CALCULATION OF THE THICKNESS OF THE
CYLINDER HEAD GASKET
Check of the protrusion of the pistons
Clean the piston crowns to remove the carbon
deposits.
Turn th e crankshaft one revolution in the direc-
tion of operation to bring piston n° 1 close to Top
Dead Centre.
Fit tool Mot. 252-01 on the piston.
Fit Mot. 251-01 together w ith a dial gauge on
bearing plate Mot. 252-01. With the dial gauge
anvil in contact with the cylind er block, find thepiston Top Dead Centre.
Cleaning
It is very important that the mating surfaces of
the aluminium parts are not scratched.
Use the produ ct Décapjoint to dissolve the part of
the gasket which remains attached .
App ly the prod uct to the section to be cleaned;
wait app roximately ten minu tes, then remove it
using a wooden spatu la.
It is advisable to wear gloves du ring this
operation.
Do not allow any of the prod uct to come into
contact with the p aintwork.
Your attention is drawn to the care which must
be taken w hen carrying out this operation to
prevent the introduction of foreign bodies into
the pressurised oil feed pipes leading to the
camshafts (pipes located both in the cylinder
block and in the cylinder head) and into the oil
return pipe .
CHECKING THE MATING SURFACE
Check whether the mating su rface is deformed
using a r uler and a set of feeler gauges.
Maximu m deformation: 0.05 mm .
Grinding of the cylinder head is prohibited.
Test the cylinder h ead to detect any cracks.

General 13
The use of electronic injection on diesel engines has m ade it possible to optimise the op eration of these en-
gines and thus red uce the emission of pollutan t gases.
The system consists of a compu ter which receives information from:
- the coolant temperature sensor,- the flowm eter (with air temperature sensor),
- the engine speed sensor,
- the vehicle speed sensor,
- the accelerator pedal position sensor,
- the brake switch ,
- the injection start sensor (the sensor is part of the injector of cylind er n° 1),
- the diesel temperature sensor,
- the fuel flow slide valve position sensor,
- the atmospheric pressure sensor (located in the computer).
The comp uter controls:
- the inject ion pump:• fuel flow slide valve,
• advance solenoid valve,
- the cold start system (heater plugs and pre-post heating un it),
- the engine immobiliser system,
- the exhaust gas recirculation system (EGR),
- the injection fault/ pre-heating warning light,
- the fuel shut-off,
- the immersion heaters which heat the cooling circuit coolant (depend ing on vehicle),
- the fan assembly.
SPECIAL FEATURES
The accelerator cable only controls the load p otentiometer located in the engine compartm ent (single track
poten tiometer + no-load sw itch).

DIESEL EQUIPMENT
Location of components 13
The injection p um p provides the compu ter with
information.
To do this, it has two sensors:
- a diesel temperature sensor,- a sensor providing information regarding the
position of the fuel flow slide valve.
Depending on the comm and s received from the
comp uter, the pum p supp lies each cylind er with a
defined quantity of diesel at a d etermined point.
To do this, it has two actuator s:
- an advance solenoid valve; this solenoid valve,
wh ich is controlled by the compu ter, perm its
constant alteration of the adv ance point (pu mp
2-way connector),- an electromagnet which permits alteration of
the p osition of the fuel flow slide valve.
Only the ad vance solenoid v alve and th e diesel
temp erature sensor can be removed. In the event
of failure of one of the other comp onents, send
the pum p to an in jection centre.
The compu ter controls the fuel shu t-off located
on the p um p an d th e engine imm obiliser.

Injection warning light 13
PRINCIPLE OF ILLUMINATION OF THE INJECTION WARNING LIGHT ON THE INSTRUMENT PANEL
The single injection w arning light is u sed for the p re-heating fun ction and for the injection fault function. It
is controlled by the comp uter via track 54 (preheating) or track 26 (fault).
If a fault is present w hen th e ignition is switched on, the ind icator light remains illum inated at the end of the
pre-heating p hase. The coolant temperature w arning light is controlled by the injection comp uter (see sec-
tion 13 "CCTM")
• Failure of a component of the injection system
Faults which result in illum ination of the warning light:
- accelerator pedal position p otentiometer,
- calibrated injector,
- advance solenoid valve (and regulator),
- engine speed sensor,- fuel shut-off,
- computer fau lt ,
- flow slide valve (actuator and potentiometer),
- m ain relay.

