In this video we show How to replace the oxygen (O2) sensor also known has Air Fuel Ratio sensor on the Nissan Frontier V6 (3300 – VG33E) engine.Here you will see the difference between Bank #1 (right side)and Bank #2(left side) heated (4-wire) oxygen sensors. Replacing the oxygen sensor every 60-70,000 miles is an effort to help conserve fuel/gasoline.The oxygen sensor are not the only device to harness against waste consumption. The coolant temperature sensor at the thermostat housing reports to the computer, the computer commands the cooling fans through the fuel/relay box. Some model will be equipped with dual cooling fans. One for normal operation is the 1st fan. The 2nd fan is for air condition operation and over-heating conditions. If the Tstat remain stuck “close” the two fan will operate and coolant will overflow in its reserve container. The Tstat ONLY control engine temperature. The fans operation and gauge help radiates any heat or over heating base on ambient air temperature and operator.
The oxygen sensor is a state EPA “enviromental term” all so known has a EGT – exhaust gas temperature sensor sends millivoltage(data) to the ecm – engine control module for fuel injector control and its flow rate(impedeance). The oxygen sensor key roll is to measure the combustion flame/temperature .the ideal temperature for anything above 75% throttle is .870mv – .900mv output at the exhaust gas temperature/oxygen sensor. The oxygen(o2) sensor also work in conjuction with the Mass Air Flow Meter/sensor for fuel injector control. So the oxygen sensor can also be conside a Air Fuel Ratio sensor and the Mass Air Flow meter is mounted on the intake manifold duct.
M18 sensors – Install finger tight then 1/2 – 3/4 turn with wrench/ O2 sensor socket.26-33ft. lbs
M12 sensors – Install finger tight then 3/4 – 1 turn with wrench / O2 sensor socket.13.2-17ft. lbs.
APPLICATION: 2003 NISSAN FRONTIER EX, Xterra

* DO NOT drop or use an oxygen sensor that has been dropped as this may have caused shock damage to the ceramic cell.
* DO NOT use any compound on or around the sensor unless labeled as oxygen sensor friendly products.
* DO NOT use impact wrench or conventional socket type wrench to install sensor.
* DO NOT allow sensor or lead wire to touch exhaust manifold or any other hot component.
* DO NOT expose this product to water,oil,windshield cleaner, anti-corrosion oil,grease,terminal cleaner, etc.
* DO NOT use leaded fuels, silicone or metal based additives
* DO NOT store under high humidity conditions will promote rusting.
WARNING : Anti-seize compound may cause irritation to the skin or eyes. In case of contact, wash affected area with soap and water. In case of eye contact, Flush with water for 15 minutes. If irritation persists, consult a physician. If swallowed, DO NOT induce vomiting.
