CIRCUIT DESCRIPTION
The main oxygen sensor is located in the exhaust manifold.
It indirectly determines whether the fuel mixture is rich or lean by detecting the concentration of
oxygen present in the exhaust gas.
Engine speed varies by more than 15 rpm over
the preceding crank position period during a period
of 50 sec. or more under conditions (a) and (b).

5S±FE ENGINE
 DESCRIPTION
The 5S±FE engine has improved the torque in the low±to±mid±speed range through improvements made for the intake
and exhaust systems and the combustion chamber. In addition, its exhaust emissions have been reduced through the
improvements made for the exhaust system and the engine control system.
