Walker 350-32022 Oxygen Sensor - Upstream

Walker 350-32022 Oxygen Sensor Overview

Walker Products 350-32022 is a specific-fit oxygen sensor engineered as an OE-style replacement for vehicles that rely on accurate exhaust feedback to the ECU. With a non-heated, 2-wire design, 18.0 mm threaded mounting, and a radiused polygon female connector, it is built for direct application use where the original sensor matches these specifications.

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors for precise fitment and diagnostic feedback. For drivers servicing a Honda Civic or similar application, this sensor is selected to restore proper signal input when the original unit is no longer responding correctly.

Detailed Product Description

This Walker oxygen sensor is built for vehicles that require a non-heated, threaded exhaust sensor with the listed connector and harness configuration. The sensor sends exhaust oxygen feedback to the ECU so the engine management system can adjust fueling and monitor emissions performance. When the original sensor is worn or damaged, the vehicle may store fault codes and the engine may run outside normal calibration.

Walker Products 350-32022 is designed for direct replacement use on the specified application, making it a practical choice for repair work on models such as Honda Civic where the original sensor layout matches the connector, thread size, and wire configuration. The Walker Products Aftermarket line is focused on engine management components built around application-specific fitment.

What This Sensor Helps Address

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

Installation Notes and Tips

Confirm the original sensor uses a non-heated, 2-wire layout with an 18.0 mm threaded mount before ordering. Inspect the wiring harness and connector for heat damage, corrosion, or broken terminals, since physical damage can shorten sensor life and affect signal quality. Verify connector shape and harness length against the vehicle’s original routing before installation.

For fitment-based searches, this part is commonly referenced for Honda Civic oxygen sensor replacement needs when the original equipment configuration matches the listed specifications. Part number 350-32022 should be matched to the vehicle’s sensor position and connector style before installation.
