Electrical system
•
If the circuit is open, short circuit to negative, check filter box large connector, the Marelli
control unit connector and the sensor connector. If not OK, restore. If everything is OK, and
with key set to OFF, check if there is continuity between the VEHICLE PIN 34 of the Marelli
control unit and the sensor connector PIN 3: if there is no continuity, restore the cable har-
ness. If there is continuity, check the cable ground insulation: if there is continuity to ground,
restore the cable harness; if not, with key set to ON check that the voltage on sensor con-
nector PIN 1 is approx. 5 V: if this is not correct, set the key to OFF and check continuity
between the ENGINE connector PIN 15 and the sensor connector PIN 1: If not OK, restore
the cable harness; if it is OK, replace the control unit. if there is 5V voltage at PIN 1, and
with key set to ON, check the continuity to ground of the sensor connector PIN 3: if not OK,
restore the cable harness; if OK, replace the sensor.
Rear cylinder air pressure sensor P0106 -short circuit to positive / open circuit, short circuit to neg-
ative.
Error cause
•
If shorted to positive: excessive voltage has been detected at PIN 5 of the VEHICLE con-
nector.
•
If the circuit is open, shorted to negative: voltage equal to zero has been detected at PIN 5
of the VEHICLE connector.
Troubleshooting
•
If short circuit to positive, see that the parameter of the front Cylinder Intake Pressure on
the diagnosis instrument reads approx. 1200 mbar; disconnect the large connector from the
filter box: if the value does not vary, it means that the cable is short circuited between the
filter box connector and the control unit connector; restore the cable harness. If the value
varies, reconnect the filter box connector and disconnect the sensor connector: if the value
does not vary, it means that the cable is short circuited between the filter box connector and
the sensor connector; restore the cable harness. Replace the sensor if the value varies.

the cable harness; if it is OK, replace the control unit. if there is 5V voltage at PIN 1, and
with key set to ON, check the continuity to ground of the sensor connector PIN 3: if not OK,
restore the cable harness; if OK, replace the sensor.
