the sensor being present), check the electrical insulation in relation to + 12 V between the following connections:
–3XU between components 120 and 1288,
–3TG between components 120 and 1288.
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.

– starting the engine,
– a road test.
Special notes:
–the level 1 warning light is lit.
Use bornier Elé.1681 for any operations on the injection computer connectors.

Check the condition of the camshaft sensor connector (see Wiring Diagram Technical Note, Laguna II ph2, Vel
Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 746).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Laguna II ph2, Vel Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, 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.
If the fault is stored:
Visually check the condition of the surrounding area.
If, on detection of the fault, the engine speed is considerably lower than the idling speed (less than 150 rpm) and
no customer complaint is declared (warning light indicated by the customer does not come on and vehicle can be
started), the fault was detected because the engine had stalled.
Clear the fault and carry out a road test.

Note:
Measure the resistance between the connections indicated without producing a short circuit between the
connections.
1. Disconnect the sensor before measuring the resistance with an Ohmmeter or multimeter.
2. Resistance between connections 3CQ and 3FB of component 746 (signal and supply) must be between
7.2 kΩ and 13.4 kΩ (10.2 kΩ nominal).
3. The resistance between connections 3PL and 3FB of component 746 (earth and supply) must be greater
than 100 kΩ.
4. The resistance between connections 3PL and 3CQ of component 746 (earth and signal) must be greater than
