Product Details

Walker Products Aftermarket 350-31014 is part of the Walker Products Engine Management line, which focuses on replacement sensors built for application-specific fitment and ECU feedback requirements. This oxygen sensor is intended for the upstream location on 1980-1983 Volkswagen Vanagon models and is listed for Bank 1 Sensor 1 service on those vehicles. The design details, including the non-heated sensor type, threaded mount, and connector configuration, support direct replacement where the original sensor uses the same style and placement. Walker Products 350-31014 is also referenced by the part number 350-31014 for catalog and search use.

Common Issues This Sensor May Address

• Check engine light or malfunction indicator light related to oxygen sensor performance
• Rough engine operation caused by incorrect exhaust feedback
• Increased fuel consumption from inaccurate air-fuel monitoring
• Higher exhaust emissions from a failing upstream sensor
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes and Tips

Confirm the original sensor connector, thread size, and upstream mounting location before installation. Inspect the sensor wiring harness and connector for heat damage, corrosion, or abrasion, since physical damage can shorten service life. For Volkswagen Vanagon oxygen sensor replacement, verify that the vehicle uses the same non-heated configuration and Bank 1 Sensor 1 upstream position before ordering. The part number 350-31014 should be matched to the vehicle’s original sensor layout and ECU requirements.
