Engine temperature management
The engine is cooled by a 2-speed fan assembly.
To cool the engine, the first speed of the fan assembly is activated if the coolant temperature exceeds 99°C or 94°C
(F4R400/402/403 engines), then the second speed is activated if the temperature exceeds the 102°C or 97°C
(F4R400/402/403 engines). A "very high temperature" warning light illuminates on the instrument panel if the
temperature exceeds 118°C or 113°C (F4R400/402/403 engines).

Programming the alcohol level
– Put the vehicle under + after ignition and wait for the value of parameter PR064 Coolant temperature to be greater
than or equal to 80°C.
– There must be no present or stored faults.
– With the ignition on and engine stopped, note the value of PR743 Estimated alcohol level in the tank.
– Carry out resetting using command RZ064 Programming the alcohol level.
– Start the engine and allow the engine to idle for 5 minutes.
– Check the correct programming using parameter PR743; its value must have changed.
– If programming was not performed correctly, repeat the operation from the start.
– If the fault is still present, contact the Techline.
Injection computer initialisation
Start and stop the engine to initialise the computer and wait for the loss of communication message to appear on the
diagnostic tool. If the message does not appear, wait for 9 minutes.
The computer is automatically configured according to the sensors and options present on the vehicle.
If the data were not saved before the operation, carry out the following operations:
– Programming the VIN code
– Enter the V.I.N. using command VP010 Enter VIN.
– Injector programming
Program the injectors by accessing the sub-section entitled Injector replacement operations.
– Programming the TDC sensor
Program the TDC sensor by accessing the sub-section entitled TDC (Top Dead Centre) sensor replacement
operations.
– Programming the motorised throttle
Program the motorised throttle by accessing the sub-section entitled Throttle valve replacement operations.

– The OBD and Level 1 warning lights illuminate.
See the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/
Symbol 2, Clio II F 6, Kangoo VLL.
Check the connection and condition of the connector of the coolant temperature sensor, component code 244
and of the connections of the injection computer, component code 120.
If the connector(s) are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Disconnect the connector of the injection computer, component code 120 (see MR 388 (Logan and Sandero), MR
451 (Duster), MR 423 (Thalia 2/Symbol 2), MR 430 (Clio II F 6) or MR 374 (Kangoo VLL), Mechanical, 17B,
Petrol injection, Petrol injection computer: Removal - Refitting).
Measure the resistance of component 244 by connections 3JK and 3C of the injection computer connector,
component code 120.
If the resistance of the coolant temperature sensor, component code 244 is not between 100 X 10 k (K7M,
K4M, D4D engines), 85 X 82 k (Duster F4R and K4M engine) at ambient temperature: replace the coolant
temperature sensor, component code 244 (see MR 388 (Logan and Sandero), MR 451 (Duster), MR 423 (Thalia
2/Symbol 2), MR 430 (Clio II F 6) or MR 374 (Kangoo VLL), Mechanical, 19A, Cooling, Coolant temperature

Check the insulation, continuity and absence of interference resistance on the following connections:
–3JK between components 120 and 244.
–3C between components 120 and 244.
If the connection or connections are faulty and if there is a repair method (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
If the fault is still present, contact the Techline.

Deal with the stored fault
Check the resistance of the upstream oxygen sensor, component code 887. The value must be between 7 < X
< 11 or 3 < X < 5 (F4R engine of Duster) and the sensor temperature must be X < 40°C. If the value is not
correct, replace the upstream oxygen sensor (see MR 388 (Logan and Sandero), MR 451 (Duster), MR 423
(Thalia 2/Symbol 2), MR 430 (Clio II F 6) or MR 374 (Kangoo VLL), Mechanical, 17B, Petrol injection, Oxygen
sensors: Removal - Refitting).
Check that the programming of the TDC* sensor is correct. (see Replacement of components section).
Run test SC007 Run OBD test: O2 sensor and start the engine (Only depress the brake pedal to authorise the
starting of the engine).
At the end, check the test results:
STATUS1: Run the test again with the engine coolant temperature X > 90°C.
STATUS2 or STATUS3: Sensor OK.
STATUS4: Replace the upstream oxygen sensor, component code 887 (see MR 388 (Logan and Sandero), MR
