Electrical system
example value: 75° C
In case of recovery, this value is set by the control unit.
Engine Temp. before Recovery
example value: -40° C
Value drawn from the signal read without taking into account any recovery: the value in the example
refers to an open circuit.
NAVIGATOR: ELECTRICAL 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 45 of
the ENGINE connector. If shorted to negative: voltage equal to zero has been detected at
PIN 45 of the ENGINE connector.
•
If the circuit is open, shorted to positive: check the sensor connector and the Marelli control
unit connector. If they are OK, check sensor continuity: replace the sensor if not OK; if it is
OK, check the continuity between the ENGINE connector PIN 45 and the sensor PIN 1:
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 2 and
the vehicle ground connection: if it is correct, it means that the error cause is that the cable
is short circuit to positive and it is necessary to restore the cable harness between the EN-
GINE PIN 45 and the sensor PIN 1; if there is no continuity with the ground connection,
check the sensor connector and the Marelli control unit connector. If not OK, restore the
cable harness. If OK, check continuity between the ENGINE connector PIN 35 and the sen-
sor connector PIN 2: restore the cable harness if there is not continuity. If there is, it means
that the control unit does not supply the ground connection and therefore should be replaced.
Troubleshooting
•
If shorted to negative, check sensor correct resistance: if resistance is null, replace the sen-
sor; if resistance is correct, it means that the cable has ground connection: restore the cable
harness.
NAVIGATOR: LOGIC ERRORS
engine temperature sensor P0116 - signal not valid.
Error cause
•
An excessive temperature variation has been detected: for example, the cause may be a
contact resistance between the terminals.
Troubleshooting
•
Check the sensor connector and the ENGINE connector of the Marelli control unit.
NOTES No error is detected if the sensor does not work correctly or the control unit connector
or sensor terminals are rusty: then check through Navigator if the temperature indicated is the
