This induction type sensor located on the camshaft generates signals obtained from the magnetic flow lines that close through
the 6 plus 1 phase teeth of a sound wheel mounted on the shaft.
The electronic center uses the signal generated by this sensor as an injection step signal.
This sensor’s air gap is NOT ADJUSTABLE.

Oil temperature/pressure sensor (42030 / 47032)
This component is identical to the air pressure/temperature
sensor and replaced single sensors 47032 / 42030.
It is fitted onto the engine oil filter, in a horizontal position.
It measures the engine oil temperature and pressure.
The measured signal is sent to the EDC control unit which
controls, in turn, the indicator instrument on the dashboard
(low pressure warning lights / gauge).

Air pressure/temperature sensor (85156).
This component incorporates a temperature sensor and a
pressure sensor.
IIt replaces the temperature sensors (85155) and pressure
sensors (85154) available in the preceding systems.
It is fitted onto the intake manifold and measures the
maximum supplied air flow rate used to accurately calculate
the amount of fuel to be injected at every cycle.
The sensor is powered with 5 V.
The output voltage is proportional to the pressure or
temperature measured by the sensor.

Fuel pressure sensor on rail
Installed on one rail end, it measures actual fuel pressure in order to determine injection pressure.
The injection pressure value is used for pressure check and to determine the injection electric command duration.
It is supplied with 5 volts.
It is connected to ECU on pins 12C - 13C - 14C.
