Walker 350-34101 Oxygen Sensor - Center, Downstream or Upstream

Walker Oxygen Sensor for Honda and Acura

Walker Products Part Number 350-34101 is a heated oxygen sensor built as a specific-fit OE replacement for select Honda and Acura applications. It is engineered to provide the ECU with the feedback needed for accurate fuel control and emissions monitoring.

Key Features

• Heated oxygen sensor for faster operating response
• Specific-fit design for the listed vehicle positions
• 4-wire configuration with female connector
• Threaded mounting with 18.0 mm thread diameter
• 10.16 wiring harness length and 13.7 overall length
• Radiused polygon connector shape for application-specific fitment

Detailed Description

Walker Products Aftermarket 350-34101 is part of the Walker Products Engine Management and Oxygen/Air-Fuel sensor line, developed as an OE-style replacement for many vehicles worldwide. This sensor is built for the exact application and mounting position required by the vehicle, helping the ECU receive the diagnostic feedback it expects. It is a practical replacement choice for Honda Civic, Honda CR-V, Honda Element, Honda Insight, and Acura EL applications where the original sensor has failed or is reporting incorrect data.

As an oxygen sensor, this part supports closed-loop fuel management and emissions control. When the original sensor becomes slow, damaged, or contaminated, the vehicle may run poorly, use more fuel, or trigger a malfunction indicator light. Walker Products has supplied engine management components since 1946 and manufactures this sensor as a specific-fit replacement for the listed downstream, center, and upstream positions.

This part cross-references no listed alternate part numbers in the provided data.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Rough running caused by incorrect air-fuel feedback
• Increased fuel consumption from a failing sensor signal
• Elevated exhaust emissions from poor mixture control
• Fault codes stored in the ECU for sensor-related issues

Installation Notes and Tips

Verify the vehicle position before ordering, since this part is listed for upstream, center, and downstream locations depending on application. Confirm the connector style, wire count, and thread size match the original sensor. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation, since physical damage can shorten sensor life. For fitment examples, this part fits 2003-2011 Honda Element, downstream; 2005-2006 Honda CR-V, downstream; 2002-2006 Honda Insight, center; 2003-2005 Honda Civic, center; and 1999-2000 Honda Civic, upstream.
