Together with the overfeed pressure sensor, this N.T.C. type sensor located on the intake manifold input downstream
the intercooler on the engine left supplied the electronic center with the parameters required to identify proper air
delivery values.

This pressure strain gauge transducer located on the intake to the intake manifold downstream the intercooler on the
engine left side measures air overfeed pressure to the intake manifold.
This measurement, together with the air temperature sensor finding, enables the electronic center to exactly define
the amount of air admitted to the cylinders so as to pilot injectors by adjusting fuel supply, limit noxious emissions and
improve fuel consumption and engine performance.
The sensor is provided with an internal temperature correction electronic circuit to optimize pressure measurement
as a function of admitted air temperature.

This induction type sensor located on the flywheel generates signals obtained from the magnetic flow lines that close
through 54 holes in three series of 18 in the flywheel.
The electronic center uses this signal to detect the various engine ratings and pilot the electronic rev counter.
The rev counter does not operate in the absence of this signal.
This sensor’s air gap is NOT ADJUSTABLE.

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.
Though electrically identical to (48035) engine rpm sensor mounted in the camshaft in is NOT interchangeable with
it as it cable is shorter and it features a larger diameter.
This sensor’s air gap is NOT ADJUSTABLE.
