Electrical system
Intake pressure sensor
Function
The pressure sensors (one per bank), are funda-
mental for calculation of generated torque, for cal-
culation of ambient pressure and for correct
ignition timing during start-up.
Operation / operating principle
Diaphragm sensor which translates the diaphragm
position into electrical voltage when in contact with
the intake air.
Level in wiring diagram:
Intake air temperature sensor
Location:
•
on the vehicle: sensor for rear cylinders
(1 and 3) on the right of the filter box,
sensor for front cylinders (2 and 4) on
the left of the filter box.
