Air Fuel Ratio Sensor 1 No Activity Detected Bank 2
– Air fuel ratio (A/F) harness is open or shorted
– Air fuel ratio (A/F) poor electrical connection
– Possible rough
The A/F sensor is a planar dual-cell limit current sensor. The sensor element of the A/F sensor is the combination of a Nernst concentration cell (sensor cell) with an oxygen-pump cell, which transports ions. It has a heater in the element.
The sensor is capable of precise measurement
