Oxygen Air Fuel Ratio Sensor

The oxygen sensor or air fuel ratio sensor before the catalytic converter is used by the ecm to adjust the air fuel ratio.

Oxygen air fuel ratio sensor.

If there is any problem with the sensor it can send a bad or false signal to the computer which can throw off its calculations and cause it to waste fuel excessively. An air fuel ratio meter monitors the air fuel ratio of an internal combustion engine also called air fuel ratio gauge air fuel meter or air fuel gauge it reads the voltage output of an oxygen sensor sometimes also called afr sensor or lambda sensor. It is constructed from durable material that is corrosion and abrasion resistant. The exterior appearance of the air fuel ratio sensor and oxygen sensor may be very similar but that s where the similarity stops.

Denso air and fuel ratio sensor is designed to detect the amount of the exhaust gas air and fuel ratio. Narrow range oxygen sensor typically called an oxygen o2 sensor wide range oxygen sensor typically called an air fuel ratio a f sensor. Check here for special coupons and promotions. Order oxygen air fuel ratio sensor for your vehicle and pick it up in store make your purchase find a store near you and get directions.

This sensor in obd ii terms is referred to as sensor 1. 888 800 9629 0 0 00 us my account login. The two most common are listed below. The original narrow band oxygen sensors became factory installed standard in the late 1970s and early 1980s.

The coat of soot on this unheated oxygen sensor reduces its sensitivity to changes in the air fuel mixture ratio. Live customer service technical support. 2016 denso air fuel sensor and oxygen sensor catalog. A contaminated sensor will not produce an accurate signal or generate an accurate air fuel mixture reading.

To contact them click here. This sensor features zirconia solid electrolyte integrated with alumina heater substrate which precicely controls the amount of oxygen concentration that flows. A f sensors fall prey to the same ailments as ordinary o2 sensors. We are not denso.

The air fuel ratio sensor receives voltage from the vehicle s ecu and. The air fuel ratio sensor monitors the oxygen content in the exhaust stream and sends data to the computer so that it can add or subtract fuel. A using a light bulb analogy the oxygen sensor sends voltage to the vehicle s ecu and acts like an on off switch turning the bulb on and off.
