There is a problem at the injection end.
Refer to the injection fault finding procedure which corresponds to the vehicle.
Check the continuity and absence of short circuits of the electrical wiring.
Repair if necessary.
Check that 12 volts is present on tracks 2 and 17 of the air conditioning control
unit 30-way connector.
Is 12 volts present?
YES There is a problem at the injection end.
Refer to the injection fault finding procedure which corresponds to
the vehicle.
NO Check whether the evaporator temperature sensor is in place.
Check its resistance: disconnect the evaporator temperature sensor
and measure the resistance at its terminals. The resistance measured
should be between 90 ohms and 13.7 kohms.
If the evaporator temperature sensor is in good condition, change
the air conditioning control unit.
If the evaporator temperature sensor is not in good condition,
change it.
