Troubleshooting
•
An interruption in the sensor circuit has been detected, from PIN 20 to PIN 29 of the control
unit connector.
•
Check the sensor connector and the injection ECU connector:
•
If the values are incorrect restore them.
•
If the values are correct, check the continuity of the two cables that go from PIN 20 to PIN
29 of the control unit connector:
•
If there is no continuity, restore the cabling.
•
If there is continuity check interruption in the sensor and replace it.
Short circuit.
•
Conduct an electrical check of the sensor.
•
If the sensor check value is incorrect replace it.
•
If the value is correct, check insulation of the power from ground of the two cables.
•
Conduct tests from the sensor connector toward the sensor.
•
If the sensor value is incorrect restore the cabling/replace the sensor.
•
If the value is correct conduct tests from PIN 20 and 29 of the Marelli control unit connector
toward the cable harness.
Installation
Place the sensor plus the corresponding spacers; the air gap should be between 0.7 and 0.9 mm.
Engine temperature sensor
Function
indicates the engine temperature to the control unit
so as to optimise carburetion and idle control
Operation / Operating principle
