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
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 and 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, 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.
Electric coolant pump:
The electric coolant pump is activated when the coolant temperature has reached a significant temperature
threshold when the engine has stopped.
The role of the electric water pump is to cool the turbocharger when the engine stops (Vdiag 45, 49 only).
Refrigerant pressure sensor:
The role of the sensor is to measure the refrigerant fluid pressure in the air conditioning circuit.
Electric fuel pump:
The pump is controlled by a relay during each regeneration or purge phase; it is submerged in the tank and is
connected to the secondary fuel circuit only.
Coolant temperature sensor:
The engine coolant temperature sensor informs the computer about the engine coolant temperature.
Air temperature sensor:
The air temperature sensor is fitted in the inlet manifold and informs the computer about the temperature of the air
sucked up by the engine.
Turbocharging pressure sensor solenoid valve:
This solenoid valve operates the turbocharger wastegate pneumatic circuit to lower the turbocharging pressure.
Catalytic converter:
Its role is to convert pollutant gases into harmless gases.
Catalytic converter downstream temperature sensor:
This sensor gives the temperature of the exhaust gas at the catalytic converter output.
Turbine upstream temperature sensor:
This sensor gives the temperature of the exhaust gas at the turbine inlet.
Particle filter downstream temperature sensor:
This sensor gives the exhaust gas temperature at the particle filter outlet (Vdiag 45, 49, 4D only).
Particle filter upstream temperature sensor:
This sensor gives the exhaust gas temperature at the particle filter inlet (Vdiag 45, 49, 4D only).
Particle filter differential pressure sensor:
A differential pressure sensor monitors the status of the particle filter (particle weight) and triggers regeneration.
The role of the sensor is to inform the computer of the pressure difference between particle filter inlet and outlet
(Vdiag 45, 49, 4D only).

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.
