Walker 350-34483 Oxygen Sensor

Walker 350-34483 Oxygen Sensor Overview

Walker Products 350-34483 is a heated oxygen sensor built as a direct-fit OE-style replacement for specific GM applications. It is engineered for the correct mounting position and ECU feedback, helping maintain accurate air-fuel monitoring on vehicles such as the Chevrolet Silverado 1500, GMC Sierra 1500, and Chevrolet Spark.

Walker Products Aftermarket focuses on application-specific engine management sensors, and this oxygen sensor follows that approach with the proper connector, wire length, and threaded mounting design for the listed vehicles.

Key Features

• Heated oxygen sensor for precise exhaust feedback
• Specific-fit design for the listed year, make, model, and position
• 4-wire configuration with 20-gauge wiring
• Radiused polygon male connector for vehicle-specific connection
• 18.0 mm thread diameter with threaded mounting type
• 14.49 in. wiring harness length and 18.03 in. overall length
• Walker Products 350-34483 for direct replacement service

Detailed Description

This Walker oxygen sensor is designed to replace the original sensor on confirmed applications from 2006 through 2017, including downstream and upstream positions across Chevrolet, GMC, Buick, Cadillac, Hummer, Pontiac, Saab, and Isuzu models. It is a practical choice for drivers addressing oxygen sensor fault codes, poor fuel control, elevated emissions, or a malfunction indicator light tied to the exhaust monitoring system. The part number 350-34483 is built for specific fitment, so the sensor location and connector style match the vehicle application rather than using a universal layout.

Compatible vehicle examples include Fits 2007-2013 Chevrolet Silverado 1500, upstream right or upstream left; Fits 2006-2013 GMC Sierra 1500, upstream right or upstream left; and Fits 2013-2016 Chevrolet Spark, downstream. This part cross-references no listed aftermarket part numbers in the provided data.

What It Helps Address

• Oxygen sensor fault codes stored in the ECU
• Rough engine operation caused by incorrect exhaust feedback
• Increased fuel consumption from inaccurate air-fuel readings
• Elevated exhaust emissions from a failing sensor
• Malfunction indicator light related to the sensor circuit

Installation Notes and Tips

Confirm the exact position before ordering, since this sensor is listed for upstream and downstream locations depending on the vehicle. Check the sensor, wiring harness, and connector for physical damage before installation. Verify thread diameter, connector shape, and harness length against the original part to ensure proper routing and fit. For vehicles such as the Chevrolet Silverado 1500 and GMC Sierra 1500, match the bank and side noted in the fitment data.

Quality Assurance

Walker Products manufactures engine management and oxygen sensors as OE-replacement parts for specific applications and produces them under Automotive ISO9001/TS 16949 certified processes. Part number 350-34483 is built to provide the diagnostic feedback required by the ECU on the listed vehicles.
