CO.0NOTESIn the event of the simultaneous presence of fault DF002 Air
temperature sensor circuit, check that the air flow sensor
connector is connected correctly.
Check the condition of the air flowmeter connector (see Wiring Diagram Technical Note, Laguna II ph2, Vel
Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 799).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Laguna II ph2, Vel Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 120).
If the connector or connectors are 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.
Check the continuity and insulation to earth of the following connections:
•3DV between components 120 and 799,
•3KJ between components 120 and 799,
•3DW between components120 and 799.
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 it.
Check the + 5 V feed to the air flowmeter.
•3KJ of component 799.
Check the +12 V after relay feed to the air flowmeter.
•3FB of component 799.
If the connection or connections are faulty and if there is a repair method (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
Run Test 5 Air flowmeter.
With the flowmeter connected, the vehicle ignition on and engine stopped:
Measure the voltage between connections 3DW and 3DV
of component 799.
Replace the air flowmeter if the voltage is not between 0.3 V < X < 0.7 V.
If the fault is still present, replace the air flowmeter.

•3KJ between components 120 and 799,
•3DW between components 120 and 799.
Check the + 5 V supply of the air flowmeter on the following connection:
•3KJ of component 799.
Check the + 12 V after relay supply of the air flowmeter on the following connection:
•3FB of component 799.
If the connection or connections are faulty and if there is a repair method (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.

If the vehicle has been involved in an accident:
Carry out any necessary repairs,
– clear the fault,
– switch off the ignition,
