Purpose/Function
• Detects the oxygen concentration (theoretical air/fuel ratio) in the exhaust gas as basic information for mainly determining the fuel injection amount and as information for determining the deterioration of catalytic converter.
• Detects the oxygen concentration (theoretical air/fuel ratio) in the exhaust gas and sends it to the PCM as an oxygen concentration (theoretical air/fuel ratio) signal.
Construction
• Installed on the rear side of the exhaust manifold.

• A zirconia element has been adopted as the detecting element for detecting the oxygen concentration (theoretical air/fuel ratio).
Operation
• Inputs the signal, which fluctuates according to the oxygen concentration (theoretical air/fuel ratio), to the PCM.
