Walker Products 350-34112 oxygen sensor for the 2010 Volkswagen Jetta 4-cylinder 1.8L and other vehicles reads the oxygen in the exhaust gas to show how efficiently the engine burns fuel. It is a narrow-band, 4-wire sensor that gives the ECU the feedback it needs.
A failing sensor can show up as rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light. Those signs alone do not prove the sensor is the problem, since a vacuum leak can cause some of them too. With the engine off, look over the sensor, wiring and connector for damage.
This direct-fit sensor suits the 2000-2005 Volkswagen Passat 4-cylinder 1.8L, the 2018-2024 Volkswagen Saveiro 4-cylinder 1.6L and a wide range of Volkswagen, Audi and Porsche models. The fitment lists one sensor per application, and this listing is a single sensor. If your car is not named here, find its year and engine on the Buyer's Guide tab.

What does the coating on this oxygen sensor's electrodes do?
The electrodes carry a gas-permeable platinum layer. A coating guards the electrode surfaces against contamination and erosion from combustion residue and particulates in the exhaust.
Can a bad 4-wire oxygen sensor turn on the malfunction indicator light?
Yes, a failed sensor might cause poor running, higher fuel use, more emissions or a lit malfunction indicator light, and the ECU may store a fault code; its wiring and connector should also be checked for damage.
