NTK Air / Fuel Ratio Sensor P/N:27071
NGK O2 SENSORS 24325 air / fuel ratio sensor for the 2017-2021 Honda Civic 4-cylinder 2.0L and other vehicles sends the ECU a linear rich-or-lean signal. Unlike a conventional switching sensor, which only reports rich or lean, a wideband sensor lets the ECU adjust the air-fuel mixture continuously.
An exhaust leak, a vacuum leak, a misfire or damaged wiring can produce rough running, poor fuel economy or a check engine light just as this sensor can, so find the cause before buying one. The 2017-2021 Honda Civic 4-cylinder 2.0L takes one sensor.
The 2015-2020 Ford F-150 V6 2.7L, the 2017-2020 F-150 V6 3.5L and the 2017-2019 Ford Escape 4-cylinder 1.5L take this sensor, and so do many other vehicles. Other vehicles are listed under the "Vehicles it fits" section, so look up your car's year and engine there.
