Walker 350-35061 Oxygen Sensor - Upstream Front or Upstream Rear

Walker 350-35061 Oxygen Sensor for Honda and Acura

Walker Products 350-35061 is a heated, specific-fit oxygen sensor engineered as an OE-style replacement for select Honda Accord and Acura RLX applications. It is built for the correct mounting position, connector style, and ECU feedback required by the vehicle’s emissions system.

Key Features

• Heated oxygen sensor for accurate exhaust feedback
• Specific fit for the listed Honda Accord and Acura RLX applications
• 5-wire design with 20-gauge wiring
• Radiused polygon male connector for proper harness connection
• Threaded mounting with 18.0 mm thread diameter
• Wiring harness length: 7.4; overall length: 10.94

Product Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors developed for OE replacement use. Part number 350-35061 is made for the exact application and position listed in the fitment data, helping the ECU receive the diagnostic signal it expects from the upstream rear or upstream front location. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. It is a direct-fit oxygen sensor choice for 2013-2017 Honda Accord, 2016-2020 Acura RLX, and 2008-2009 Honda Accord California emissions applications.

What It Helps Address

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

Installation Notes and Tips

Verify the vehicle’s exact year, make, model, emissions package, and sensor position before ordering. For 2013-2017 Honda Accord and 2016-2020 Acura RLX applications, confirm whether the vehicle uses the upstream front or upstream rear location shown in the fitment table. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation. If the original sensor failed from wiring or connector damage, repair those issues so the replacement sensor can operate correctly.

Quality Assurance

Walker Products states that its engine management sensors are developed as OE replacement parts and manufactured under Automotive ISO9001/TS 16949 certification standards. Since 1946, Walker Products has supplied engine management and fuel system components for vehicle applications worldwide.
