Walker 350-34113 Oxygen Sensor

Walker 350-34113 Oxygen Sensor Overview

Walker Products 350-34113 is a heated oxygen sensor built as a specific-fit OE-style replacement for select Porsche and Volvo applications. It is engineered to provide the ECU with the feedback needed for proper fuel control and emissions monitoring.

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors for application-specific fitment, and this sensor follows that approach with the correct connector, thread size, and harness length for the listed vehicles.

Key Features

• Heated oxygen sensor for faster operating response
• Specific-fit design for the listed Porsche 911 and Volvo C70, S70, and V70 applications
• 4-wire configuration with 20-gauge wiring
• 32.6 in. wiring harness length and 36.14 in. overall length
• 18.0 mm threaded mounting design
• Radiused polygon connector shape with male connector end

Detailed Product Description

The Walker 350-34113 oxygen sensor is designed for direct replacement in select 1995-1998 Porsche 911 and 1998 Volvo models, including downstream and upstream positions where listed. As an emissions control sensor, it helps the engine control module monitor exhaust oxygen content so the ECU can adjust air-fuel strategy and maintain proper system feedback.

This part number is built for the specified application and fitment position, which is important on vehicles such as the Porsche 911 and Volvo C70, S70, and V70 where sensor location and connector style must match the original setup. Walker Products 350-34113 is intended for the exact chassis and factory-code listings shown below.

Vehicle Fitment

• Fits 1995-1998 Porsche 911, upstream right.
• Fits 1995-1998 Porsche 911, upstream left.
• Fits 1996-1997 Porsche 911, downstream right.
• Fits 1996-1997 Porsche 911, downstream left.
• Fits 1998 Volvo C70, downstream.
• Fits 1998 Volvo S70, downstream, from chassis #409466 with factory code 1.
• Fits 1998 Volvo S70, downstream, chassis #408556 with factory code 2.
• Fits 1998 Volvo V70, downstream, up to chassis #342000.

Common Issues This Sensor May Address

• Check engine light or malfunction indicator light related to oxygen sensor performance
• Poor engine operation caused by incorrect exhaust feedback
• Increased fuel consumption from inaccurate air-fuel control
• Higher exhaust emissions from a failing sensor
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes and Tips

Confirm the sensor position before ordering, since this part is listed for specific upstream and downstream locations. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation, and verify the thread diameter and connector style match the original unit.

For Volvo applications, match the chassis number and factory code exactly. For Porsche 911 applications, verify whether the vehicle requires the upstream right, upstream left, downstream right, or downstream left position.

Quality Assurance

Walker Products manufactures engine management sensors as OE-replacement parts for specific applications and supports them with ISO 9001/TS 16949 certified production practices. Part number 350-34113 reflects that application-specific approach for emissions control service on select Porsche and Volvo vehicles.
