Walker Products Oxygen Sensor P/N:350-34354
Walker Products 350-341006 oxygen sensor for the 2017-2019 Toyota Highlander V6 3.5L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. This Walker Products oxygen sensor is a four-wire, narrow-band, direct-fit unit.
A failing sensor can show up as a rough-running engine, higher fuel use or a lit malfunction indicator light. A damaged wiring harness or connector can produce some of the same signs, so inspect both for physical damage and have the stored fault codes read before you buy a sensor. This listing is one sensor, and each listed engine takes one at this position.
This downstream oxygen sensor is a direct-fit part for the 2017-2019 Toyota Highlander V6 3.5L, the 2016-2022 Lexus RX350 V6 3.5L and the 2016-2022 Lexus RX450h V6 3.5L, among others. If your vehicle is not named here, look up your year, model and engine in the "Vehicles it fits" section.

What protects the electrodes in this oxygen sensor?
A coating on the electrode surfaces prevents contamination and erosion from combustion residue and particulates in the exhaust gases.
