Front Oxygen Sensor EJ20 22690AA900 Forester EJ253 MY06 ATThis sensor measures the oxygen content in the exhaust system pre catalyst. An oxygen sensor (or AF sensor) can establish the air fuel ratio by measuring the excess oxygen left over from the combustion process. The front air fuel (AF) sensor is used by the ECU for fuel calculations during closed loop fueling. A faulty sensor can result in poor engine operation or stalling and may set a CEL.
