Walker 350-34247 Oxygen Sensor

Walker 350-34247 Oxygen Sensor Overview

Walker Products 350-34247 is a specific-fit heated oxygen sensor engineered as an OE-style replacement for select Suzuki and Chevrolet applications. It is built for upstream placement and provides the ECU with the feedback needed for proper fuel control and emissions monitoring.

For vehicles such as the Chevrolet Tracker and Suzuki Vitara, a worn upstream oxygen sensor can trigger fault codes, rough running, higher fuel use, or increased exhaust emissions. This Walker Products Aftermarket sensor is matched to the application, connector style, and mounting position for direct replacement service.

Product Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors built for OE replacement use. The 350-34247 is manufactured for the specified vehicle, sensor position, and ECU feedback requirements, making it a practical choice when replacing an upstream oxygen sensor on a Chevrolet Tracker or Suzuki Vitara. This part number also applies to Suzuki XL-7 and Grand Vitara fitments listed below.

This part cross-references common OE-style replacement applications for the same vehicle positions.

What It Helps Fix

• Check engine light related to upstream oxygen sensor faults
• Rough idle or poor engine performance caused by incorrect air-fuel feedback
• Increased fuel consumption from inaccurate exhaust readings
• Elevated exhaust emissions from a failing sensor
• Stored ECU fault codes tied to the affected sensor circuit

Installation And Quality

Before installation, inspect the sensor wiring harness and connector for heat damage, corrosion, or abrasion. Confirm the upstream mounting location and thread size match the vehicle application, and verify the connector orientation before tightening the threaded sensor into place. If the original sensor failed due to wiring or connector damage, repair those issues before installing the replacement.

Walker Products has supplied engine management and fuel system components since 1946 and manufactures this sensor as an OE replacement for the listed applications. The company is ISO 9001/TS 16949 certified, supporting consistent production and application-specific fitment.
