Walker 350-34147 Oxygen Sensor Overview
Walker Products 350-34147 is a heated oxygen sensor built as a specific-fit OE replacement for the correct application and mounting position. It is engineered to deliver the ECU feedback needed for accurate fuel control, emissions monitoring, and fault detection.
Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors for a wide range of vehicles, with application-specific fitment and connector design. The 350-34147 follows that approach for service replacement on vehicles that use a threaded, 4-wire heated sensor.
Key Features
- Heated oxygen sensor for engine management and emissions feedback
- Specific-fit design for the intended vehicle application
- 4-wire configuration with 20-gauge wiring
- Radiused polygon connector shape with male and female connector genders listed in the application data
- Threaded mounting type with 18.0 mm thread diameter
- Wiring harness length: 64.29 in.; overall length: 67.83 in.
Detailed Product Description
The Walker 350-34147 oxygen sensor is built for vehicles that rely on a heated sensor to monitor exhaust oxygen content and send feedback to the ECU. When the sensor response slows or fails, the engine can run rich or lean, fuel economy can drop, emissions can rise, and the malfunction indicator light can illuminate. This part number is intended for direct replacement use where the original sensor uses the same threaded mounting, harness length, and connector style.
For buyers searching for a Walker oxygen sensor for Honda Civic service, or a Walker 350-34147 replacement for other specific-fit applications, this part is positioned as an OE-style service component rather than a universal sensor. It is also relevant for drivers diagnosing oxygen sensor fault codes, exhaust emissions issues, or drivability concerns tied to the sensor circuit.
What This Sensor Helps Address
- Check engine light related to oxygen sensor performance
- Poor fuel economy caused by incorrect air-fuel feedback
- Rough running or inconsistent engine operation
- Elevated exhaust emissions
- Stored ECU fault codes tied to the sensor or related circuit
Installation Notes and Tips
Verify connector shape, wire count, harness length, and thread diameter before installation. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion, since physical damage can shorten service life and affect signal quality. Confirm the mounting position and application details against the vehicle service information before replacing the original sensor.
Quality Assurance
Walker Products manufactures engine management sensors as OE-replacement components for specific applications and backs its product line with ISO 9001/TS 16949 certified manufacturing practices. This part number, 350-34147, reflects that application-focused approach for service replacement on the correct vehicle platform.
