Keep your engine's air-fuel ratio dialed in with the DENSO Oxygen Sensor 234-2050, a universal 2-wire, unheated sensor that serves as a replacement for a range of Toyota and Geo applications — including the 1989-1995 GEO PRIZM [L4-1.6L], the 1990-1995 TOYOTA COROLLA [L4-1.6L], the 1996 TOYOTA CAMRY [L4-2.2L], and the 1991-1995 TOYOTA PREVIA [L4-2.4L] (see the Buyer's Guide tab for the full list of 14 applications). It can be installed in the upstream or downstream position.

The oxygen sensor measures the oxygen content in the exhaust stream and signals the engine computer, which uses that reading to fine-tune the air-fuel ratio. If a worn or contaminated sensor is the cause, replacing it with this unit restores an accurate exhaust reading.

  • Laser-welded stainless housing: resists corrosion, while a PTFE filter blocks contaminants under harsh engine conditions.
  • Dual-layer protection: shields the ceramic element for fast, reliable response.
  • Aluminum oxide trap layer: DENSO's exclusive layer helps protect the ceramic element from silicone and lead poisoning, designed to support engine performance and fuel efficiency.
  • OE-standard build: manufactured and tested to strict OE standards and precision-built for exact replacement.
