Walker 350-34534 Oxygen Sensor

Walker 350-34534 Oxygen Sensor Overview

Walker Products 350-34534 is a heated oxygen sensor built as a specific-fit OE replacement for select Honda and Acura applications. It is engineered to deliver the ECU feedback needed for accurate fuel control and emissions monitoring, including downstream and upstream positions where listed.

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors for precise application fitment. The 350-34534 follows that approach with a threaded, female-connector design and vehicle-specific configuration for Honda Accord, Honda Civic, Honda Odyssey, Acura CL, Acura EL, Acura NSX, Acura TL, and Honda Fit coverage in the listed positions.

Key Features

• Part number: 350-34534
• Heated oxygen sensor for faster operating response
• Specific fit design for direct application matching
• 4-wire configuration with 20-gauge wiring

Detailed Description

Walker Products 350-34534 is an OE-style oxygen sensor intended for vehicles that rely on accurate exhaust-gas feedback to manage air-fuel ratio and emissions performance. As a heated sensor, it helps the system reach operating temperature efficiently, which is important for stable ECU input during cold starts and normal driving. This part number is engineered for specific fitment, so the connector, harness length, thread size, and mounting style align with the listed vehicle applications.

Fitment includes 2006 Honda Fit, downstream; 2004-2005 Acura EL, downstream; 2000-2005 Acura NSX, downstream rear; 2001-2005 Honda Civic, downstream; 2002-2004 Honda Odyssey, downstream rear and downstream front; 2001-2003 Acura CL, downstream; 2001-2003 Acura EL, upstream; 2000-2003 Acura TL, downstream; 2002-2003 Honda Odyssey, downstream; 2000-2002 Honda Accord, downstream; 1998-2002 Honda Accord, downstream; 1998-2001 Honda Prelude, upstream; 1999 Acura TL, downstream; and 1998-1999 Honda Accord, downstream for California ESV applications. This part cross-references Bosch 15733 for the same application.

What It Helps Address

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

Installation Notes

Verify the sensor position before installation, especially on applications that use downstream rear, downstream front, or upstream locations. Inspect the wiring harness and connector for heat damage, abrasion, or corrosion before replacing the sensor. Confirm thread diameter, connector style, and harness length against the original part to ensure proper routing and fit on Honda Accord, Honda Civic, and Acura EL applications.

Quality Assurance

Walker Products states that its engine management sensors are developed as OE replacement parts and manufactured under Automotive ISO9001/TS 16949 quality systems. The brand has supplied engine management and fuel system components since 1946, with application-specific cataloging and fitment control for modern diagnostic systems.