AIR CONDITIONING/INJECTION COMPUTER CONNECTION
The electrical connection:
- from the air conditioning compu ter to the injection comp uter is via a wire (track n° 37). In fact, only the
compressor power absorbed information is transmitted along this wire.- from the injection compu ter to the air cond itioning comp uter is via a wire (track n° 28). The compressor
operation authorisation or prohibition information is transmitted along this wire.
AIR CONDITIONING COMPRESSOR OPERATION STRATEGY
During certain p hases of operation, the injection compu ter proh ibits operation of the comp ressor.
Engine starting strategy
Comp ressor operation is pr ohibited for 5 seconds after the engine is started.
Overheating protection strategy
The comp ressor is not engaged if the coolant temperature is above or equ al to: +105 °C.
Strategy for release of pow er on heavy acceleration
The compr essor is cut off on h eavy acceleration if the vehicle speed is below 68 mph (110 km/h), if the engine
speed is below 3600 rpm.
Strategy for release of power at start of movement of vehicle
The comp ressor is cut off wh en the v ehicle starts to move if the vehicle speed is below 15 mph (25 km/h), if 1st
gear or reverse is engaged and if the accelerator p edal position is greater than 35 %. The comp ressor is enga-
ged im med iately on exit from on e of the ranges of use.
Engine stalling prevention strategy
The compressor is cut off if the engine speed is below 625 rpm.

CONDITIONS OF APPLICATION OF THE CHECKS DEFINED IN THIS FAULT FINDING SECTION
In this fault find ing section, each fault is interp reted for a p articular type of storing (fault present, fault
memorised, fault present or memorised).
Therefore, the checks defined for dealing w ith each fault are only to be ap plied to th e vehicle if the fault is
interpreted for the type of fault declared by the diagnostic equipmen t.
If a fault is interp reted in this fault finding section only if it is declared "present", the ap plication of the
fault finding pr ocedu re wh en the fault is only "mem orised" will not enable the reason for the storing of
the fault to be identified. In this case, only a check of the wiring an d connections of the faulty comp onent
should be carried ou t.
If a fault is interpreted wh en it is declared "memorised", the cond itions for confirmation of the current
presence of the fault (and the necessity of app lying the fault finding procedu re) are given in the "NOTES"
box or at the beginning of the interp retation of the fault.
NOTE: The ignition must have been switched off before the diagnostic equipment is switched on.
The characterisation of a m emorised fault is always limited to d EF even if the failure is present but
the conditions un der w hich it is taken into accoun t are not met (it is not possible to obtain a 1.dEF
or a co.0 mem orised).

Clio / Kangoo :
Depend ing on the country, Clio and Kangoo veh icles may or m ay not be fitted with im mersion heaters as
stand ard . They are always fitted with a p ower steering electropu mp assembly if the vehicle is fitted w ith airconditioning.
The comp uter is pre-configured "with immersion heaters" and "without p ower steering" (for "w ithout p o-
wer steering electropum p assem bly"). When a computer is changed on a Clio or Kangoo vehicle, it is necessa-
ry to ensu re that the compu ter is configured correctly and to change this p re-configuration if necessary using
the comman ds "without imm ersion heaters" and "with p ower steering".
The configuration comm and with/ without Air Conditioning cannot be used on th ese vehicles (comp uter
configured "with AC" by default).

If no fault is declared by th e diagnostic equ ipm ent, ensure that the problem is not due to an engine
imm obiliser system fault or a battery charge p roblem.
If the p roblem p ersists:
Check the fuel supp ly circuits (of the p um p an d the injectors) :
- Diesel filter: Abnormal presence of water or smell of petrol.
- Presence of air bubbles in the transparent pipes up stream of the injection pum p before starting (in the
case of a a significant quant ity of bubbles, look for the air leak).
- Cond ition of the d iesel return rail on the injector carriers (if there is a clearance on the clips, change the
rail).
- Look for a diesel leak (pum p inlet click-fit union, pu mp HP outlet, return rail or injector carrier discharge
pipes).
Check the injection p um p setting (recomm end ed value for all F9Q eng ines: 0.32 ± 0.02 mm).
If necessary, carry out a complete check of the engine (starter d rive speed , pump setting, cond ition of the in-
jectors, valve clearances, comp ressions, ...).
If the p roblem only occur s at extremely low t emp eratures, check the op eration of the pre-heating:
Use the "Pre-heating relay"comm and and check that there is a voltage on the h eater p lug leads.If none of the heater p lugs are supp lied, check the connection of the intermediate 2-way connector and the
3-way connector on the r elay un it. Also check the cond ition of the 70 Amp fuse on the engine comp artment

