Walker 250-24137 Oxygen Sensor

Walker Products OE Oxygen Sensor for Lexus and Toyota

Walker Products OE 250-24137 is a specific-fit heated oxygen sensor engineered for direct replacement in select Lexus and Toyota applications. It is built to deliver the diagnostic feedback the ECU expects, helping maintain proper fuel control and emissions performance.

Key Features

• Heated oxygen sensor with 4-wire design
• Specific-fit application for correct vehicle placement
• Threaded mounting with 18.0 mm thread diameter
• Radiused polygon male connector for OE-style connection
• Wiring harness length: 29.06 in.; overall length: 32.6 in.
• Walker Products OE line for application-specific engine management replacement parts

Application Details

Walker Products OE 250-24137 is designed for upstream and downstream positions across select 1998-2005 Lexus GS300 and 2001-2004 Toyota Highlander and RAV4 applications. For fitment-specific searches, this oxygen sensor is listed for 1998-2005 Lexus GS300 upstream, 2001-2003 Toyota Highlander downstream, 2004 Toyota Highlander downstream bank 1 sensor 2, and 2001-2003 Toyota RAV4 downstream front or downstream rear positions. This part number, 250-24137, is built for the exact sensor location and ECU feedback requirements of the listed vehicles.

What This Oxygen Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Rough engine operation caused by incorrect air-fuel feedback
• Increased fuel consumption from inaccurate exhaust readings
• Higher exhaust emissions from a failing heated oxygen sensor
• Fault codes stored in the ECU for the affected sensor circuit

Installation Notes

Confirm the sensor position before installation, since this part is listed for upstream, downstream, downstream front, and downstream rear locations depending on vehicle application. Inspect the sensor wiring harness and connector for damage before replacement, and verify the threaded mounting point is clean and undamaged. For Toyota Highlander and Toyota RAV4 applications, match the exact year, model, and sensor position shown in the fitment data. The part number 250-24137 should be matched to the vehicle’s original sensor location for proper ECU feedback.
