Fault finding – Interpretation of parameters13B
PR051EGR VALVE POSITION FEEDBACK
PARAMETER
DEFINITIONThis parameter indicates the opening ratio of the EGR valve in %.
NOTESThere must be no present or stored faults.
Perform this fault finding procedure:
– after finding an inconsistency in the parameter,
– after a customer complaint (loss of power, smoke etc.).
– after interpretation of command AC103 EGR by-pass.
Use the Technical Note Wiring Diagram, Laguna II ph2, Vel Satis ph2, Mégane ll
ph2, Scénic ll ph2, Espace IV ph2.
Conformity check: Engine stopped and ignition on, or engine running, and engine coolant
temperature > 80°C
In the event of a fault, see the interpretation of faults DF209 EGR valve position sensor circuit and DF647 EGR
valve position regulation.
Sensor electrical conformity
Check the continuity and absence of interference resistance of the following connections:
•3JM between components 120 and 1460 or 169,
•3EL between components 120 and 1460 or 169,
•3GC between components 120 and 1460 or 169.
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.
If the fault is still present, contact the Techline.

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: Engine stopped and ignition on, or engine running, and engine coolant
temperature > 80°C
In the event of a fault, test the multiplex network (see 88B, Multiplex).
And then complete fault finding on the ABS computer (see 38C, Anti-lock braking system).

AC012DAMPER VALVE
NOTESCarry out this interpretation:
– after DF645 Damper valve position regulation, DF646 Damper valve position
sensor,
– or after a customer complaint (starting faults, poor performance).
Use the Wiring Diagram Technical Note, Laguna II ph2, Mégane ll, Scénic ll,
Espace IV ph2, Vel Satis ph2.
Measure the resistance between connections 38KQ and 38KP of component 1461.
If the resistance is not between 875 Ω and 1625 Ω replace the damper valve.
Check the continuity and absence of interference resistance of the following connections:
•38KQ between components 120 and 1461,
•38KP between components 120 and 1461.
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.
With the vehicle ignition on, and the engine stopped:
Make sure the damper flap is open,
If not, clean or replace the damper valve.
Actuate the valve using command AC012 and check the damper valve travel and rest position of the valve.
Check the operation of the computer output stage with a voltmeter in the alternating current position:
Actuate the valve with command AC012.
Connect the voltmeter earth lead to connection 38KS of component 1461 and the positive lead to connection
38KQ of component 1461.
The voltmeter should display three cycles of ON-OFF (12.5 V then return to 0V).
If the measurement is correct, replace the damper valve
If the measurement does not show any operation, contact the Techline.
