lost with computer: EDC16 C36, check the tool connection and computer power supply before switching
the ignition back on.
Start the engine and re-establish dialogue.
This fault may be linked to a write error following disconnection of the battery when the computer was in the
process of writing to the EEPROM phase (computer memory).
If this is the case, loading a new calibration will remove the fault.
If a more recent calibration is available, load this calibration on to the computer.
If the fault is still present:
– use the command RZ034 Computer memory,
– Switch off the ignition and wait for the computer dialogue lost message,
– switch on the ignition again,
– define the injector codes using the control SC002 Enter injector codes.

WARNING
If the fault is stored:
Visually check the condition of the surrounding area.
If, on detection of the fault, the engine speed is considerably slower than the idling speed (less than 400 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 stalled. Clear the fault and carry out a road test.
Check the sensor mounting and the conformity of the camshaft target.
Check that the camshaft sensor/camshaft sprocket air gap is 3 mm maximum.
Check the electrical specifications of the sensor:
Note:
Make sure that the resistance is measured between the tracks indicated.
1. Disconnect the sensor before measuring the resistance with an Ohmmeter or multimeter.
2. The resistance between connections 3FB and 3PL of component 746 (earth and supply) must be between
7.2 kΩ and 13.4 kΩ (10.2 kΩ nominal).
3. The resistance between connections3FB and 3CQ of component 746 (output and feed) should be above
100 kΩ.
4. The resistance between connections3PL and 3CQ of component 746 (output and earth) should be above
100 kΩ.
If the values are incorrect, replace the camshaft sensor.
Check the continuity of the following connections:
– Connection code 3PL between components 746 and 120.
– Connection code 3CQ between components 746 and 120.
Check for + 12 V after relay on connection 3FB of component 746.
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 still present, replace the camshaft sensor.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition until the end of the power-latch phase, and carry out a road test
followed by a check using the diagnostic tool.
