Check the status of the connector of the rail pressure sensor (see Wiring Diagram Technical Note, Mégane II
ph2, Scénic II ph2, Component code 1032).
Check the status of the connector of the rail pressure sensor (see Wiring Diagram Technical Note, 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 absence of interference resistance on the following connections:
– Connection code 3LX,
– Connection code 3LY,
– Connection code 3LZ,
between components 120 and 1032.
If any of the connections are faulty and there is a repair method (see Technical Note 6015A, Electrical wiring
repair, Wiring: precautions for repairs), repair the wiring; otherwise replace the wiring.
Check that there is no external diesel leak from the high pressure fuel circuit.
With the ignition on and the engine stopped for over 1 minute:
Display parameter PR038.
– If the pressure is below 90 bar, the sensor is in order.

Sensor electrical conformity
Check the continuity and absence of interference resistance on the following connections:

between components 120 and 1071.
If any of the connections are faulty and there is a repair method (see Technical Note 6015A, Electrical wiring
repair, Wiring: precautions for repairs), repair the wiring; otherwise replace the wiring.
Vehicle with ignition on, and the engine stopped for over 1 minute:
Compare the values of PR041 and PR035 Atmospheric pressure.
If the difference between PR041 and PR035 Atmospheric pressure is greater than 0.1 bar,
check the value of PR035 "Atmospheric pressure" by comparing it with the reading on a vehicle in the workshop
which is correct.
If the value of PR035 Atmospheric pressure is not correct (difference greater than 0.1 bar between the 2
vehicles), contact the Techline.
Otherwise (when the value PR035 Atmospheric pressure is correct), change the turbocharging pressure sensor.
If the difference between PR041 and PR035 Atmospheric pressure is greater than 0.1 bar.
Start the engine, with the engine idling:
Compare the values of PR041 and PR035 Atmospheric pressure.
If the difference between PR041 and PR035 Atmospheric pressure is greater than 0.2 bar.
Check the air inlet circuit:
The low and high pressure air circuit is sealed and not obstructed: the pipes and mounting clamps are present
and tightened, turbocharging pressure sensor, intercooler, etc. are fitted.
Check that the damper valve is not jammed closed.
Repair if necessary.

PR089VEHICLE SPEED
PARAMETER
DEFINITIONGives the vehicle speed in km/h.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
This parameter is transmitted by the ABS computer. This signal is transmitted to the
injection on the multiplex network.
Conformity check with 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)
And then full fault-finding on the ABS computer (see 38C, Anti-lock braking system).

AC004TURBOCHARGING SOLENOID VALVE
NOTESPerform this fault finding procedure:
– following interpretation of an unresolved fault or
– after processing the interpretation of PR041 Turbocharging pressure or
– after a customer complaint (loss of power, smoke etc.).
Ignition on and engine stopped.
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.
1. The following procedure is for checking that the turbocharger and its control circuit are working
properly.
Check the sealing of the high pressure air circuit, run test 3 Low pressure circuit check
Pipe not joined or pierced, pressure sensor disconnected or poorly fitted (seal present), exchanger pierced.
To test the exchanger: stabilise the engine speed between 3500 and 4000 rpm with the vehicle stopped and check
that there are no leaks.
Measure the resistance of the turbocharging pressure solenoid valve between the following connections:
– Connection code 3MG,
– Connection code 3FB,
of component 1475.
Replace the solenoid valve if its resistance is not: 20 Ω ± 2 at +23°C.
Check the continuity, insulation, and the absence of interference resistance on the following connections:
– Connection code 3MG between components 1475 and 120.
– Connection code 3FB between components 1475 and 983.
Run command AC004, if a faint whistling noise is heard along with a clicking from the solenoid valve, go to step
2, otherwise check the operation of the computer output stage:
Vehicle under + after ignition feed, clear the faults displayed by the diagnostic tool.
With the voltmeter in the direct current position:
With the turbocharging solenoid valve connected, connect the voltmeter earth lead to connection 3MG of
component 1475 and the positive lead to connection3FB.
Run command AC004, the voltmeter should display four successive voltages of 2.4 V ± 0.2 V.
If the measurement is not correct, contact the Techline.
