EVIL ENERGY Downstream Oxygen O2 Sensor 234-4260 for 2003-2014 LEXUS ES350 LX570 GX460 LX470 GX470 3.5L 4.6L 4.7L 5.7L for 2003-2016 TOYOTA 2.4L 2.7L 3.5L 4.0L 4.6L 4.7L 5.7L in Oxygen.. FUNCTION:O2 sensors are designed to monitor the amount of oxygen that's in your car's exhaust stream, as a marker of efficiency and to confirm the catalytic converters function properly. They sense whether your engine is running an air/fuel mixture that is too rich or too lean by burning a portion of the oxygen as it comes through the exhaust system. A voltage signal that is sent back to the engine control computer, which then adjusts fuel metering and timing to maintain an optimum mixture. 。 FEATURE:EVIL ENERGY O2 sensor can improve engine performance and greater fuel efficiency and prevent premature sensor failure 。 LOCATION of CAR OXYGEN SENSOR:Newer vehicles will have more than one sensor—one “upstream" and one “downstream." The upstream sensor will be on the exhaust pipe, closer to the engine, while the downstream sensor is situated closer to the muffler and catalytic converter; the idea is to fine-tune the input the engine computer receives by getting two readings. V6 and V8 cars and trucks with dual exhaust will have sensors for each exhaust pipe (four sensors). 。 OXYGEN SENSORS LIFETIME: The older cars from the '80s and early '90s had oxygen sensors that were only good for about 60k miles, cars after '96 can easily go 100k miles or more before the sensor needs replacement. They are incredibly rugged, considering that they are constantly subject to horrendous temperatures and conditions. 。 APPLICATION: Downstream o2 Oxygen Sensor #234-4260 fit for 2003-2014 LEXUS ES350 LX570 GX460 LX470 GX470 3.5L 4.6L 4.7L 5.7L and for 2003-2016 TOYOTA TUNDRA AVALON TACOMA 4RUNNER CAMRY SEQUOIA VENZA FJ CRUISER LAND CRUISER SOLARA 2.4L 2.7L 3.5L 4.0L 4.6L 4.7L 5.7L 。
