Detailed Description

Part number 250-24145 is an OE-style oxygen sensor from Walker Products OE, a product line focused on replacement engine management sensors for factory-style fitment and signal output. This heated sensor is designed to provide the ECU with the exhaust data needed for fuel control and emissions monitoring. For buyers searching for a Walker oxygen sensor for a specific vehicle application, 250-24145 is built around the listed harness length, connector style, and threaded installation format.

This part cross-references common oxygen sensor replacement needs for the same application, including Bosch 15717 and Denso 234-9005.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Poor fuel economy caused by inaccurate exhaust feedback
• Rough running or inconsistent air-fuel control
• Higher exhaust emissions from a failing sensor
• Fault codes stored in the ECU for sensor circuit or response issues

Installation Notes and Tips

Confirm the sensor position, connector shape, and harness length before installation. Inspect the wiring harness and connector for heat damage, corrosion, or physical wear, since damaged wiring can shorten sensor life and affect readings. Use the threaded mounting point and thread diameter specified for the application, and verify the vehicle’s original connector style matches the sensor before replacement.

Compatible With select vehicle applications that use this exact Walker Products OE oxygen sensor configuration, including fitment-specific make/model listings such as Honda Civic and Toyota Corolla where the catalog application matches the vehicle.
