Walker 350-35149 sensor for the 2019-2024 Volkswagen Jetta 1.4L and other vehicles is a heated, wide-band oxygen sensor that measures the amount of oxygen in the exhaust gas.
A failing oxygen sensor can show up as an engine that runs poorly, higher fuel use, more exhaust emissions or a lit malfunction indicator light. Before you replace the sensor, rule out physical damage to its wiring harness and connector, and have the stored fault codes read, since they can point to another part of the system.
This Walker oxygen sensor also fits the 2019-2021 Volkswagen Golf 1.4L and the 2017-2026 Porsche Panamera 2.9L. The 2019-2021 Volkswagen Golf 1.4L takes one sensor. If your car isn't named here, find it on the Buyer's Guide tab.
