3. SAFETY INSTRUCTIONS
Safety rules must be observed during any work on a component to prevent any material damage or personal injury:
– Make sure the battery is properly charged to avoid damaging the computers if there is a low charge.
– Use the appropriate tools.
4. REMINDER
To run diagnostics on the vehicle computers, switch on the ignition using the key
To switch off the + after ignition feed, switch off the ignition using the key.

Injection computer:
The injection computer is located in the engine compartment, behind the battery.
TDC sensor:
This sensor is located on the gearbox casing, behind the engine.
Pinking sensor:
This sensor is located between the four injectors.
Refrigerant pressure sensor:
This sensor is located on the air conditioning circuit.
Injection coolant temperature sensor:
This sensor is located on the engine water chamber.
Injection air temperature sensor:
The air temperature sensor is located at the air circuit inlet.
Downstream oxygen sensor:
The downstream oxygen sensor is located on the exhaust pipe downstream of the catalytic converter.
Upstream oxygen sensor:
The upstream oxygen sensor is located on the exhaust pipe after the manifold.
Accelerator potentiometer:
The potentiometer is located on the accelerator pedal.
Brake light switch:
The switch is located on the brake pedal.
Injectors 1, 2, 3, 4:
The injectors are mounted on the engine.
Motorised throttle valve:
The damper valve is located in front of the inlet manifold.
Quadruple ignition coil module (D4D and K7M engines):
The coil module is located in the engine compartment.
Cylinder 1, 2, 3, 4 pencil coils (K4M engine):
They are located on the cylinder head.

Injection computer:
The injection computer receives information from various sensors and sends control signals to various actuators
according to mappings that it has stored in the memory.
TDC sensor:
This sensor allows the computer to provide synchronisation as well as to know the position Top Dead Centre for
injection phasing.
Pinking sensor:
This sensor allows the computer to correct the ignition advance under high engine load to avoid damaging the
engine.
Refrigerant pressure sensor:
The role of the sensor is to measure the refrigerant fluid pressure in the air conditioning circuit.
Injection coolant temperature sensor:
The engine coolant temperature sensor informs the computer about the engine coolant temperature.
Injection air temperature sensor:
The air temperature sensor provides the computer with the temperature of air taken in by the engine.
Oxygen sensors:
The oxygen sensors allow the catalytic converter to correctly perform engine emission control tasks.
Accelerator potentiometer:
The potentiometer allows the computer to take into account driver requests expressed using the accelerator pedal.
Clutch pedal switch:
This switch allows the computer to convert to anti-jerking mode when the clutch pedal is depressed.
Brake light switch:
The brake light switch informs the computer of the brake pedal status.
Two gangs are used if the cruise control function exists.
Injectors:
These injectors enable rapid, precise metering of the quantity of fuel injected, with excellent injection process
repetitiveness.

Motorised throttle valve:
The throttle valve allows engine air flow to be managed according to driver requests.
Quadruple ignition coil module (D4D and K7M engines):
The ignition unit enables ignition (explosion timing control).
Cylinder 1, 2, 3, 4 pencil coils (K4M engine):
The pencil coils enable ignition (explosion timing control).
Fan unit relay:
The engine cooling fan unit relay supplies power to the engine cooling fan.
Camshaft dephaser (F4R engine):
The function of the camshaft dephaser (VVT) is to vary the camshaft adjustment.
The system consists of a dephaser (hydraulic part that modifies the camshaft adjustment) and a solenoid valve.
