PR225AIR FLOW SENSOR VOLTAGE
PARAMETER
DEFINITIONThis parameter indicates the air flow sensor voltage in volts.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
There must be no faults present.
Perform this fault finding procedure:
– after finding an inconsistency in the parameter,
– or after a customer complaint (lack of power, smoke etc.).
Conformity check: Engine stopped and ignition on, or engine running, and engine coolant
temperature > 80°C
The air flow sensor voltage value must be between:
0 V < PR225 < 5 V.
In the event of a fault, consult the interpretation of parameter DF056 Air flow sensor circuit.

SC001WRITE SAVED DATA
NOTESTo use this command, first save the data with the SC003 Save computer data
command.
The writing is carried out after the computer has been reprogrammed or replaced.
Engine stopped.
In the diagnostic tool, select scenario SC001.
Note:
If no files have been saved before, a write error appears when command SC001 is activated.
Validating this command writes the data saved using command SC003 Save computer data.
The data is as follows:
– vehicle-specific idling,
– injector codes,
– various offsets for components, EGR, damper valve,
– options available on the vehicle and generated by the computer.
This data will configure the computer and will prevent:
– engine malfunction after reprogramming or replacing the computer,
– incorrect interpretation of the information provided by the diagnostic tool.

SC002ENTER INJECTOR CODES
NOTESThis command is carried out after the replacement of one or more injectors.
Engine stopped.
To enter this information, select command SC002 in the diagnostic tool.
Procedure to be followed:
– Read the 7-character alphanumeric codes engraved on the upper section of the injector bodies. The IMA*
codes should be read from left to right (see illustration in MR 402 (Vel Satis ph2), MR 395 (Laguna II ph2),
MR 364 (Mégane II ph2), MR 370 (Scénic II ph2), MR 405 (Espace IV ph2) Mechanical, 13B, Diesel
injection, Diesel injector, Removal – Refitting)
Note: When entering characters, confusion can arise between:
– Figure 1 with the letters I and L,
– Figure 2 with the letter Z,
– Figure 5 with the letter S,
– Figure 6 with the letter G,
– Figure 8 with the letter B.
After programming or reprogramming the computer, it is essential to enter the 4 injector codes before confirming
the entry.
– Enter each injector code for the associated cylinder.
–Important: cylinder no. 1 is located at the timing end.
– Confirm the change of injector code configuration.
– When the command is completed, the modified codes appear in the current column.
– Check that the codes correspond to those read earlier.
If the codes entered appear in neither the "current" column nor the "desired" column, check the codes read and
make sure the data has been entered correctly.
– Exit fault finding mode.
– Switch off the ignition and wait for the diagnostic tool message (maximum wait 8 min): Loss of dialogue with
the computer: EDC16 CP33, check the tool connection and the computer supply.
– Switch the ignition back on and check for faults.
–DF066 Injector code(s) should be stored.
