Symptoms of a Bad or Failing Air Fuel Ratio Sensor Decrease in fuel efficiency. One of the first symptoms of a problem with an air-fuel ratio sensor is a decrease in fuel efficiency. Drop in engine power output. Another symptom of a possible problem with an air-fuel ratio sensor is a decrease in engine performance and power output. Rough idle. Click to see full answer. Simply so, can you clean air fuel ratio sensor?In general engine cleaner sprayer will do the trick of cleaning the air fuel ratio sensor. If you want to brush onto it, do it only gently on the outside. And do use some compressed air to clean the last drops of engine cleaner out after doing so.Furthermore, what does an air fuel ratio sensor do? The air fuel ratio sensor is installed in the exhaust manifold or in the front exhaust pipe, before the catalytic converter. The job of the air fuel ratio sensor is to measure the oxygen content in the exhaust and provide feedback to the engine computer (PCM). One may also ask, what causes bad air fuel ratio? If a bad oxygen sensor causes an engine’s air/fuel mixture to become too lean or restricted, the explosions within an engine’s cylinders (engine combustion) will be altered.What is the difference between air fuel ratio sensor and oxygen sensor?An air/fuel sensor can read a much wider and leaner range of fuel mixtures than a conventional O2 sensor. That’s why they’re also called “wideband” O2 sensors. Another difference is that A/F sensors don’t produce a voltage signal that suddenly changes on either side of Lambda when the air/fuel goes rich or lean.
