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.
