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 350-34396 is built for the correct application and fitment position, helping the vehicle’s ECU receive the signal it expects from the downstream sensor circuit. For search relevance, this is a Walker oxygen sensor for 1994 Buick Regal downstream replacement needs, and it is also referenced as Walker 350-34396.
This sensor line is part of Walker Products’ engine management and oxygen/air-fuel sensor program, which is aimed at direct replacement applications where connector style, harness length, thread size, and sensor type must match the vehicle. The 1994 Buick Regal downstream oxygen sensor application depends on accurate exhaust feedback, and this part number is specified for that position.
What It Helps Address
- Check engine light related to downstream oxygen sensor faults
- Poor fuel economy caused by incorrect exhaust feedback
- Rough engine operation tied to sensor signal issues
- Elevated exhaust emissions from a failing oxygen sensor
- Stored ECU fault codes linked to the affected sensor circuit
Installation Notes
Verify the connector shape, wire count, thread diameter, and harness length before installation. Inspect the sensor wiring harness and connector for physical damage, since damaged wiring can shorten service life and affect signal quality. This part installs in the threaded downstream position on the 1994 Buick Regal and should be matched to the vehicle’s original sensor location and connector style.
Quality Assurance
Walker Products states that its engine management sensors are manufactured for specific applications and fitment positions, with feedback calibrated for ECU requirements. The company also notes ISO 9001/TS 16949 certification and long-term experience in engine management and fuel system components. This part cross-references OE-style replacement needs for the same application.
