PR743ALCOHOL LEVEL ESTIMATED IN THE TANK
PARAMETER
DEFINITIONThis parameter is used to estimate the percentage of alcohol contained in the petrol in
the main tank.
NOTESThere must be no present or stored faults.
Refer to CLIO III or MODUS Wiring Diagram Technical Note.
Conformity check: Engine stopped and ignition on, or engine running, and engine coolant temperature
> 80˚C.
This percentage must be between:
0 < PR743 < 100%
This parameter allows the computer to estimate the alcohol level contained in the petrol.
Status ET671 Alcohol level programming should be COMPLETED. This indicates that the percentage of alcohol
in the tank has been detected.
If status ET671 Alcohol level programming is NOT COMPLETED, repeat the programming procedure (see
Configurations and programming, Alcohol level programming).
Disconnect the battery and the injection computer.
Check the cleanliness and condition of the connections
Using the universal bornier, check the insulation and continuity on the following connections:
●3GH between components 887 and 120.
●3GK between components 887 and 120.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, replace the upstream oxygen sensor.
If the fault is still present, contact the Techline.

PR926ALCOHOL FUEL ADAPTIVE CORRECTION
PARAMETER
DEFINITIONThis parameter indicates the alcohol adaptive correction.
NOTESThere must be no present or stored faults.
Refer to CLIO III or MODUS Wiring Diagram Technical Note.
Conformity check: Engine stopped and ignition on, or engine running, and engine coolant temperature
> 80˚C.
The correction of the injection duration depends on the estimated alcohol level in the main tank, and the cold
starting procedure for the engine with the Hi-Flex system is carried out accordingly.
Status ET671 Alcohol level programming should be COMPLETED. This indicates that the percentage of alcohol
in the tank has been detected.
This percentage must be between:
0 < PR926 < 100%.
If status ET671 is Not completed, repeat the programming procedure (see Configurations and programming,
Alcohol level programming).
Disconnect the battery and the injection computer.
Check the cleanliness and condition of the connections.
Use the "Universal bornier" to check the insulation and the continuityof the following connections:
●3GH between components 887 and 120.
●3GK between components 887 and 120.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
