NOTESConditions for applying the fault finding procedure to a stored fault:
If the fault is declared present after:
– a road test followed by a power latch phase.
Special notes:
The level 1 and EOBD (European On Board Diagnostic) warning lights are lit.
If the fault is stored, clear the fault from the computer memory.
In the main screen of the CLIP diagnostic tool, note the injector codes.
Clear the computer memory using command RZ034 Computer memory.
Switch off the ignition, wait for the diagnostic tool message (maximum wait 8 min): Loss of dialogue with the
computer: EDC16 CP33, check the tool connection and the computer supply voltage then switch on the
ignition again.
Switch on the ignition and re-establish dialogue.
If the fault is still present, contact the Techline.
If the fault is no longer present, carry out the programming (see Programming).
Switch off the ignition, wait for the diagnostic tool message (maximum wait 8 min): Loss of dialogue with the
computer: EDC16 CP33, check the tool connection and the computer supply voltage then switch on the
ignition again.
For vehicles equipped with a particle filter:
– Check the exhaust pipe for leaks or blockage. Repair if necessary.
– Carry out a particle filter regeneration using command SC017 Particle filter regeneration (see Interpretation
of commands) and perform an oil change if the vehicle is not new.

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.

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
100 kΩ.
If the values are incorrect, replace the camshaft sensor.
Check the continuity of the following connections:
•3PL between components 120 and 746,
•3CQ between components 120 and 746.
Check the + 12 V after relay feed to the camshaft sensor on the following connection:
