NOTESPriorities when dealing with a number of faults:
If fault DF008 Pedal potentiometer circuit gang 1 is
present at the same time, check that the pedal sensor
connector is connected correctly.
If fault DF004 Turbocharging pressure sensor circuit is
present at the same time, check that the turbocharger
pressure sensor circuit connector is connected correctly.
If fault DF315 Particle filter diff* pressure sensor is
present at the same time,check that the turbocharging
pressure sensor connector is connected correctly.
The following sensors are connected to supply no. 1:
– Turbocharger pressure sensor.
– Particle filter differential pressure sensor.
– Accelerator pedal potentiometer sensor, gang 1.
To locate a faulty sensor and/or connection, disconnect one of these sensors then check whether the fault
becomes stored.
If the fault is still present, start the operation again with the other sensor.
(Wait a few seconds after each disconnection so that the computer can carry out the check). If the fault is stored
after a disconnection, replace the faulty sensor or repair its connection.
Clear the faults created by the multiple disconnections.
If the fault is still present when the sensors have been disconnected:
1. Check the earth insulation of the following connections:
For Laguna II:
– connection code 3LQ between components 120, 1474 and 1290.
– connection code 3LP between components 120 and 1474.
– connection code 3TL between components 120 and 1290.
– connection codes 3LR and 3LS between components 120 and 921.
For Mégane II and Scénic II:
– connection code 3LQ between components 120, 1071 and 1290.
– connection code 3LP between components 120 and 1071.
– connection code 3TL between components 120 and 1290.
– connection codes 3LR and 3LS between components 120 and 921.
If the connection or connections are faulty and there is a repair method (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.
