Functional diagnosis:
•
Signal not congruent
Error cause:
•
Detected two voltages signals at PIN 39 and 13 of the ENGINE connector (tracks A-B)
This error is indicated by flashing the general warning light and by lighting up in a fixed manner the MI
warning light.
Troubleshooting:
•
Check the parameters for the track A and track B Handle position sensor. The values de-
tected on track A must be comprised between 1 V (gas throttle completely closed) and 4 V
(gas throttle completely open). The values detected on track B must be comprised between
0.5 V (gas throttle completely closed) and 2 V (gas throttle completely open). If one of these
values differs significantly from the indicated value, it means that the potentiometer is faulty.
check the handle sensor connector and control unit connector; if not OK, restore. If OK,
check that cable resistance between the handle sensor cable and the control unit is a few
tenths of Ohm; otherwise, restore the wiring harness; if ok, replace the complete handle
command.
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.
•
connector: on the sensor.
