AIR FUEL RATIO (A/F) SENSOR [SKYACTIV-D 1.8]
id0140s1004800
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 sends 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
• Sends the signal, which fluctuates according to the oxygen concentration (all-range air/fuel ratio), to the PCM.
