Product Details

Walker Products part number 350-64096 is designed as an OE-style replacement oxygen sensor for the upstream position on 2006-2008 Honda Civic models. The heated sensor design helps the engine management system monitor exhaust oxygen content and maintain accurate air-fuel feedback to the ECU. This part number is built for the specified application and fitment position, making it a direct choice for Honda Civic upstream oxygen sensor replacement service.

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors for a wide range of vehicles. The 350-64096 reflects that product line approach with application-specific fitment, a threaded mount, and a connector layout intended to match the original sensor location. Part number 350-64096 is also referenced as a front oxygen sensor option for the same Honda Civic year range.

Common Issues This Sensor May Address

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

Installation Notes

Verify the upstream location before installation and compare the connector shape, wire count, and thread size to the original sensor. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion, since physical damage can shorten service life and affect signal quality. Confirm the vehicle application against the Honda Civic year range and position listed for part number 350-64096.

Quality Assurance

Walker Products states that its engine management sensors are developed as original equipment replacement parts and manufactured under ISO 9001/TS 16949 quality systems. Part number 350-64096 is built to deliver the diagnostic feedback expected by the ECU for the specified application.
