PARAMETER
DEFINITIONThis parameter indicates the vehicle speed in mph (km/h).
NOTESSpecial notes:
This parameter is transmitted by the ABS computer or by the wheel speed computer.
This signal is transmitted to the injection on the multiplex network.
Conformity check: Engine stopped and ignition on, or engine running and engine coolant
temperature > 80
°C
In the event of a fault, carry out a multiplex network test (see 88B, Multiplexing)
Then a complete fault finding procedure of the ABS computer (see 38C, Antilock braking system) or VSU
(see 38G, Wheel speed computer).

Check the conformity of the diesel filter.
Is the diesel filter in order?Replace the air filter with an original part
(see MR 364 (Mégane II), MR 370

–Switch off the ignition and analyse the diesel fuel in the diesel filter.
–Disconnect the diesel supply and return hoses from the filter.
–Block the filter inlets and outlets straight away with appropriate plugs.
–Remove the filter from its holder and shake it firmly while holding the caps in place. Tap the edge of the filter with
a screwdriver handle to detach any contamination. Empty the contents of the filter into a glass container by lifting
a protective plug, then loosening and completely removing the bleed screw.
Are black particles present on the bottom of the container?
Pass a magnet beneath the container to collect
all the metal particles. Take the magnet away
from the container.Diesel filter in good order.
Do the particles collected using the magnet
cover a surface area greater than 1 cm

Visual inspection of the electrical connector of the solenoid valve
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.
Do the visual inspections show any damage?

Checking the turbocharging pressure regulator to determine if it is a variable geometry turbocharger
Note:
The pressure regulator rod of a variable geometry turbocharger is orthogonal to the turbocharger shaft.
Variable geometry turbochargers are controlled by a solenoid valve.
Depending on the vehicle type, the best visual access will be either from above or from below.
Note:
If necessary, according to the vehicle type and the accessibility of the pressure regulator, connect the vacuum
pump to the end of the pressure regulator pipe at the solenoid valve outlet.
Using a manual vacuum pump, apply a vacuum on the turbocharging pressure regulator of approximately
650 mbar.
1. Check that the fitting is completely leaktight.
2. Check that the control rod is resting against its stop.
3. Lock the vacuum device and check that the pressure variation is not greater than 100 mbar in 10 seconds.
4. Release the pressure and check that the control rod comes back to its initial position without jerking.
Repeat the complete sequence 3 times.
Is the pressure regulator leaktight and is the rod movement correct?
The turbocharger is correct.
End of procedure.Replace the turbocharger (see MR 364 (Mégane II), 370
(Scénic II), 392 (Clio III), 385 (Modus), 411 (New Twingo)

Checking the turbocharging pressure regulator to determine if it is a fixed geometry turbocharger
Note:
The pressure regulator rod of a fixed geometry turbocharger is aligned with the turbocharger shaft.
Fixed geometry turbochargers are controlled by a solenoid valve.
Depending on the vehicle type, the best visual access will be either from above or from below.
Note:
If necessary, according to the vehicle type and the accessibility of the pressure regulator, connect the vacuum
pump to the end of the pressure regulator pipe at the solenoid valve outlet.
Using a manual vacuum pump, apply a vacuum on the turbocharging pressure regulator of approximately
650 mbar.
1. Check that the fitting is completely leaktight.
2. Check that the control rod moved several millimetres.
3. Lock the vacuum device and check that the pressure variation is not greater than 100 mbar in 10 seconds.
4. Release the pressure and check that the control rod comes back to its initial position without jerking.
Repeat the complete sequence 3 times.
Is the pressure regulator leaktight and is the rod movement correct?
The turbocharger is correct.
End of procedure.Replace the turbocharger (see MR 364 (Mégane II), 370
