and that the ground is present at PIN 5, if present correctly replace the handle sensor, if not
present check the continuity of the malfunctioning cable: if the continuity is present replace
the control unit, if not present replace the wiring harness
DIAGNOSTIC TOOL: LOGIC ERRORS
P1227 Tracks A-B handle position sensor
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
INTAKE AIR PRESSURE SENSOR
Function
The pressure sensors (one per cylinder) are es-
sential not only for the injection map at low an
stabilised speeds, but also for the Ride by Wire
system control: their signal is introduced in a TOR-
QUE CHIN to check the correct opening of the
throttle valves.
Operation / Operating principle
Membrane sensor that converts the membrane
position, in contact with the intake air, to electric
voltage.
