Walker 350-34236 Oxygen Sensor - Downstream

Walker 350-34236 Downstream Oxygen Sensor

Walker Products 350-34236 is a heated downstream oxygen sensor built for specific-fit replacement on select Volvo applications. It is engineered to provide the ECU with the feedback needed for emissions monitoring and fuel control diagnostics on 1996-1998 Volvo 960, 1997-1998 Volvo S90, and 1997-1998 Volvo V90 models.

Key Features

• Specific-fit heated oxygen sensor for downstream installation
• 18.0 mm thread diameter with threaded mounting type
• 4-wire design with 20-gauge wiring
• Radiused polygon male connector for vehicle-specific connection
• Wiring harness length: 82.2 in.; overall length: 85.75 in.
• OE-style replacement from Walker Products Aftermarket

Product Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors developed as OE replacement parts for a wide range of vehicles. Part number 350-34236 is built for the downstream position and matched to the application-specific fitment and connector layout required by the vehicle’s diagnostic system. For Volvo S90, Volvo V90, and Volvo 960 models, this sensor supports the ECU’s ability to monitor exhaust performance and identify sensor-related faults.

This part number, 350-34236, is intended for direct replacement use on the listed Volvo applications. If the original sensor has failed, the vehicle may store fault codes and show drivability or emissions-related symptoms. Walker Products has supplied engine management components since 1946 and manufactures sensors under ISO 9001/TS 16949 quality systems.

What It Helps Address

• Check engine light related to downstream oxygen sensor faults
• Poor fuel economy caused by inaccurate exhaust feedback
• Elevated exhaust emissions from a failing sensor
• Stored ECU fault codes tied to the oxygen sensor circuit
• Rough engine operation linked to emissions system feedback issues

Installation Notes

Fits 1996-1997 Volvo 960, downstream. Fits 1997-1998 Volvo S90, downstream. Fits 1997-1998 Volvo V90, downstream. Confirm the connector shape, thread diameter, and harness routing before installation. Inspect the sensor wiring harness and connector for damage, since physical wear can shorten service life and affect diagnostic performance.

Quality Assurance

Walker Products Aftermarket manufactures this oxygen sensor as an OE-style replacement with application-specific fitment and diagnostic feedback requirements in mind. The brand’s engine management components are produced under ISO 9001/TS 16949 certified quality systems.
