Oxygen sensors are installed in 2 positions (front, rear) on catalytic converter. The
structure and operation is basically the same as that of the 6B31 - MPI - engine.

A crank angle sensor is installed in the cylinder block. The crank angle sensor monitors
rotation of crankshaft sensing blade (36 teeth including 3 missing teeth) installed on the crankshaft
and converts to voltage (pulse signal) that is output to engine-ECU. Engine-ECU uses crank angle
sensor’s output pulse to detect crankshaft position.
The structure is basically the same as that of the 6B31 - MPI - engine.

The inlet camshaft position sensor is installed on the cylinder head. The inlet camshaft
position sensor monitors shape of the half-moon sensing portion and converts to voltage (pulse signal)
that is output to engine-ECU. Upon receiving this output voltage, the engine-ECU effects feedback
control to optimize the phase of the inlet camshaft. Also, engine-ECU uses a combination of
the camshaft position sensor output pulse signal and crankshaft position sensor output pulse
signal to identify cylinders in the compression process.

The exhaust camshaft position sensor is installed on the cylinder head. The exhaust crankshaft
position sensor monitors shape of the half-moon sensing portion and converts to voltage (pulse
signal) that is output to engine-ECU. Upon receiving this output voltage, the engine-ECU effects
feedback control to optimize the phase of the exhaust camshaft.

The inlet or exhaust camshaft position sensor uses a magnetic resistance element. When
the crankshaft-sensing portion passes the front surface of the magnetic resistance element, the
flux from the magnet passes the magnetic resistance element. Thus, resistance of the magnetic
resistance element increases. When the crankshaft-sensing portion does not pass the front surface
of the magnetic resistance element, the flux from the magnet does not pass the magnetic resistance element
and the resistance decreases. The intake or exhaust camshaft position sensor converts this change
in resistance of the magnetic resistance element to a 5 V pulse signal and outputs it to engine-ECU.

A vehicle speed sensor is installed on the transmission. The vehicle speed sensor uses
Hall IC. The vehicle speed sensor monitors rotation of the speedometer drive gear installed
on the differential case and converts to voltage that is output to engine-ECU. Engine-ECU calculates
vehicle speed based on the vehicle speed sensor’s output frequency. Sensor properties are
as shown in the figure.
