Detailed Description

Walker Products 350-34457 is part of the Walker Products Aftermarket engine management line, which is focused on replacement sensors for vehicle-specific applications. This oxygen sensor is built for the downstream right location on the Volvo XC90 and is intended to deliver the signal feedback the ECU expects from that position. If you are replacing a failed downstream oxygen sensor on a 2007-2014 Volvo XC90, this part number 350-34457 matches the listed fitment and mounting style.

Walker Products has long supplied oxygen and air-fuel sensors for OE-style replacement use, with manufacturing processes aligned to automotive quality standards. The sensor’s heated design, 4-wire layout, and threaded installation help support accurate exhaust monitoring in the specified application. This part cross-references Monroe Shocks & Struts (e.g., 172286) for the same application.

What This Sensor Helps Address

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

Installation Notes and Tips

Before installation, inspect the sensor wiring harness and connector for heat damage, corrosion, or physical wear. Confirm the downstream right location on the Volvo XC90 and verify the threaded mounting point is clean and undamaged before threading in the replacement sensor. Because this is a specific-fit part, matching the connector shape, wire count, and sensor position is important for proper installation.

Quality Assurance

Walker Products is an automotive ISO 9001/TS 16949 certified company, and its sensor line is built around application-specific replacement requirements for engine management systems. Part number 350-34457 is manufactured for the listed vehicle position and diagnostic feedback needs of the ECU.
