Product Details

The Walker Products OE line focuses on direct replacement engine management components built for the correct vehicle, position, and diagnostic response. Part number 250-24324 is a specific-fit heated oxygen sensor used in upstream locations on select Cadillac CTS, Cadillac STS, Cadillac SRX, Chevrolet Equinox, Pontiac Torrent, and Suzuki XL-7 applications. It is designed to provide the signal the ECU uses to manage air-fuel ratio, monitor exhaust performance, and support emissions control.

Walker Products has supplied engine management and oxygen sensor components since 1946, and this OE product line is built around application-specific fitment rather than universal coverage. If a sensor fault is present, the vehicle may store ECU codes and show drivability or emissions-related symptoms. This part cross-references no listed interchange numbers in the provided data.

Common Issues This Sensor May Address

• Check engine light related to oxygen sensor performance
• Poor fuel economy caused by incorrect air-fuel feedback
• Rough engine operation from inaccurate exhaust readings
• Elevated exhaust emissions from a failing upstream sensor
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes and Fitment

Compatible With 2007-2009 Cadillac SRX, upstream front and upstream rear; 2008-2011 Cadillac STS, upstream left and upstream right; 2008-2011 Cadillac CTS, upstream left and upstream right; 2008-2009 Chevrolet Equinox, upstream front and upstream rear; 2008-2009 Pontiac Torrent, upstream front and upstream rear; and 2007-2009 Suzuki XL-7, upstream front and upstream rear. For 2008 Cadillac CTS, this sensor also applies to upstream left and upstream right direct-injection configurations.

Before installation, inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion. Confirm the mounting position and connector style match the original part, and verify the exhaust threads are clean before threading the sensor into place.

Quality Assurance

Walker Products OE sensors are manufactured as application-specific replacement parts for the listed vehicles and positions. The brand operates under Automotive ISO9001/TS 16949 certification and builds components to support the diagnostic feedback expected by the ECU.
