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).

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.

NOTESConditions for application to a stored fault:
The fault is declared present after the ignition has been switched on for at least
10 seconds.
If the fault is present:
– the OBD warning light is lit,
– small amount of smoke may be present,
– the atmospheric pressure value changes to safe mode, PR035 Atmospheric
pressure = 900 mbar.
Special notes:
The atmospheric pressure sensor is integrated into the injection computer and
cannot be separated.
Disconnect the injection computer, component code 120, and check the condition of the contacts and the
condition of its connector (see MR 392, 385, 364, 370 and 417, Mechanical, 13B, Diesel injection, Diesel
injection computer: Removal - Refitting).
If the connector is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
If the fault is still present, contact the Techline.
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.
