Walker Products Engine Management Line

Walker Products Aftermarket engine management sensors are developed as OE-style replacements for a wide range of vehicles. The brand focuses on application-specific fitment, correct connector and harness design, and sensor output that matches the vehicle’s diagnostic requirements. Part number 350-35065 follows that approach for select Honda and Acura upstream oxygen sensor locations.

Detailed Description

Walker 350-35065 is an emission control oxygen sensor designed for upstream front and upstream rear positions on select Acura and Honda models. It is a heated, threaded sensor with a 20-gauge harness and a male radiused polygon connector, helping ensure proper installation in the intended exhaust location. This part number is listed for applications such as 2015-2020 Acura MDX, 2015-2020 Acura RLX, 2015-2020 Acura TLX, 2009-2020 Honda Pilot, and 2011-2017 Honda Odyssey.

When an oxygen sensor begins to fail, the vehicle can run poorly, consume more fuel, increase exhaust emissions, or trigger the malfunction indicator light. Walker Products 350-35065 is built for the specified ECU feedback and fitment position, making it a direct replacement choice for the affected sensor location. This part cross-references Walker Products Aftermarket 350-35065 for the same application.

What This Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Rough running or incorrect air-fuel feedback
• Reduced fuel economy from inaccurate exhaust readings
• Higher exhaust emissions from a failing upstream sensor
• Diagnostic trouble codes tied to the affected sensor circuit
