What is the purpose of the oxygen sensor in the exhaust system on Nissan Frontier?

The oxygen sensor in the exhaust system reacts with the oxygen in the exhaust to produce a voltage output that varies depending on the oxygen content. This feedback signal is used by the PCM to determine the needed fuel injector pulse width and control the air/fuel ratio. The ideal ratio for emissions, fuel economy, and engine performance is 14.7 parts air to 1 part fuel. The post-converter oxygen sensor on this car is used for the catalyst monitor system and produces a slower fluctuating voltage signal. The PCM can detect oxygen sensor problems and set diagnostic trouble codes. To test the sensor, backprobe the signal wire terminal of the oxygen sensor connector and monitor the voltage. While pre-converter should switch actively between 0.1 and 0.9 volts, post-converter should also range from 0.1 to 0.9 volts but not switch actively . Check battery voltage supply and ground circuits to heater of oxygen sensor, check resistance of heater . In case an open circuit or excessive resistance is indicated then replace a faulty Oxygen Sensor . When replacing a sensor ensure that exhaust system has cooled properly follow proper handling procedures . Raise vehicle, disconnect electrical connector, unscrewed using a suitable wrench or socket, apply anti-seize compound at threads and tighten securely . Lower vehicle and reconnect electrical connector.

Nissan Frontier Oxygen Sensor

The Nissan Frontier Oxygen Sensor keeps tabs on the oxygen in exhaust gases so that the engine computer can manage the air and fuel mixture correctly to ensure combustion efficiency and low emissions. This zirconium dioxide element has platinum electrodes and ceramic insulating material and is covered with a threaded steel shell installed in the exhaust stream. Admitting hot gases from openings near the tip and outside air through upper vents, once the internal heater raises the temperature to about 600°F, the element produces between roughly 0.1 and 0.9 volt that vary with oxygen content. Each Oxygen Sensor utilizes a heater to ensure a faster warm-up period. Moreover, the voltage pattern observed at the Oxygen Sensor should swing rapidly between the rich and lean voltages. This feedback enables the control module to adjust the injector pulse width in the closed loop, resulting in cleaner exhaust and optimum catalyst efficiency. At minimum, every Nissan Frontier utilizes two sensors, one before the catalytic converter and one after the catalytic converter, with the latter functioning as a catalytic monitor. A malfunctioning or slow Oxygen Sensor inhibits feedback, which increases emissions. That is why installing a functioning Oxygen Sensor that is the same design as that applied by Nissan on the assembly line and meets Nissan specifications is the way to keep Frontier performance and fuel economy on target for virtually any Frontier model.

If you need any OEM Nissan Frontier Oxygen Sensor, feel free to choose them out of our huge selection of genuine Nissan Frontier Oxygen Sensor. All our parts are offered at unbeatable prices and are supported by the manufacturer's warranty. In addition, we offer quick shipping to have your parts delivered to your door step in a matter of days.
