit relies on a heating element for rapid warm-up and reliable readings across temperature ranges. Its robust electrical connection is built to withstand the automotive environment, delivering consistent performance for years of service.