Check the turbocharging pressure:
- Attach a pressure gauge and, during a road test, ensure that the turbocharging pressure is greater
than 0.9 bar.
Refer to the "Turbo" section of the Technical Note if the va lue is not corr ect.
Carry ou t the following checks at the injection p um p:
- Check the flush fitting of the pum p. This is obtained by a vertical line of yellow paint between the
up per and lower sections of the pu mp on the engine side. If there is an offset between the two
sections, change the injection pum p.
- Check the pu mp cover. If there is a trace of an impact, change the injection pum p.
Carry ou t the checks defined in CH ART 6 and check w hether th e air filter is clogged.
Check parameters PR017 "Load p otentiometer p osition" and PR007 "Air flow at in let".
- Check that the value of PR017 changes from 0% at No-load to 100% at Full-load.
- With the engine runn ing, check at idle (850 rpm) that the value of PR007 is between 20 and 50 kg/h.
- Check at full-load d uring a road test at more than 50 mph (80 km/ h) that the value of PR007 is between
360 and 400 Kg/h.
If the value of parameter PR007 "Air flow at inlet" is not correct, check the connections an d the w iring of
the air flow sensor and the conformity of the air circuit (+ presence of foreign bod ies). Change th e air
flow sensor if the value is still incorrect.
By m eans of PR020 "Fuel flow r eference value", check that the comp uter does in fact requ est the
maximum flow of 36 mg/stroke at full-load at an interm ediate engine speed.

PURPOSE OF THE EGR SYSTEM
The exhaust gas recirculation EGR is used to re-
duce the nitrogen oxide (NOx) content of the ex-
haust gas.
PRINCIPLE OF OPERATION OF THE SOLENOID
VALVE
The EGR solenoid valve is controlled by an RCO si-
gnal emitted by the injection compu ter. The RCO
makes it possible to mod ulate the opening of the
solenoid valve and, consequently, the amoun t of
exhaust gas directed back toward s the inlet mani-
fold.
In line with th is signal, the solenoid valve applies
a quantified p art of the vacuu m pu mp vacuu m to
the diaph ragm (C). The diap hragm (C) moves and
pu lls the tie-rod (B) which au thorises passage of
the exhaust gas (by vacuum ) towards the inlet ma-
nifold.
MONITORING THE OPERATION OF THE SYSTEM
DURING A ROAD TEST
To ensure that th e EGR valve control system is
operating correctly, it is possible, by attaching a
pr essure gauge, to check the arrival of the p res-
sure information for the control of the opening of
th e EGR valve. Furth ermore, u sing after sales ser-
vice diagn ostic equip men t (except the XR25, it is
possible to read the param eter: PR 024 EGR so-
lenoid valve RCO.

Create a vacuum of 300 mbars . The p ressureshould not fall by more than 2 mbars per second
(120 mbars per m inute).
Eliminate the vacuum to return the solenoid valve
to atmospheric pressure.
Following th is operation, clear the compu ter me-
mory.
CONDITION OF OPERATION
The computer continuously controls the EGR sole-
noid valve by means of an RCO type signal, except
in the cases described below:
- if the air temperature is greater than 55°C,
- in line with an engine speed / flow / a ir
temperature / coolant temperature / altitude
pattern.
- after having exited the starting phase for 10 se-
conds ,
- if the engine speed is roughly greater than
3250 rpm,
- of the battery voltage is below 10 volts ,
- during the deceleration phase,
- if the engine speed is below 650 rpm,
- in the event of failure:
• of the calibrated injector,
• of the air flow sensor,
• of the advance solenoid valve,
• of the EGR solenoid valve,
• of the EGR regulation.
Special notes
After each entr y into the id le phase, the EGR is
supp lied for 60 seconds and is then interrup ted.
