THE CONNECTION DIAGRAMS ARE IN THE ELECTRICAL SYSTEM SECTIONS; PAY ATTENTION
TO THESE DIAGRAMS AS THEY SHOW THE CONNECTOR/COMPONENT AS VIEWED FROM
THE CABLE HARNESS SIDE, THAT IS LOOKING AT THE CABLES WHEN GOING OUT OF THE
"MAIN" CABLE HARNESS AND INTO THE CONNECTOR/COMPONENT.
CAUTION
BEFORE CARRYING OUT ANY TROUBLESHOOTING, CAREFULLY READ THE GENERAL TROU-
BLESHOOTING CONCEPTS FOR ELECTRICAL DEVICES AT THE BEGINNING OF THE CHECK
AND CONTROL SECTION IN THE ELECTRICAL SYSTEM CHAPTER.

Engine temperature
In case of recovery, this value is set by the control unit.
NAVIGATOR: ERRORS
engine temperature sensor P0115 - open circuit, shorted to positive / shorted to negative.
Error cause
•
If the circuit is open, shorted to positive: excessive voltage has been detected at PIN 5 of
connector A (BROWN).
•
If shorted to negative: voltage equal to zero has been detected at PIN 5 of the BROWN
connector.
Troubleshooting
•
If the circuit is open, shorted to positive: check the sensor connector and the Marelli control
unit connector. If they are not OK, restore the cable harness; if OK, check the continuity of
the sensor; if it is not OK, replace the sensor; if it is OK, check continuity between PIN 5 of
the BROWN connector and PIN 2 of sensor: restore cable harness if there is not continuity;
if it is OK, reconnect the control unit connector and, with key set to key ON, check the
continuity between the sensor connector PIN 1 and the vehicle ground connection: if there
is not continuity, restore the cable harness; if there is continuity, it means that the cause of
the error is that the cable is shorted to positive and now the cable harness between the
