Sensor electrical conformity
Test the air inlet circuit (from the air filter inlet to the inlet manifold tracts, run test 5 Inlet circuit check):
–air filter unit inlet not blocked and filter not clogged,
–oil vapour recirculation circuit connected correctly,
–low and high pressure air circuit sealed and not obstructed: ducts, mounting clamps present and tightened,
turbocharging pressure sensor fitted, exchanger, etc., run TEST 1 Low pressure circuit check and TEST 7
High pressure circuit sealing check
–check that the damper valve is not jammed closed.
Carry out the necessary repairs.
Check the electrical conformity of the air flowmeter:
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 (or 3FB3) of component 799.
Check the continuity and absence of interference resistance of the following connections:
–3DV,
–3DW, between components 120 and 799.
Flowmeter connected, vehicle ignition on and engine stopped:
Measure the voltage between connections 3DW and 3DV of component 799.
If the voltage is not between 0.3 V and 0.7 V, replace the air flowmeter, component code 799 (see MR 364 (Mégane

PARAMETER
DEFINITIONThis parameter indicates the air temperature of the flowmeter in °C.
NOTESSpecial notes:
Depending on the engine type, the air temperature is given by the air flowmeter or the
exterior air temperature sensor.
Conformity check: Engine stopped and ignition on, or engine running and engine coolant
temperature > 80
°C
Check the condition of the air flow sensor connections.
If the connector is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
If necessary, replace the sensor (see MR 364 (Mégane II), MR 370 (Scénic II), MR 385 (Modus), MR 392 (Clio III),
MR 411 (New Twingo), MR 417 (Kangoo 2), Mechanical, 12A, Fuel mixture, Air flowmeter: Removal -
