Two Ways to remove a broken key
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.
