1. HAZARDS ASSOCIATED WITH CONTAMINATION
The high pressure direct injection system is highly sensitive to contamination. The risks caused by the introduction of
contamination are:
– damage to or destruction of the high pressure injection system,
– a component seizing up,
– a component losing its sealing.
All After-Sales operations must be performed under very clean conditions. This means that no impurities (particles
a few microns in size) should have penetrated the system during dismantling.
The cleanliness guidelines must be applied from the filter through to the injectors.
What are the sources of contamination?
– metal or plastic swarf,
– paint,
–fibres:
– from cardboard,
– from brushes,
– from paper,
– from clothing,
– from cloths,
– foreign bodies such as hair,
– the ambient atmosphere,
–etc.
2. INSTRUCTIONS TO BE FOLLOWED PRIOR TO ALL OPERATIONS
Check that you have plugs for the unions to be opened (set of plugs available from the Parts Department). The plugs
are single-use only. After use, they must be discarded (once used they are soiled and cleaning is not sufficient to
make them reusable). Unused plugs must be discarded.IMPORTANT
Cleaning the engine using a high pressure washer is prohibited because of the risk of damaging connections.
In addition, moisture may collect in the connectors and create faults in the electrical connections.
IMPORTANT
Before carrying out any work on the high pressure injection system, protect:
– the accessories and timing belts,
– the electrical accessories, (starter, alternator, electric power-assisted steering pump),
– the flywheel surface, to prevent any diesel from running onto the clutch friction plate.

PRESENT
OR
STOREDCAMSHAFT SENSOR SIGNAL
1.DEF: No camshaft signal or timing fault (belt tension or timing adjustment)
2.DEF: Feed fault, signal interference, camshaft sensor internal fault.
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after:
– starting the engine,
– a road test.
Special notes:
Difficulty starting engine.
No effect while driving.
If the fault is present, the level 1 warning light will illuminate.
Use bornier Elé.1681 for any operations on the injection computer connectors.
IMPORTANT
If fault DF119 appears with status 2.DEF and PR055 Engine speed (stored
context) < 150 rpm, there is a diagnostic fault due to the engine stalling: It is not
necessary to interpret this fault.
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.
1.DEF
NOTESNone.
Check the condition of the camshaft sensor connector (see Wiring Diagram Technical Note, Mégane II ph2,
Scénic II ph2, component code 746).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Mégane II ph2, Scénic II ph2, component code 120).
If the connector(s) is/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.

AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition until the end of the power-latch phase, and carry out a road test
followed by a check using the diagnostic tool.

2.DEFNOTESPriorities when dealing with a number of faults:
Deal with fault DF120 Engine speed sensor signal, 1.DEF
first if it is present or stored.
Check the condition of the camshaft sensor connector (see Wiring Diagram Technical Note, Mégane II ph2,
Scénic II ph2, component code 746).
Check the condition of the engine management computer connector (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 sensor mounting and the conformity of the camshaft target.
Check that the camshaft sensor/camshaft sprocket air gap is 3 mm maximum.
Check the continuity of the following connections:
– Connection code 3PL between components 746 and 120.
– Connection code 3CQ between components 746 and 120.
Check for + 12 V after relay on connection 3FB of component 746.
If the connector(s) is/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 tension of the timing belt.
– Check the conformity of the camshaft sprocket/camshaft assembly.
– Check the timing adjustment.
Carry out the necessary repairs.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition until the end of the power-latch phase, and carry out a road test
followed by a check using the diagnostic tool.
