Fault finding – Function13B
High pressure pump:
The pump draws in fuel from the tank, which passes through a fuel filter and supplies the fuel injectors.
Rail pressure sensor:
This sensor is fitted to the rail and shows the pressure inside the rail.
Rail pressure regulator:
This component regulates the high pressure of the fuel in the injection system.
Fuel flow regulator:
This component regulates the fuel flow of the injection system.
Fuel temperature sensor:
This sensor measures the temperature of the fuel arising from the pump and injector return.
Piezoelectric injectors:
These injectors enable rapid, precise metering of the quantity of fuel injected, with excellent injection process
repetitiveness.
Vacuum pump:
The vacuum pump is driven by the camshaft. The pump provides the vacuum required to operate the following
components: control solenoid valve, brake servo.
Control solenoid valve:
The solenoid valve connects the vacuum pump and the control diaphragm of the turbocharger blades.
Turbocharger:
The turbocharger is used to supply the engine with more air.
Intake air pressure sensor:
This sensor measures the pressure at the turbocharging air cooler output before the damper valve.
Turbocharger pressure sensor:
This sensor measures the pressure at the turbocharging air cooler output before the damper valve.
Air mass flow meter:
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.
EGR position sensor:
The sensor gives the position of the EGR solenoid valve.
Damper valve (Vdiag 44, 45, 48, 49 and 4D only):
The damper valve is used:
– During regeneration in order to control the flow of fresh air.
– When the engine is switched off, to dampen the engine which helps stop the engine.
– When inoperative, the damper valve is by default in the fully open position.
Particle filter:
The particle filter retains the particles for destruction during regeneration, avoiding propagation of these particles in
the atmosphere (Vdiag 45, 49, 4D only).

Fault finding – Function13B
Cruise control/speed limiter on/off switch:
This switch turns the cruise control/speed limiter on or off.
Water in diesel fuel sensor (optional):
This sensor indicates if water is present in the diesel.
Fan unit relay:
This relay actuates the motor-driven fan assemblies when a temperature threshold has been exceeded.
Accelerator potentiometer:
The accelerator potentiometer informs the computer about the position of the accelerator pedal (engine load).
Brake pedal switch:
The brake pedal switch informs the computer about the pedal status.
Clutch pedal switch:
The clutch pedal switch informs the computer about the pedal status.
Particle filter injector:
The particle filter injector is a low pressure injector. This injector allows the temperature of the second catalytic
converter to be raised to assist with regeneration of the particle filter (Vdiag 45, 49, 4D only).
Only on Kangoo 2: an evaporator plate is present at the particle filter injector outlet, at the level of the bracket
between the exhaust pipe and the catalytic converter.
Heating elements:
The heating elements heat the engine coolant to enhance user comfort (Vdiag 45, 49, 4D only).
Heater plugs:
The heater plugs preheat the combustion chamber so that the explosion of the fuel mixture occurs under the best
conditions to start the engine.

Fault finding – Replacement of components13B
REPLACING THE EGR VALVE (EXHAUST GAS RECIRCULATION VALVE)
After replacing the EGR valve, the computer must store the offset of the new valve (to 0 km), as well as the offset
measured at the time of the last engine cut-off (power-latch). With these data, the computer can detect clogging or
blocking of the EGR valve.
When the valve is replaced, clear the stored offsets so that the program uses the new valve’s offset value. The data
associated with this programming is combined under the EGR programming function.
Procedure to follow after replacement of the EGR valve:
– Select the CLEAR menu.
– Run fault clearing command RZ002 EGR adaptives,
– switch off the ignition,
–wait 30 seconds (auto-supply phase of the computer),
– start the vehicle to allow programming of the EGR valve,
– view parameters PR400 New EGR valve offset and PR129 Last EGR valve offset,
– if the reinitialisation was correctly performed then 0.6 V < PR400 = PR129 < 1.9 V.
REPLACEMENT OF PUMP, INJECTORS, RAIL + RAIL PRESSURE SENSOR OR COMPONENT OF THE LOW
PRESSURE CIRCUIT (DIESEL FILTER etc.).
After replacement of one of these components, carry out clearing using RZ004 Pressure regulation adaptives.
REPLACEMENT OF THE PARTICLE FILTER (Only Vdiag 45, 49, 4D)
After replacement of the particle filter, clear the fault DF308 Clogged particle filter if it is present or stored using
command RZ001 Fault memory. IMPORTANT
It is not possible to try an injection computer coming from the Parts Department because it will no longer be
possible to use it on another vehicle.
