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.

Oxygen air fuel ratio sensor.

Check here for special coupons and promotions. The original narrow band oxygen sensors became factory installed standard in the late 1970s and early 1980s. 2016 denso air fuel sensor and oxygen sensor catalog. Denso air and fuel ratio sensor is designed to detect the amount of the exhaust gas air and fuel ratio.

The coat of soot on this unheated oxygen sensor reduces its sensitivity to changes in the air fuel mixture ratio. Oxygen sensor construction and operation the oxygen sensor sometimes referred to as heated oxygen sensor ho2s or o2s has been in service the longest. 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. The exterior appearance of the air fuel ratio sensor and oxygen sensor may be very similar but that s where the similarity stops.

The oxygen sensor or air fuel ratio sensor before the catalytic converter is used by the ecm to adjust the air fuel ratio. This sensor in obd ii terms is referred to as sensor 1. 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. We are not denso.

The two most common are listed below. On v type engines one sensor will be referred to as bank i sensor 1 and the other as bank 2 sensor 1. 888 800 9629 0 0 00 us my account login. To contact them click here.

Narrow range oxygen sensor typically called an oxygen o2 sensor wide range oxygen sensor typically called an air fuel ratio a f sensor. Live customer service technical support. 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. 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.

The air fuel ratio sensor receives voltage from the vehicle s ecu and. It is constructed from durable material that is corrosion and abrasion resistant. A contaminated sensor will not produce an accurate signal or generate an accurate air fuel mixture reading.
