Walker 350-34386 Oxygen Sensor

Walker 350-34386 Oxygen Sensor for Honda and Acura

Walker Products 350-34386 is a heated oxygen sensor built as a specific-fit replacement for select Honda, Acura, and Saturn applications. It is engineered to provide the ECU with the feedback needed for accurate fuel control and emissions monitoring, especially in downstream rear and upstream positions.

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors for OE-style replacement needs. The 350-34386 is part of that product line, with application-specific fitment and connector design for the listed vehicles.

Key Features

• Heated oxygen sensor for emissions and fuel-trim feedback
• Specific-fit design for the listed Honda, Acura, and Saturn applications
• 4-wire configuration with a radiused polygon male connector
• Threaded mounting with 18.0 mm thread diameter
• Wiring harness length: 23.15; overall length: 26.69
• Built for ECU diagnostic feedback on the correct sensor position

Detailed Description

The Walker 350-34386 oxygen sensor is designed for vehicles that rely on precise exhaust-gas feedback to manage air-fuel ratio and emissions performance. This part number is listed for multiple Honda Accord, Honda Odyssey, Honda Pilot, Honda Ridgeline, Honda S2000, Acura MDX, Acura RL, Acura TL, Acura NSX, and Saturn Vue applications, including downstream rear, downstream front, upstream rear, upstream front, and upstream positions where specified. For fitment-sensitive repairs, the sensor must be installed in the exact position called out for the vehicle.

This part cross-references no additional part numbers in the provided data. Use Walker Products 350-34386 when replacing a failed oxygen sensor on supported vehicles such as the 2003-2007 Honda Accord, 2005-2010 Honda Odyssey, or 2004-2006 Acura TL, and verify the connector, thread size, and sensor location before installation.

What It Helps Fix

• Check engine light or MIL illumination related to oxygen sensor faults
• Poor engine performance caused by incorrect exhaust feedback
• Increased fuel consumption from inaccurate air-fuel control
• Higher exhaust emissions from a degraded sensor signal
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes and Tips

Confirm the exact year, make, model, and sensor position before ordering. This application uses a threaded, heated sensor with a male connector, so the harness routing and connector shape should match the original unit. Inspect the sensor wiring harness and connector for physical damage before installation, since damaged wiring can shorten service life and trigger additional fault codes. For vehicles listed with rear downstream or upstream positions, install the sensor in the correct bank and location specified for that application.

Quality Assurance

Walker Products states that its engine management and oxygen/air-fuel sensors are developed as OE replacement parts for worldwide vehicle applications. The company is ISO 9001/TS 16949 certified and has supplied engine management and fuel system components since 1946.
