Vehicle under + after ignition feed.
Measure the voltage between
connections 3LU and 3LV of
component 921.Check the continuity and insulation of connections 3LU
and 3LV between components 921 and 120.
If the connection is faulty and there is a repair method
(see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring,
otherwise replace it. Expected result:
4.75 V < X < 5.25 V
Vehicle under + after ignition feed. Fully
depress the accelerator pedal
and measure the voltage between
connections 3LW and 3LV of
component 921.Check the continuity and insulation of connection 3LW
between components 921 and 120.
If the connection is faulty and there is a repair method
(see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring,
otherwise replace it.
If these checks are correct, replace the accelerator pedal
sensor (see MR 392 (Clio III), MR 364 (Mégane II), MR 370
(Scénic II), MR 417 (Kangoo 2), Mechanical, 37A,
Mechanical component controls, Accelerator pedal:
Removal – Refitting) or (see MR 385 (Modus), MR 411
(New Twingo), Mechanical, 37A, Mechanical component
controls, Accelerator brake pedal assembly: Removal –
Refitting). Expected result:
2.16 < X < 2.38 V
Vehicle under + after ignition feed.
Accelerator pedal in no load position,
measure the voltage between
connections 3LW and 3LV of
component 921.Replace the accelerator pedal sensor (see MR 392
(Clio III), MR 364 (Mégane II), MR 370 (Scénic II), MR 417
(Kangoo 2), Mechanical, 37A, Mechanical component
controls, Accelerator pedal: Removal – Refitting) or
(see MR 385 (Modus), MR 411 (New Twingo),
Mechanical, 37A, Mechanical component controls,
Accelerator brake pedal assembly: Removal –
Refitting). Expected result:
0.32 < X < 0.42 V

Does the starter motor operate correctly
(minimum engine speed = 200 rpm)?Carry out the necessary repairs
Is the compression in order? Carry out the necessary repairs
Using the diagnostic tool, check that the injector codes (C2I) are correctly entered on the identification screen.
If not, configure the correct injector codes using command SC002 Enter injector codes.
Is PR038 Rail pressure less than 50 bar under
+ after ignition feed?Apply the fault finding procedure for DF007 Rail
pressure sensor circuit.
Check the low pressure circuit: run TEST 1 Low pressure circuit check.
Check the injectors: run TEST 3 Injector check.
