Conditions for application to a stored fault:
The fault is declared present:
–For 1.DEF engine at idle speed.
–For 2.DEF, if impossible to see the fault present, deal with it as stored.
See the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/

With the brake pedal released, check ET039 Brake pedal and ET799 Brake wire contact.
If 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),

NOTESConditions for application to a stored fault:
The fault is present with the engine idling.
Special notes:
After this fault appears:
– The cruise control and speed limiter functions are unavailable.
See the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Clio II F 6.
Without action on the pedal, check that status ET803 Clutch start of travel switch is RELEASED.
If status ET803 is correct, move on to the Part 1 check.
If status ET803 is not correct: remove the clutch pedal position sensor, component code 675 and, without action
on the pedal, press sufficiently on the clutch pedal switch to seat it completely in its position.
Lock it by turning it an eighth of a turn.
Check that the fault has become stored.
If the fault does not change from present to stored, replace the clutch pedal position sensor, component code
675 (see MR 451 (Duster), MR 388 (Logan and Sandero), MR 430 (Clio II F 6), Mechanical, 37A, Mechanical
component controls, Clutch pedal: Removal - Refitting), otherwise move on to Part 1.
Part 1:
With the pedal fully depressed, check that status ET803 is DEPRESSED.
If status ET803 is correct, move on to Part 2.
If status ET803 is not correct: with the clutch pedal depressed, measure the resistance of the switch, component
code 675 between connections 86D and MAM or M.
The value must be between 0 < X 1 .
If the resistance is not correct, replace the clutch pedal position sensor, component code 675 (see MR 451
(Duster), MR 388 (Logan and Sandero), MR 430 (Clio II F 6), Mechanical, 37A, Mechanical component
controls, Clutch pedal: Removal - Refitting).

Check the fitting and sealing of the inlet air pressure sensor, component code 147 (condition of the seals) and look
for possible leaks on the inlet air pipe.
Check the connector of the inlet air pressure sensor, component code 147.
If the connector is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the supply voltage of the sensor on connections 3AJR and 3AJP.

–3AJP between components 120 and 147,
–3AJR between components 120 and 147,
–3AJQ between components 120 and 147.
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.
Replace the inlet air pressure sensor, component code 147 and check that the fault is no longer present (see MR
