Walker 350-64052 Oxygen Sensor - Upstream

Walker 350-64052 Oxygen Sensor for Honda

Walker Products 350-64052 is a heated upstream oxygen sensor built as a specific-fit OE replacement for select Honda 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 Honda applications
• 4-wire configuration with female connector
• Threaded mounting type with 18.0 mm thread diameter
• Wiring harness length: 8.39 in.; overall length: 11.93 in.
• Radiused polygon connector shape for application-specific fitment

Product Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors developed as OE-style replacements for a wide range of vehicles. Part number 350-64052 is designed for upstream placement and is listed for Honda HR-V, Honda Accord, and Honda Civic applications where the front oxygen sensor is required. This sensor supports the diagnostic feedback the ECU uses to manage air-fuel ratio, emissions performance, and fault detection. If the original sensor is aging or damaged, the vehicle may show drivability concerns, higher fuel use, increased exhaust output, or a malfunction indicator light. Walker Products 350-64052 is a direct-fit option for drivers servicing a Honda HR-V upstream oxygen sensor, a Honda Accord upstream oxygen sensor, or a Honda Civic front oxygen sensor application.

What It Helps Address

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

Installation Notes

Verify the connector style, thread diameter, and upstream position before installation. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion, since physical damage can shorten sensor life. Confirm the vehicle application against the listed fitment before replacing the original part.
