Quick facts

• Part: Walker Products 250-24137 oxygen sensor
• Fits: 2001-2003 Toyota RAV4 4-cylinder 2.0L and other vehicles

A failed oxygen sensor might make the engine run poorly, raise fuel consumption or exhaust emissions, or light the malfunction indicator light. Before you replace the sensor, look its wiring harness and connector over for physical damage with the engine off and cool, since damage there could be behind the fault code instead.

Fits

The sensor is a direct-fit replacement for the 2001-2004 Toyota Highlander 4-cylinder 2.4L. It is also an oxygen sensor for the 1998-2005 Lexus GS300 6-cylinder 3.0L. This listing is one sensor, and the fitment calls for one per vehicle.
