Detailed Description

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors engineered for OE replacement use. Part number 350-64069 is built for specific fitment and the correct sensor position, helping maintain the diagnostic feedback the ECU relies on for air-fuel control. This sensor is listed for 2003-2007 Honda Accord upstream applications, including Bank 1 Sensor 1 service and front oxygen sensor replacement on the covered vehicles. If you are searching for a 2003-2007 Honda Accord upstream oxygen sensor or a Walker 350-64069 replacement oxygen sensor, this part matches that service need.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

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

Installation Notes and Tips

Confirm the vehicle is a 2003-2007 Honda Accord with an upstream sensor location before ordering. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation, since physical damage can shorten sensor life. Verify the threaded mounting point and connector style match the original unit, and clear diagnostic trouble codes after repair if required by the vehicle.

Quality Assurance
