Detailed Description

The Walker Products Aftermarket line focuses on engine management and oxygen/air-fuel sensors engineered as direct OE-style replacements for a wide range of vehicles. Part number 350-34362 is built for specific placement and feedback requirements, making it a practical choice for downstream and upstream oxygen sensor service on select 2001-2005 Honda Civic models, 2002 Honda Accord, 2001-2002 Acura EL, and 2002-2004 Acura RSX applications. This part number 350-34362 is intended for vehicles that require a heated, threaded oxygen sensor with the listed connector and harness specifications.

What It Helps Address

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

Installation Notes and Tips

Verify the vehicle position before ordering, since this sensor is listed for both upstream and downstream locations depending on application. Confirm connector shape, wire count, thread diameter, and harness length against the original sensor before installation. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion, since physical damage can shorten service life and affect ECU feedback. For fitment searches, this part is commonly referenced for Fits 2001-2003 Honda Civic, upstream; Fits 2002-2005 Honda Civic, downstream; Fits 2002 Honda Accord, downstream; Fits 2002-2004 Acura RSX, downstream; and Fits 2001-2002 Acura EL, downstream.
