Detailed Product Overview
Walker 350-84005 is an oxygen sensor set designed to meet or exceed original equipment specifications for the listed vehicles. These sensors monitor exhaust oxygen content so the engine control system can adjust fueling, helping maintain proper combustion efficiency and emissions control. The heated narrow-band design helps the sensor reach operating temperature quickly for consistent signal response during normal driving conditions.
This part number is a direct-fit solution for 2003-2005 Cadillac Escalade, Chevrolet Avalanche 1500, Chevrolet Silverado 1500, Chevrolet Suburban 1500, Chevrolet Tahoe, GMC Sierra 1500, GMC Yukon, and GMC Yukon XL 1500 models. If you are searching for a Walker oxygen sensor set for 2003-2005 Chevrolet Silverado 1500 or a Walker O2 sensor kit for 2003-2005 GMC Sierra 1500, 350-84005 matches the listed OE replacement applications.
This part cross-references Bosch 15717 and Denso 234-4668 for the same application.
What It Helps Address
- Rich or lean fuel mixture readings caused by aging oxygen sensors
- Check engine light concerns related to O2 sensor performance
- Reduced fuel economy from inaccurate exhaust feedback
- Emissions test failures tied to sensor degradation
- Rough engine operation caused by poor air-fuel ratio control
Installation Notes and Tips
Verify the connector style, thread size, and sensor location before installation. Use the vehicle service information for the correct sensor positions on your specific Cadillac Escalade, Chevrolet Silverado 1500, or GMC Yukon application. Because this is a threaded sensor with an M18 - 1.5 thread size, proper removal and installation tools help reduce the risk of exhaust bung damage.
Inspect the exhaust system and wiring harness for heat damage, corrosion, or contamination before replacing the sensors. Clear diagnostic trouble codes after installation and confirm that the engine control system completes its readiness monitors.
Quality Assurance
Walker Products builds OE Replacement sensors to align with original equipment specifications and tests them for dependable operation across domestic and import vehicle coverage. The 350-84005 part number is backed by Walker’s emissions-control focus and application-specific engineering for routine maintenance service.
