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.

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is present after the ignition has been switched on and the brake pedal has
been depressed.
The fault appears after a fault on one of the two brake switch contacts.
See the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/
Symbol 2, Clio II F 6, Kangoo VLL.
With the brake pedal released, check ET039 Brake pedal and ET799 Brake wire contact.
ET039 must be Released and ET799 Inactive.
Check the fitting and mechanical operation of the brake pedal (the pedal returns properly).
If the check is incorrect, check the braking system.
Remove the brake pedal switch, component code 160 (see MR 388 (Logan and Sandero), MR 451 (Duster), MR
423 (Thalia 2/Symbol 2), Mechanical, 37A, Mechanical component controls, Brake pedal switch: Removal
- Refitting or MR 430 (Clio II F 6), MR 374 (Kangoo VLL), Mechanical, 37A, Mechanical component controls,
Brake pedal: Removal - Refitting) and, without depressing the pedal, press sufficiently on the brake pedal switch
to seat it completely in its position.
Lock it by turning it an eighth of a turn.
With the brake pedal depressed, measure the resistance of the brake pedal switch, component code 160 between
connections AP1 (for Logan, Sandero, Duster) or AP10 (for Thalia 2/Symbol 2, Clio II F 6, Kangoo VLL) and
65A. The value must be X > 10 M (between 0°C and 40°C).
If the resistance is not correct, replace the brake pedal switch, component code 160 (see MR 388 (Logan and
Sandero), MR 451 (Duster), MR 423 (Thalia 2/Symbol 2), Mechanical, 37A, Mechanical component controls,
Brake pedal switch: Removal - Refitting or MR 430 (Clio II F 6), MR 374 (Kangoo VLL), Mechanical, 37A,
Mechanical component controls, Brake pedal: Removal - Refitting).
With the brake pedal released, measure the resistance of the brake pedal switch, component code 160 between
connections AP1 (for Logan, Sandero, Duster) or AP10 (for Thalia 2/Symbol 2, Clio II F 6, Kangoo VLL) and
5A, the value must be between 0  < X  1  (between 0°C and 40°C).
If the resistance is not correct, replace the brake pedal switch, component code 160 (see MR 388 (Logan and
Sandero), MR 451 (Duster), MR 423 (Thalia 2/Symbol 2), Mechanical, 37A, Mechanical component controls,

NOTESConditions for application to a stored fault:
The fault is declared present when the engine is idling.
The fault is declared present:
– After depressing the pedal at least 10 times.
See the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/
Symbol 2, Clio II F 6, Kangoo VLL.
With the brake pedal released, check ET039 Brake pedal and ET799 Brake wire contact.
Check that ET039 is Released and ET799 is Inactive.
Check the fitting and mechanical operation of the brake pedal (the pedal returns properly).
If the check is incorrect, check the braking system.
Remove the brake pedal switch, component code 160 (see MR 388 (Logan and Sandero), MR 451 (Duster), MR

to seat it completely in its position.
Lock it by turning it a quarter of a turn anti-clockwise.
The fault should change from present to stored.
While depressing the brake pedal to the end of travel, check ET039 and ET799.
ET039 must be Depressed and ET799 must be Active.
If the statuses are correct, contact the Techline.
