CONTINUED
Is the engine running on all cylinders?
NO
Check the operation of the injectors: apply test 8 Incorrect injector
operation.
If the fault is still present
Check the conformity of the accelerator pedal position sensor, the brake pedal sensor, the atmospheric pressure
sensor, the exhaust gas recirculation valve and the damper valve.
–Check the consistency of the signal: of the air flowmeter, of the engine coolant temperature sensor, of the fuel
temperature sensor and of the engine speed.
Check the connections, continuity and absence of interference resistance on the air flow sensor (apply DF056 Air
flow sensor circuit, 2.def), the engine coolant temperature sensor (apply DF001 Coolant circuit, 1.def), and the
engine speed (apply DF195 Camshaft sensor/engine speed consistency, 2.def).
Check: – That the diesel filter is not clogged (for the test, see DF053 Rail pressure regulation function
2.def).
–That there are no leaks on the high and low pressure diesel circuits: apply test 3 Turbocharged
air inlet circuit check.
–That the oil vapour rebreathing system is connected.
–The flow regulator (blocked/seized, apply the interpretation for command: AC011 Rail pressure
regulator).
–Check the timing setting (and the position of the high pressure pump sprocket) (see MR 364 (MEGANE II) or
370 (SCENIC II), Mechanical, 11A, Top and front of engine).
–Check the cylinder compressions (balance of the cylinder compressions with the Compression test function
on the CLIP Technic diagnostic tool).
–Measure the engine compressions using the special tool.
If the fault is still present, contact the Techline.YES

NOTESBefore dealing with this customer complaint, check that there are no faults, and
the conformity (or otherwise) of the parameters and statuses using the
diagnostic tool.
If the customer complaint is not ironed out, perform the following checks:
If the engine races during gear changes, check, if there is a floor carpet, that this is not blocking the accelerator
pedal, the brake pedal or the clutch pedal, then check the conformity of the clutch switch and the conformity of the
accelerator pedal sensor when the pedal is released.
Measure the resistance of the engine speed sensor between terminals A and B of its black connector.
If the winding resistance is not between 510 Ω and 850 Ω at an engine temperature of 20˚C, replace the engine
speed sensor.
Check the continuity of the following connections:
–engine management computer, connector B track B1 track A of the engine speed sensor
–engine computer, connector B track C1 track B of the engine speed sensor
Check the conformity of the engine earths (oxidation, tightness, etc.).
Check the mounting, the air gap (check that the engine speed sensor - flywheel gap is 0.5 to 1.8 mm) and the
condition of the sensor (heating).
Replace if necessary.
Check the low pressure circuit.
–Check the pressure regulation solenoid valve by applying section B of the Rough idle fault finding chart.
~ 1600 bar with full load on the accelerator.
–Apply the procedure for checking the air flow; see conformity check.
–Check the turbocharger: apply test 9 Air line at the turbocharger, then test 5 Turbocharger control solenoid
valve check and test 6 Turbocharger.
–Apply the procedure for checking the hydraulic circuit see conformity check.
If the fault is still present:
–Check the balance of the cylinders using the CLIP Technic function, Compression test physical measurements
icon.
–Check the cylinder compressions if necessary using the special tool.
AFTER REPAIRcarry out a road test followed by a complete check with the diagnostic tool.
