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.

After-Sales regeneration comprises 4 important stages:
– Heating of the engine and checking for a small quantity of soot in the particle filter by measuring the differential
pressure.
– The system changes from combustion mode and starts to regenerate the particle filter. Gradual cooling of the
particle filter.
– End of After-Sales regeneration.
Stopping conditions:
– Dialogue with the diagnostic tool has been lost.
– Vehicle movement detected by speed sensor.
– Brake or clutch pedal depressed.
– Stop regeneration requested by the diagnostic tool.
– End of test.
The procedure lasts 30 minutes.
– At the end of regeneration, a message announces whether the regeneration has been successful or which
operations to carry out.
CONFIRMING THE REGENERATION PROCESS:
At the end of regeneration, a message appears to announce whether the regeneration was successful:
particle filter regeneration successful: regeneration completed correctly.
weight of soot too high - run command SC017 again: regeneration failed because the weight of soot at
the end of regeneration was too high and the temperature upstream of the particle filter was too low. Check
the oil level before starting another regeneration.
weight of soot too high: regeneration failed because the weight of soot at the end of regeneration was
too high in spite of the correct temperature upstream of the particle filter. The particle filter is full of residue
(regeneration impossible), refer to the fault finding chart ALP21 Particle filter warning light lit.
present or stored fault: regeneration failed because faults were declared.
Refer to the interpretation of faults, after resolving the faults, run command SC017 again.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool
.
