DIAGNOSIS INSTRUMENT: PARAMETERS
Engine temperature:
•
Example value with key ON: 25° C
•
Example value with engine on: 75° C
•
In case of recovery, this value is set by the control unit: if there is a malfunction after engine
start-up, temperature decreases up to approximately 75°.
Engine temperature pre Recovery:
•
Example value with key ON: -40° C
•
Example value with engine on: -40° C
•
Value drawn from the signal read without taking into account any recovery: the value in the
example refers to an open circuit.
Engine temperature at start-up:
•
Example value with key ON: -40° C
•
Example value with engine on: 25° C
•
The temperature value is stored during engine start-up. With key ON, value -40°C is read.
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.
DIAGNOSIS INSTRUMENT: 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 12 of
the ENGINE connector. If shorted to negative: voltage equal to zero has been detected. The
instrument panel does not indicate the presence of this error even in the ATT status.
Troubleshooting
•
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 OK,
check continuity between the ENGINE connector PIN 12 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 OK, it means that the error cause is that the cable is shorted to positive
and it is necessary to restore the cable harness between ENGINE PIN 12 and 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
