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 no 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.
AXONE: 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 Axone if the temperature indicated is plausible
in relation to 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
Air temperature sensor
INTAKE AIR TEMPERATURE SENSOR
Function
It tells the control unit the intake air temperature in
order to calculate oxygen presence so as to opti-
mise the petrol quantity necessary for correct com-
bustion.
Operation / Operating principle
NTC type sensor (resistance sensor, inversely
variable with temperature).
