• Overall length: 28.86 in.
• Walker Products Aftermarket part number 350-34332

Product Details

Walker Products Engine Management and Oxygen/Air-Fuel sensors are developed as OE-style replacement parts for a wide range of vehicles. This heated downstream oxygen sensor is built for the specified fitment position and connector style, helping maintain the diagnostic feedback the ECU expects. For Saturn SC1, SC2, SL, SL1, SL2, SW1, and SW2 models, the correct downstream sensor can help restore accurate exhaust monitoring after a failed unit has triggered a fault code or MIL light. Walker Products 350-34332 is designed for direct replacement service where the original sensor uses a threaded, 4-wire, heated configuration.

Walker Products is an ISO 9001 / TS 16949 certified manufacturer with a long history in engine management and fuel system components. The Walker Products Aftermarket line focuses on application-specific parts that match the required position and electrical feedback for the vehicle’s control system.

What It Helps Address

• Check engine light related to downstream oxygen sensor faults
• Poor engine performance caused by incorrect exhaust feedback
• Increased fuel consumption from inaccurate air-fuel correction
• Higher exhaust emissions from a failing sensor
• Damaged sensor wiring or connector issues at the original location

Installation Notes and Tips

Verify the connector shape, wire count, and threaded mounting style before installation. Inspect the sensor harness and connector for heat damage, corrosion, or abrasion, since physical damage can shorten service life. This part fits 1996-1999 Saturn SC1, SC2, SL, SL1, SL2, SW1, and SW2 in the downstream position; confirm the vehicle’s original sensor location and ECU fault code before replacement. This part cross-references Walker Products Aftermarket 350-34332 for the same application.

Quality Assurance

Walker Products manufactures engine management sensors to application-specific standards and supports them through ISO 9001 / TS 16949 certified processes. The 350-34332 oxygen sensor is built for the specified Saturn downstream application and the diagnostic feedback required by the ECU.
