CO.0NOTESDealing with a number of faults:
If there is a simultaneous occurrence of fault DF198 Pedal
sensor circuit gang 2, check that the pedal sensor
connector is connected correctly.
Check the condition of the pedal sensor connector (see Wiring Diagram Technical Note, Mégane II ph2,
Scénic II ph2, component code 921).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Mégane II ph2, Scénic II ph2, component code 120).
If the connector(s) is/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 of the pedal sensor between the following connections:
– Connection code 3LR of component 921.
– Connection code 3LT of component 921.
Replace the sensor if the resistance is not 1.2 kΩ ± 0.48 kΩ.
Check the continuity and insulation from earth of the following connections:
– Connection code 3LR between components 921 and 120.
– Connection code 3LS between components 921 and 120.
– Connection code 3LT between components 921 and 120.
