Walker Products 250-54085 oxygen sensor for the 2012-2015 Toyota Tacoma V6 4.0L and other vehicles measures the oxygen in the exhaust gas to track combustion efficiency. This Walker Products oxygen sensor passes that reading to the engine computer, which uses it to fine-tune the air-fuel mixture.
A failing sensor can show up as rough running, higher fuel consumption or a lit malfunction indicator light. A fouled spark plug, an exhaust leak or damaged wiring can be behind the same signs, so find the cause before buying. With the engine off and cool, look over the sensor, harness and connector for physical damage.
Among the many vehicles it fits are the 2011-2014 Toyota Tundra V6 4.0L, the 2013-2021 Tundra V8 5.7L and the 2014-2019 Tundra V8 4.6L, and it is an oxygen sensor for the 2013 Lexus IS250 V6 2.5L as well.
