NOTESSpecial notes:
When this fault arises, the engine is noisy and a light smoke appears.
See the Technical Note Wiring Diagrams for the vehicle.
IMPORTANT
The Inlet air temperature sensor is absent when the engine is fitted with a flow sensor. In this case, its value is not
a true representation and is fixed on the following engines: K9K766, K9K724 in Vdiag 4C and 50.
It will always be absent on K9K 766, 768, 724 in Vdiag 48, as well as on K9K 768 Vdiag 4C and 50.
ENGINE: K9K 750
Move the wiring between the computer, component code 120 and the injection air temperature and pressure
sensor, component code 1474 to see if the status changes (present stored).
Look for any wiring damage and check the connection and condition of the inlet air temperature and pressure
sensor, component code 1474 and its connections.
If the connector is faulty and there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
If the resistance of the air temperature sensor is not:
15614 Ω ± 828 Ω at -20

replace the air temperature sensor.
Check the insulation and continuity of the following connections:
–3KQ between components 1474 and 120,
–3LQ between components 1474 and 120,
–3LN between components 1474 and 120.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
If the fault is still present, replace the inlet air temperature and pressure sensor, component code 1474.
If the fault is still present, contact the Techline.
