If open circuit, short circuit 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 OK,
check continuity between the ENGINE connector PIN 12 and the sensor PIN 3: If continuity
is absent, restore the wiring harness; if ok reconnect the control unit connector and with key
ON check the continuity between PIN 1 of the sensor connector and vehicle ground: if OK,
it means that the error is caused by the cable being shorted to positive and it is necessary
to restore the cable harness between ENGINE PIN 12 and sensor PIN 3; if there is no
continuity to ground, check the sensor connector and the Marelli control unit connector. If
not OK, restore the cable harness. If OK, check for continuity between the ENGINE con-
nector PIN 6 or 17 and the sensor connector PIN 1: 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.
•
If short circuit to negative, check the correct resistance of the sensor: if resistance is null,
replace the sensor; if resistance is correct, it means that the Yellow/Brown cable has ground
connection: restore the cable harness
DIAGNOSTIC TOOL: LOGIC ERRORS
P0116 Engine temperature sensor
Signal not plausible.
Error cause
•
An excessive temperature variation was detected: the cause could be a contact resistance
between the terminals, for example. The instrument panel indicates this error by lighting up
in a fixed manner the MI warning light.
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 use the diagnostic tool to check if the temperature indicated is the same as the engine
temperature. Check also that the sensor electrical characteristics are observed: replace the sensor if
not OK; if it is OK, check the sensor connector and the Marelli control unit connector.
