Fault finding – System operation
System outline
The high pressure injection system is designed to deliver a precise quantity of diesel fuel to the engine at a set
moment.
It is fitted with a 112-track BOSCH EDC16 C3 type computer.
The system comprises:
– a priming bulb on the low pressure circuit,
– a diesel filter,
– a high pressure pump with a built-in low pressure pump (transfer pump),
– a high pressure regulator mounted on the pump,
– an injector rail,
– a diesel fuel pressure sensor built into the rail,
– four solenoid injectors,
– a coolant temperature sensor,
– a cylinder reference sensor,
– an engine speed sensor,
– a turbocharger pressure sensor,
– an accelerator pedal potentiometer,
– an EGR solenoid valve,
– an atmospheric pressure sensor integrated into the injection computer,
– an air flowmeter with an air temperature sensor,
– a turbocharging pressure limitation solenoid valve,
– a motorised damper valve,
– a particle filter,
– a particle filter differential pressure sensor,
– a particle filter upstream temperature sensor,
– a particle filter downstream temperature sensor,
– a temperature sensor upstream of the turbine,
– four thermoplungers
The common rail direct high pressure injection system works sequentially (based on the petrol engine multipoint
injection).
This injection system reduces operating noise, reduces the volume of pollutant gases and particles and produces
high engine torque at low engine speeds thanks to a pre-injection procedure.
The high pressure pump generates the high pressure and transmits it to the injector rail. The actuator located on the
pump controls the quantity of diesel fuel supplied, according to the requirement determined by the computer. The rail
supplies each injector through a steel pipe.

STOREDPEDAL POTENTIOMETER CIRCUIT GANG 1
CO.0: Open circuit or short circuit to earth
CC.1 : Short circuit to + 12 V
1.DEF: Inconsistent signal
2.DEF: Accelerator pedal sensor locked
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after a series of full-load/no-load actions on the
accelerator pedal.
Special notes:
Turbocharging, passenger compartment heating resistor activation and the cruise
control/speed limiter are not authorised.
If CO.0, CC.1 or 1.DEF is present the level 1 warning light is lit.
The engine speed is fixed at 1400 rpm if there is a fault on gangs 1 and 2 of the pedal
potentiometer and the engine torque is limited.
Use bornier Elé. 1681 or Elé. 1590 for all operations on the computer connectors.
Priorities when dealing with a number of faults:
Deal with fault first if it is DF011 Sensor feed voltage no. 1 first if it is present or
stored.
WARNING
This fault may appear if the wiring harness has been damaged.
Follow the procedure described in the Wiring Check in the Introduction.
This check enables the condition and the conformity of the engine wiring harness to be checked.
CO.0
NOTESPriorities when dealing with a number of faults:
If fault DF009 Pedal potentiometer circuit gang 2 is
present at the same time, check that the pedal sensor
connector is connected correctly.
Check the pedal potentiometer connections.
Check the injection computer connections.
Repair if necessary.
Check the continuity and insulation to earth of the following connections:
– connection code 3KW,
– connection code 3LR,
between components 120 and 921.
If the connection or connections are faulty and there is a repair method (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Measure the resistance of the pedal potentiometer on gang 1 between connections 3LR and 3LT.
Replace the pedal potentiometer if the resistance is not approximately 0.8 kΩ < X < 2.6 kΩ.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.
