Oxygen air fuel ratio sensor.

Narrow range oxygen sensor typically called an oxygen o2 sensor wide range oxygen sensor typically called an air fuel ratio a f sensor. The oxygen sensor or air fuel ratio sensor before the catalytic converter is used by the ecm to adjust the air fuel ratio. 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.

A contaminated sensor will not produce an accurate signal or generate an accurate air fuel mixture reading. The air fuel ratio sensor receives voltage from the vehicle s ecu and. 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.

This sensor in obd ii terms is referred to as sensor 1. The coat of soot on this unheated oxygen sensor reduces its sensitivity to changes in the air fuel mixture ratio. 888 800 9629 0 0 00 us my account login. The original narrow band oxygen sensors became factory installed standard in the late 1970s and early 1980s.

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. To contact them click here. The two most common are listed below. Denso air and fuel ratio sensor is designed to detect the amount of the exhaust gas air and fuel ratio.

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. 2016 denso air fuel sensor and oxygen sensor catalog. This sensor features zirconia solid electrolyte integrated with alumina heater substrate which precicely controls the amount of oxygen concentration that flows. Oxygen sensor construction and operation the oxygen sensor sometimes referred to as heated oxygen sensor ho2s or o2s has been in service the longest.

We are not denso. On v type engines one sensor will be referred to as bank i sensor 1 and the other as bank 2 sensor 1. Your order may be eligible for ship to home and shipping is free on all online orders of 35 00.
