Oxygen Sensor Upstream 234-9092 for Toyota Highlander and Subaru Tribeca

This upstream oxygen sensor 234-9092 from IWOKPHD is designed to fit Toyota Highlander (2009–2013, 2.7L L4) and Subaru models including Legacy (2010–2014), Outback (2010–2014), and Tribeca (2010–2014) with a 3.6L H6 engine. As a heated upstream O2 sensor that uses magnetic induction, it delivers fast, reliable readings before the catalytic converter. Replacing a worn or faulty upstream sensor helps stabilize the air‑fuel ratio, reduce emissions, and improve engine response, idle stability, and overall drivability. This part aligns with multiple OEM numbers, offering a robust, cost‑effective replacement that keeps your vehicle running clean and efficient.

Benefits & Tips

Benefits: The heated design ensures quicker sensor warm‑up, producing stable oxygen readings even in cold starts. Magnetic induction sensing provides dependable signal transmission to the engine control unit, supporting precise fuel trimming for better acceleration and fuel efficiency.

Practical uses: Ideal as a direct replacement to restore smooth idle and responsive throttle on affected Highlanders and Subarus. It helps prevent check engine lights caused by upstream O2 sensor deterioration and supports consistent emissions performance during inspections.
