Walker 350-34363 Oxygen Sensor

Walker 350-34363 Oxygen Sensor Overview

Walker Products 350-34363 is a heated oxygen sensor built as a specific-fit OE replacement for select Honda, Acura, and Saturn applications. It is engineered to deliver the ECU feedback needed for accurate fuel control and emissions monitoring, with fitment matched to the vehicle position.

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors for direct replacement use. The 350-34363 part number is application-specific, with a threaded mounting design, 4-wire configuration, 18.0 mm thread diameter, and a radiused polygon male connector.

Key Features

• Heated oxygen sensor for closed-loop engine management
• Specific fit for the listed vehicle applications and sensor positions
• 4-wire design with 20-gauge wiring
• 17.24 in. wiring harness length and 20.79 in. overall length
• Threaded mounting type with 18.0 mm thread diameter
• Radiused polygon male connector for vehicle-specific connection

Detailed Description

Walker Products 350-34363 is designed for downstream front, upstream front, upstream rear, and upstream positions depending on the application. It is listed for vehicles including the Honda Odyssey, Honda Pilot, Honda Ridgeline, Honda Accord, Honda Civic, Acura MDX, Acura RL, Acura TL, and Saturn Vue. For example, it fits 2005-2010 Honda Odyssey, downstream front; 2003-2007 Honda Accord, downstream front; and 2003-2006 Acura MDX, downstream front.

As an OE-style replacement oxygen sensor, this part is intended to restore proper exhaust feedback to the ECU when the original sensor has aged or failed. The sensor design supports the diagnostic system by providing the signal needed for fuel trim and emissions control on the listed applications. This part number is also referenced as Walker Products Aftermarket 350-34363.

What It Is Used For

• Check engine light related to oxygen sensor performance
• Rough running or poor fuel control caused by a failing sensor
• Increased fuel consumption from inaccurate exhaust feedback
• Higher exhaust emissions from degraded sensor response
• Fault codes stored in the ECU for the affected sensor circuit

Installation Notes and Tips

Confirm the exact year, make, model, and sensor position before ordering. This part is specific fit, so the downstream front, upstream front, upstream rear, or upstream location must match the vehicle listing. Inspect the sensor wiring harness and connector for damage before installation, since physical damage can shorten sensor life and affect operation.

For fitment examples, this part fits 2002-2004 Honda Odyssey, upstream; 2004 Honda Pilot, upstream front and upstream rear; and 2001-2002 Acura MDX, upstream. If the vehicle has stored diagnostic trouble codes, verify the affected circuit and sensor location before replacement.

Quality Assurance

Walker Products has produced engine management and fuel system components since 1946 and operates as an Automotive ISO9001/TS 16949 certified company. The 350-34363 oxygen sensor is built to meet the application-specific requirements of the listed vehicles and positions.
