Key Features
- Heated oxygen sensor for faster operating response
- Specific fit for the correct application and mounting position
- Upstream location for Bank 1 Sensor 1 service needs
- 4-wire design with a female radiused polygon connector
- 18.0 mm thread diameter and threaded mounting type
- Wiring harness length: 19.21 in.; overall length: 22.76 in.
- Wire gauge: 20
Product Details
Walker Products Aftermarket 350-64023 is part of the Walker Products Engine Management and Oxygen/Air-Fuel sensor line, developed for OE replacement use across a wide range of vehicles. For 2004-2005 Honda Civic upstream oxygen sensor service, this part is specified for Bank 1 Sensor 1 and front oxygen sensor applications listed in the fitment data. The sensor is designed to deliver the diagnostic feedback the ECU expects, helping maintain proper fuel control and emissions monitoring.
This part cross-references standard oxygen sensor replacement applications for the same vehicle fitment.
What It Helps Address
- Check engine light related to upstream oxygen sensor faults
- Poor engine performance caused by incorrect air-fuel feedback
- Increased fuel consumption from inaccurate exhaust readings
- Higher exhaust emissions from a failing sensor
- Stored ECU fault codes tied to the oxygen sensor circuit
Installation Notes and Tips
Verify the connector shape, wire count, thread diameter, and upstream position before installation. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion, since damaged wiring can shorten sensor life and affect readings. Confirm the vehicle is a 2004-2005 Honda Civic with an upstream oxygen sensor requirement before ordering.
Quality Assurance
Walker Products has manufactured engine management components since 1946 and operates under Automotive ISO9001/TS 16949 quality systems. The 350-64023 is built as a specific application replacement for the listed Honda Civic fitment.
