PARAMETER
DEFINITIONThis parameter indicates the engine coolant temperature in °C.
NOTESSpecial note:
Default value: 80 °C.
Conformity check: Engine stopped and ignition on, or engine running and engine coolant

PR132AIR FLOW
PARAMETER
DEFINITIONThis parameter indicates the inlet air flow in mg/st.
NOTESSpecial notes:
For vehicles that are not equipped with a flowmeter, the air flow is estimated using
the following parameters:
–Inlet air temperature,
–The atmospheric pressure,
–The EGR valve position,
–The fuel flow,
–The engine speed.
There must be no faults present.
Perform this fault finding procedure:
–after finding an inconsistency in the parameter,
–or after a customer complaint (lack of power, smoke etc.).
See the Wiring diagrams Technical Note for the vehicle.
Conformity check with engine stopped and ignition on.
Indicates the inlet air flow PR132 ≈ 0 mg/st.
Conformity check: Engine running at idle speed and engine coolant temperature > 80
°C
Indicates the inlet air flow PR132 ≈ 200 mg/st.

PR730AIR FLOW SENSOR TEMPERATURE
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 -

Measure the resistance between the following connections:
(vehicle with flowmeter)
–3B and 3DW of component 799;
(vehicle without flowmeter)
–3PB and 3KQ of component 272,
–3SH and 3KQ of component 272,
–3JQ and 3KQ of component 272.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical

Switch off the engine.
Note:
The requested checks are only visual.
1. Check that the connector is correctly connected and locked.
2. Check the absence of damage to the electric wires where they leave the insulation.
Disconnect the connector to continue the checks.
3. Check the absence of thermal damage to the unit and mechanical damage to the lock.
4. Check the absence of deformations of the contacts (clips and tabs).
5. Check the sealing of the connector.
