Walker 350-35067 Oxygen Sensor

Walker 350-35067 Oxygen Sensor Overview

Walker Products 350-35067 is a heated oxygen sensor built as an OE-style replacement for specific Ford, Volkswagen, Audi, Porsche, and Lincoln applications. It is engineered for the correct fitment position and ECU feedback, helping maintain accurate air-fuel monitoring on vehicles that rely on precise upstream sensor input.

For drivers searching for an upstream oxygen sensor for Ford F-150, Ford Bronco Sport, or Volkswagen Passat applications, this part number provides a direct replacement option with application-specific fitment.

Key Features

• Heated oxygen sensor for faster operating response
• Specific fit design for the listed vehicle applications
• 5-wire configuration with a 20-gauge harness
• 27.09 in. wiring harness length and 30.63 in. overall length
• Threaded mounting with 18.0 mm thread diameter
• Male connector with radiused polygon connector shape
• OE replacement design for upstream and selected downstream positions

Detailed Description

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors engineered to replace original equipment parts across a wide range of vehicles. Part number 350-35067 is built for specific applications and positions, including upstream, upstream right, upstream left, upstream front, upstream rear, and selected downstream locations where listed in the fitment data.

This sensor is used on many 2004-2024 applications, including Ford Bronco Sport, Ford Escape, Ford F-150, Ford Expedition, Lincoln Navigator, Volkswagen Tiguan, Volkswagen Passat, Audi A4, Audi Q5, Audi Q7, and Porsche Panamera. It is a direct-fit oxygen sensor solution for vehicles that require accurate exhaust-gas feedback to the ECU.

This part cross-references no additional part numbers provided in the source data.

What This Oxygen Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Poor fuel economy caused by inaccurate air-fuel feedback
• Rough engine operation from a failing upstream sensor
• Elevated exhaust emissions from incorrect sensor readings
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes and Tips

• Confirm the exact position before ordering: upstream, upstream right, upstream left, upstream front, upstream rear, or downstream as listed.
• Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation.
• Verify thread size and connector style against the original sensor to ensure proper replacement.
• Use the vehicle’s fault codes and service information to confirm Bank 1 Sensor 1 or other position-specific requirements.
• Clear stored ECU codes after installation and verify closed-loop operation.
