ALP4 Faults occurring while driving
NOTESApply ALP4 after a complete check using the diagnostic tool.
WARNING:
Never drive the vehicle without checking first that there are no throttle
valve faults.
Check that the oil level is not too high.
Check the condition and conformity of the spark plugs.
Check the mounting, cleanliness and condition of the flywheel signal sensor.
Check the flywheel signal sensor air gap.
Check the condition and cleanliness of the flywheel.
Check that the air filter is not clogged.
Check that the air inlet circuit is not blocked.
Check that throttle valve is not clogged.
Check inlet line sealing, from the throttle to the cylinder head.
Check that the fuel vapour absorber bleed is not disconnected or jammed open.
Check that there are no leaks in the fuel vapour absorber bleed system.
Check that there are no leaks in the braking assistance system.
Check that there are no leaks in the oil vapour recovery system (manifold/cylinder head).
Check that there are no leaks around the manifold pressure sensor.
Check that there are no leaks around the air temperature sensor.
Check that the tank vent is not blocked.
Check the conformity of the fuel in the tank, apply test 1 Petrol conformity check.
Check that there are no leaks in the fuel system, from the tank to the injectors.
Check that there are no kinked hoses (especially after a removal operation).
Check the fuel flow rate and pressure.
Check that the injectors are working properly.
Check that the exhaust system is not blocked and the catalytic converter not clogged.
Check the timing setting.
Check the cylinder compressions.

WARNING
During this operation, it is essential to:
–refrain from smoking or bringing incandescent objects close to the work area,
–protect yourself against fuel splashes due to residual pressure in the pipes,
–wear safety goggles with side guards,
–wear leaktight gloves (Nitrile type).
IMPORTANT
–To avoid any corrosion or damage, protect the areas on which fuel is likely to run.
–To prevent impurities from entering the circuit, place protective plugs on all fuel circuit components
exposed to the open air.
Remove 1 l of fuel at the fuel filter outlet, in the engine compartment (see MR 385 (Modus), MR 392 (Clio III),
MR 411 (New Twingo), or MR 442 (E33), Mechanical, 19C, Tank, Fuel tank: Draining), using a pneumatic
transfer pump (part no. 634-200) and place it in 1300 ml plastic cup (part no. 77 11 171 413).
Close the plastic cup with its cover (part no. 77 11 171 416) and let the fuel rest for approximately 2 minutes.
This type of plastic cup is used to prepare paint.
Is the fuel cloudy or does it
separate into two parts?Water is present in the petrol; the fuel is not correct.
Drain the fuel circuit, including the tank (see MR 385 (Modus),
MR 392 (Clio III), MR 411 (New Twingo), or MR 442 (E33),
Mechanical, 19C Tank, Fuel tank: Draining).
Visually compare the fuel removed with the correct petrol.
