temperature
(invalid for
K9K 728)PR059:
Inlet air temperature.
Cold = PR061
Warm: 30°CIndicates the inlet air temperature
in °C. This signal is provided by the
air temperature/pressure sensor.
Default value: 30°C.In the event of a fault,
refer to the
interpretation of
parameter PR059 Inlet
air temperature.
Air circuit
pressure.PR035: Atmospheric
pressure.Indicates the atmospheric pressure
in mbar. The sensor is built into
the computer.If not consistent, check
that PR035 = PR032 =
local atmospheric
pressure, with the
engine stopped and the
ignition on. PR032: Inlet pressure.Indicates the pressure in the inlet
circuit in mbar.

Engine speedPR055: Engine speed.
Cold: 900 rpm.
Warm: 805 rpmIndicates the engine's speed of
rotation in rpm.In the event of a fault,
apply the fault finding

TEST 13 Diesel fuel conformity check
WARNING
– During this operation, it is essential to:
– refrain from smoking or bringing incandescent objects close to the work area,
– guard against petrol splashes caused by the 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.
Preparations:
Weigh an empty 1300 ml plastic cup (part no. 77 11 171 413) with its cover (part no. 77 11 171 416) using
electronic scales such as those used in body paint workshops (for example: PANDA, part no. 77 11 224 995).
Record the weight of the empty plastic cup.
This type of plastic cup is used to prepare paint.
Take a 1 litre fuel sample from the diesel filter outlet (see MR 364 (Mégane II) or 370 (Scénic II), Mechanical,
19C, Tank, Fuel tank: Draining), using a pneumatic transfer pump (part no. 634-200) and place it in the 1300 ml
plastic cup.
Cover the plastic cup with its cover and let it settle for approximately2 minutes.
Is the fuel cloudy or does it
separate into two parts?Presence of water in diesel fuel, the fuel is not compliant.
Drain the fuel circuit, including the tank (see MR 364 (Mégane) or
370 (Scénic), Mechanical, 19C, Tank, Fuel Tank: Draining).
