PRESENT
OR
STOREDACCELERATOR PEDAL POSITION SENSOR CIRCUIT1.DEF: Detection of the accelerator pedal depressed at the same time as the brake
pedal.
2.DEF: No signal
3.DEF: Jammed accelerator pedal detected
NOTESPriorities when dealing with a number of faults:
– DF012 Sensor supply voltage no. 2.
Conditions for applying the fault finding procedure to a stored fault:
The fault is declared present when the brake pedal and accelerator pedal are
depressed simultaneously.
Special notes:
– Turbocharging and cruise control are not authorised.
– The engine speed is fixed at 1700 rpm.
–The level 1 warning light is lit for 2.DEF and 3.DEF.
Use bornier Elé.1681 for any operations on the computer connectors.
Use the Wiring Diagram Technical Note, Laguna II ph2, Vel Satis ph2, Espace IV
ph2, Mégane II ph2, Scénic II ph2.
Check that the accelerator pedal is not jammed
Check the condition of the pedal sensor connector (component code 921).
Check the condition of the engine management computer connector (component code 120).
If the connector or connectors 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.
Measure the resistance between connections 3LT and 3LR of component 921.
If the accelerator pedal sensor resistance is not between: 0.7 kΩ < X < 1.7 kΩ or 0.91 kΩ < X < 2.49 kΩ (M9R721),
replace the sensor.

Fault finding – Interpretation of commands13B
VP036INHIBIT FUEL SUPPLY
NOTESThis command enables you to disable the supply to the injectors.
This command is carried out with the engine switched off, and ignition on.
This command allows the injectors to be locked, so that starting is not possible.
Command VP036 allows the engine compressions to be checked in complete safety without disconnecting the
connectors of the injectors or the TDC sensor.
Procedure to follow (cylinder no. 1 is located on the timing end):
– Remove all of the heater plugs, connect the compression gauge with the M9R flexible end piece, part no.
MOT 1772, to a cylinder.
– Position the gear lever in neutral (manual gearbox) or to position P (automatic/sequential gearbox).
– Depress the brake pedal and keep it in this position throughout the test.
– Activate command VP036.
– Attempt to start the vehicle (within 10 seconds of activating command VP036).
If the vehicle does not start, check the cylinder compressions.
Start the procedure again on another cylinder.
WARNING:
Keep the brake pedal depressed for the length of the test.
This command is inhibited automatically after 10 seconds.

Perform the following road test (looking for a loss of power when accelerating under full load):
– in the highest gear ratio, accelerate fully,
– lift your foot off the accelerator pedal completely for at least 2 seconds,
– accelerate fully again,
– release the accelerator pedal completely,
– accelerate slightly.
If the loss of power was not noted during slight acceleration and if there was a loss of engine power during each
acceleration at full load, replace the diesel fuel injector return rail and its overpressure valve (see MR364
(Mégane II ph2), MR370 (Scénic II ph2), MR 395 (Laguna II ph2), 402 (Vel Satis ph2), 405 (Espace IV ph2)
Mechanical, 13B, Diesel injection, Diesel injector fuel return rail: Removal - Refitting).
Check the connection and positioning of the differential pressure sensor (see MR 395 (Laguna II ph2), 402 (Vel
Satis Ph2), 405 (Espace IV ph2), 364 (Mégane II ph2), 370 (Scénic II ph2) Mechanical, 19B, Exhaust, Particle
filter pressure sensor: Removal - Refitting).
Check the conformity of the accelerator pedal position sensor, the brake pedal sensor, the atmospheric pressure
sensor, the exhaust gas recirculation valve, and the damper valve (see Interpretation of statuses and
parameters).
Check the consistency of the signal from the air flowmeter, the engine coolant temperature sensor, the fuel
temperature sensor and the engine speed sensor.
Check the connections, the continuity and the absence of interference resistance of the following components:
– the air flowmeter (apply DF056 Air flow sensor circuit)
– the engine coolant temperature sensor (apply DF001 Coolant temperature sensor circuit)
– the fuel temperature sensor (apply DF098 Fuel temperature sensor circuit)
– the engine speed sensor (apply DF195 Engine speed/camshaft sensor consistency).

ALP5 Irregular engine operation
NOTESBefore analysing this customer complaint, check that there are no faults, and the
conformity (or otherwise) of the parameters and statuses, using the diagnostic tool.
If the customer complaint is not eliminated, perform the following checks.
Use the Wiring Diagram Technical Note, Laguna II ph2, Vel Satis ph2, Espace IV
ph2, Mégane II ph2, Scénic II ph2.
If the engine races during gear changes, if there is a floor mat, check that this is not blocking the accelerator pedal,
the brake pedal and the clutch pedal, then check the conformity of the clutch switch and the conformity of the
accelerator pedal sensor when the pedal is released (see PR086 Pedal potentiometer voltage gang 1 and
PR088 Pedal potentiometer voltage gang 2, Sensor supply).
Measure the resistance between connections 3BG and 3BL of component 149.
If the sensor resistance is not between:
741 Ω < X < 905 Ω at +20°C, replace the sensor.
Check the continuity and absence of interference resistance on the following connections:
•3BG between the components 120 and 149,
•3BL between components 120 and 149.
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.
Check the conformity of the engine earths (oxidation, tightness, etc.).
Check the mounting and condition (overheating) of the sensor.
Check the low pressure circuit: run Test 3 Low pressure circuit check.
Apply the air flow checking procedure, (see conformity in the interpretation of statuses and parameters).
Check the turbocharger: apply Test 7 Variable geometry turbocharger control.
If the fault is still present, test the high pressure fuel circuit:
Run scenario SC035 High pressure fuel circuit fault finding.
To interpret the result, apply the interpretation of command SC035 (see Interpretation of commands).
