STOREDENGINE SPEED SENSOR SIGNAL
1.DEF: Engine speed signal interference, broken tooth on flywheel or
engine speed sensor internal fault
2.DEF: No engine speed signal, or interference affecting the engine speed signal.
NOTESConditions for applying the fault finding procedure to a stored fault:
If the fault is declared present after:
– when an attempt is made to start the engine,
– starting the engine,
– a road test.
Special notes:
The engine speed sensor is consistent with the camshaft sensor.
If the fault is present,
–the level 2 warning light will be lit,
– engine stops or impossible to start,
– engine cut-off,
– turbocharger cut-off,
Use bornier Elé.1681 for any operations on the injection computer connectors.
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.
Check the condition of the engine speed sensor connector (see Wiring Diagram Technical Note, Mégane II ph2,
Scénic II ph2, component code 149).
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.
Check that the sensor is securely attached.
Measure the resistance of the engine speed sensor between the following connections:
– Connection code 3BG of component 149.
– Connection code 3BL of component 149.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
If the winding resistance is not between 200 Ω and 270 Ω at 20°C, replace the engine speed sensor.
