NOTESDepending on the engine type, the air temperature is given by the air temperature
sensor, which is either on the air flowmeter or in place of the air flowmeter on K9K 724,
740, 766, 768, and 812 engines only.
See the Technical Note Wiring Diagrams for the vehicle.
The air temperature sensor in the flow sensor has a separate electrical circuit.
Move the wiring between the computer and the air temperature sensor to see if a change of status occurs
(present stored).
Look for any wiring damage and check the connection and condition of the air temperature sensor and its
connections.
Check the connection and condition of the injection computer connector.
If the connector(s) is faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Measure the resistance of component 272 between connections 3JQ and 3B.
If the resistance of the air temperature sensor is not:

Check the sealing of the low pressure and high pressure diesel fuel circuits (visual inspections): on the pump
casing, overpressure valve, pipes, rail and injector unions, injector wells, etc., run TEST 1 Low pressure circuit
check and TEST 7 High pressure circuit sealing check.
If all the above checks are correct:
With the vehicle ignition on and the engine stopped for over 1 minute:
Display PR038 Rail pressure, if the value is less than 30 bar, the sensor is correct.
Otherwise, use commands AC005 Cylinder 1 injector, AC006 Cylinder 2 injector, AC007 Cylinder 3 injector,
AC008 Cylinder 4 injector in order to release any residual pressure.
Check that the value of PR038 decreases. If PR038 becomes less than 30 bar, the sensor is correct.
If the fault is still present, replace the rail pressure sensor, component code 1032 (see MR 364 (Mégane II),
