AIR FUEL RATIO (A/F) SENSOR [SKYACTIV-D 2.2]

id0140z7004800


Purpose/Function

•  Detects the oxygen concentration (all-range air/fuel ratio) in the exhaust gas as basic information for mainly determining the EGR amount.
•  Detects the oxygen concentration (all-range air/fuel ratio) in the exhaust gas and inputs it to the PCM as an oxygen concentration (all-range air/fuel ratio) signal.

Construction

•  Installed on the rear side of the catalytic converter.

•  A zirconium element has been adopted as the detecting element for detecting the oxygen concentration (all-range air/fuel ratio).

Operation

•  Inputs the signal, which fluctuates according to the oxygen concentration (all-range air/fuel ratio), to the PCM.
