The upstream oxygen sensor is located on the exhaust pipe after the manifold.

Accelerator potentiometer:

The potentiometer is located on the accelerator pedal.

Clutch pedal switch:

The switch is located on the clutch pedal.

Brake light switch:

The switch is located on the brake pedal.

Oil pressure sensor:

The oil pressure sensor is located under the exhaust manifold to the left of the engine compartment.

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.

Cylinder 1, 2, 3, 4 pencil coils (for K4M 768 / 830 / 831 / 834):

They are located on the cylinder head.

Quadruple ignition coil module (for K7M 750):

The coil module is located in the engine compartment.

Cruise control/speed limiter control:

Role of components

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.

Fuel vapour recirculation solenoid valve:

This solenoid valve allows petrol vapour to be recirculated.

Injection coolant temperature sensor:

The engine coolant temperature sensor provides the computer with 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.

Oil pressure sensor:

The oil pressure sensor allows the computer to be informed of engine oil pressure values.

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.

Cylinder 1, 2, 3, 4 pencil coils (for K4M 768 / 830 / 831 / 834):

The pencil coils enable ignition (explosion timing control).

Quadruple ignition coil module (for K7M 750):

The ignition unit enables ignition (explosion timing control).

Steering column control:

The steering wheel controls allow the driver to operate the cruise control/speed limiter functions.

Cruise control switch:

The cruise control switch allows the cruise control/speed limiter functions to be activated or deactivated.

Fan unit relay:

The engine cooling fan unit relay supplies power to the engine cooling fan.

Additional fuel tank solenoid valve (Flex Fuel engines only):

The purpose of this solenoid valve is to inject "traditional" petrol from the additional tank (1 L) in order to avoid the

problem of poor cold starting.

Additional fuel pump relay (Flex Fuel engines only):

The relay supplies power to the additional fuel pump.
