Walker 350-34359 Oxygen Sensor - Downstream

Walker Heated Oxygen Sensor for 1996 Corsica

Walker Products 350-34359 is a specific-fit heated oxygen sensor engineered as an OE-style replacement for the exhaust monitoring system. It is built for downstream placement on the 1996 Chevrolet Corsica and is designed to provide the ECU with the feedback needed for accurate fuel control and emissions monitoring.

Key Features

• Heated oxygen sensor for downstream exhaust monitoring
• Specific-fit design for the listed application
• 4-wire configuration with a 20-gauge harness
• Threaded mounting with an 18.0 mm thread diameter
• Radiused polygon connector shape with male connector gender
• Wiring harness length: 70.39 in.; overall length: 73.94 in.
• Walker Products Aftermarket part number 350-34359

Product Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors built for direct replacement use in vehicle-specific locations. Part number 350-34359 is made for the downstream position on the 1996 Chevrolet Corsica, including the downstream bank 1 sensor 2 application noted in fitment data. This sensor helps the ECU monitor exhaust oxygen content so the engine management system can maintain proper air-fuel control and emissions performance. The Walker Products 350-34359 is also identified by the part number 350-34359 for catalog and service lookup.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Illuminated malfunction indicator light related to oxygen sensor performance
• Poor engine operation caused by inaccurate exhaust feedback
• Increased fuel consumption from incorrect air-fuel correction
• Higher exhaust emissions from a failing downstream sensor
• Fault codes stored in the ECU for the affected sensor circuit

Installation Notes

Verify the connector, wiring harness, and sensor location before installation. Check the existing harness and connector for physical damage, since damaged wiring can shorten sensor life and affect signal quality. Confirm threaded mounting and sensor position on the vehicle before replacing the unit. For 1996 Chevrolet Corsica service work, confirm the downstream bank 1 sensor 2 location matches the vehicle’s exhaust layout.

Quality Assurance

Walker Products has supplied engine management and fuel system components since 1946 and operates as an Automotive ISO9001/TS 16949 certified company. The 350-34359 oxygen sensor is manufactured for the specified application and fitment position to deliver the diagnostic feedback expected by the ECU.
