I. HAZARDS ASSOCIATED WITH CONTAMINATION
The high pressure direct injection system is highly sensitive to contamination. The risks associated with
contamination are:
–damage to or destruction of the high pressure injection system,
–components jamming,
–components losing seal integrity.
All After-Sales operations must be performed under very clean conditions. This means that no impurities
(particles a few microns in size) should have entered the system during dismantling.
The cleanliness principle must be applied from the filter 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,
–ambient air
–etc.
II. ADVICE TO BE FOLLOWED BEFORE ANY OPERATION
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 also be discarded.
Check that you have hermetically resealable plastic bags for storing removed parts. Parts stored in this way will be
less susceptible to the risk of contamination. The bags are single-use only. Once used, they must be thrown out.
Use lint-free cleaning cloths (cloth part reference 77 11 211 707). Using normal cloth or paper is prohibited. They are
not lint-free and could contaminate the fuel circuit. Each cloth should only be used once.
Use fresh cleaning agent for each operation (used cleaning agent is contaminated). Pour it into an uncontaminated
container.
For each operation, use a clean brush in good condition (the brush must not shed its bristles).
Use a brush and cleaning agent to clean the unions to be opened.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 electrical connection faults.
IMPORTANT
Before any work is carried out 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.

Cruise control - speed limiter (CC / SL) management
When activated, the cruise control function maintains the vehicle at a preselected speed, regardless of the
driving conditions encountered. Using the control buttons, the driver can increase or reduce the speed of the vehicle.
The cruise control function can be deactivated either using the control buttons, or by switching off the cruise control
function selector switch or when system events are detected such as the brake or clutch pedal being depressed,
or when system errors are detected such as an inconsistent vehicle speed or excessive vehicle deceleration.
The cruise control function can also be temporarily overridden when the driver wants to resume control of
the vehicle and exceed the selected cruising speed by pressing the accelerator pedal, which causes the controlled
fuel flow to be exceeded. The cruising speed is resumed when the driver releases the accelerator pedal.
It is possible to reactivate cruise control and to return to the last cruising speed after the function has been
deactivated for whatever reason, during the same cycle of use (computer supply voltage not cut off). The vehicle will
then attempt to return to the cruising speed using a controlled vehicle acceleration rate.
When activated (using the selection switch), the vehicle speed limiter function limits the vehicle speed to
a preselected value.
The driver controls the vehicle in the normal way using the accelerator pedal until the limit speed is reached. If an
attempt is made to exceed this speed, the system will ignore the pedal request and will limit the vehicle speed,
provided that the driver continues to depress the accelerator pedal.
As with the cruise control function, the limit speed can be altered using the control buttons by pressing briefly or by
pressing and holding (pressing and holding not active on Kangoo 2).
For safety reasons, the limit speed can be exceeded by depressing the accelerator pedal beyond the pedal position
limit value. The vehicle speed will then be totally controlled by the pedal until the speed falls back below the cruising
speed when the speed limiter function will once again be reactivated.
The driver has the following controls for the cruise control - speed limiter function:
–accelerator pedal,
–brake pedal,
–clutch pedal (not for sequential gearbox),
–function selector switch, used to select cruise control or speed limiter operating mode,
–activation switch on the steering wheel,
–required speed adjustment switch on the steering wheel.

High and low pressure pump:
The pump draws in fuel from the tank, which passes through a fuel filter and supplies the fuel injectors.
Injector rail:
The injector rail receives and redistributes fuel under high pressure to the injectors.
Solenoid injectors:
These injectors enable rapid, precise metering of the quantity of fuel injected, with excellent injection process
repetitiveness.
Catalytic converter:
Its role is to convert pollutant gases into harmless gases.
Heater plugs:
The heater plugs create a hot point in the combustion chamber to improve starting in low temperature conditions.
They are also used to improve idle speed stability under some conditions.
Turbocharger:
The turbocharger is used to supply the engine with more air.
Turbocharger control solenoid valve (K9K 724, 766, 802, and 812 only):
This solenoid valve controls the turbocharger wastegate.
Air flowmeter (if present on the vehicle):
The flowmeter measures the amount of fresh air which goes back into the engine.
EGR valve:
The exhaust gas recirculation enables nitrogen oxide (NOx) emissions to be reduced significantly.
Cruise control - speed limiter on - off switch:
This switch turns the cruise control/speed limiter on or off.
Accelerator pedal potentiometer:
The accelerator potentiometer informs the computer about the position of the accelerator pedal (engine load).
Clutch pedal switch:
The clutch pedal switch informs the computer about the pedal status.
TDC sensor:
The angular position is measured using a magneto-inductive sensor triggered by machined teeth on the flywheel.
This sensor gives the engine speed as well as the position of the crankshaft for injection.
Camshaft sensor:
This sensor gives a signal to perform the injection cycle.
When the piston of cylinder 1 is at top dead centre (TDC), it can be either at the end of the compression stroke
or at the end of the exhaust stroke. The camshaft sensor enables a distinction to be made between these two states.
Refrigerant pressure sensor:
Its role is to measure the refrigerant pressure in the air conditioning circuit.
Engine coolant temperature sensor:
The engine coolant temperature sensor informs the computer about the engine coolant temperature.
Water in diesel fuel sensor (New Twingo and Kangoo 2 only):
This sensor determines if there is water present in the diesel fuel.

the fresh air flow if the flow sensor is not fitted to the vehicle.
Atmospheric pressure sensor:
This sensor allows the atmospheric pressure to be supplied to the computer.
Inlet manifold pressure sensor:
This sensor indicates the pressure in the inlet circuit.
Rail pressure sensor:
This sensor is fitted to the rail and shows the pressure inside the rail.
Fuel temperature sensor:
This sensor measures the fuel return temperature from the pump and injector return.
Accelerometer:
This sensor measures vibrations and allows injector deviation compensation terms to be calculated.
Passenger compartment heating resistor relay:
This relay allows the passenger compartment heating resistors to be controlled during their activation.
Air conditioning compressor relays:
This relay allows the air conditioning compressor clutch to be controlled during its activation.
Fan unit relay:
This relay actuates the motor-driven fan assemblies when a temperature threshold has been exceeded.
