OE Replacement Oxygen Sensor for GM Applications
Walker Products 350-341064 is a heated oxygen sensor built as an OE replacement for specific GM vehicles. It is application-specific for the correct mounting position and provides the ECU with the feedback needed for fuel control and emissions monitoring.
Use this oxygen sensor when diagnosing a check engine light, poor fuel economy, elevated exhaust emissions, or fault codes related to the sensor circuit. Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors for precise fitment on the intended vehicle position.
Key Features
- Heated oxygen sensor for faster operating temperature and stable signal output
- Specific-fit design for the listed vehicle, bank, and sensor position
- 4-wire configuration with male connector
- 18.00 mm thread diameter for the intended exhaust bung
- 10.35 in. wiring harness length and 13.9 in. overall length
- 20-gauge wiring for the OE-style electrical layout
Detailed Description
Walker Products 350-341064 is engineered for direct replacement use on a wide range of Chevrolet, GMC, Buick, and Cadillac models, including Silverado 1500, Sierra 1500, Tahoe, Yukon, Enclave, XT5, and XT6 applications. It is built for the specified upstream or downstream location so the ECU receives the correct oxygen-content feedback for closed-loop fuel management and emissions control. For shoppers searching for a downstream right oxygen sensor for a Chevrolet Silverado 1500 or a heated upstream rear oxygen sensor for a Buick Enclave, this part number is matched to the listed position and vehicle configuration.
Walker Products Aftermarket has supplied engine management components since 1946 and manufactures sensors for specific applications rather than universal use. Part number 350-341064 is also referenced in OE-style replacement searches for GM trucks and SUVs where accurate sensor location matters, including Chevrolet Silverado, GMC Sierra, and Cadillac Escalade platforms.
This part cross-references Bosch 15733 and Denso 234-4668 for the same application.
What It Helps Address
- Check engine light related to oxygen sensor performance or circuit faults
- Poor fuel economy caused by inaccurate exhaust oxygen feedback
- Elevated emissions from incorrect air-fuel ratio control
- Rough running or drivability issues tied to sensor signal loss
- Stored ECU fault codes for the affected sensor position
Installation Notes and Tips
Confirm the exact year, make, model, and sensor position before ordering. This sensor is specific to the listed upstream or downstream location, so bank and side identification matter on vehicles such as the Chevrolet Silverado 1500, GMC Sierra 2500 HD, and Cadillac XT5. Inspect the wiring harness and connector for heat damage, abrasion, or corrosion before installation, and verify the exhaust bung thread size matches the sensor specification.
After installation, clear any stored diagnostic trouble codes and verify that the ECU completes its readiness checks. If the original sensor failed due to wiring or connector damage, repair the underlying issue before replacing the sensor.
Quality Assurance
Walker Products is an ISO 9001 / TS 16949 certified automotive manufacturer with a long history in engine management components. The 350-341064 oxygen sensor is produced as an OE-style replacement for the specified application and position.
