NOTESConditions for applying the fault finding procedure to a stored fault:
The fault becomes present after an attempt to start.
Special notes:
If the fault is stored, clear the fault from the computer memory.
Switch off the ignition, start the engine and check that the fault does not reappear.
Use bornier Elé.1681 or Elé.1590 for any operation on the injection computer
connectors.
Check the engine speed sensor and camshaft sensor connections.

Repair if necessary.
With the connector disconnected, check the continuity and absence of interference resistance on the
following connections:
– connection code 3FJ,
– connection code 3CQ,
between components 120 and 746.
– connection code 3BG,
– connection code 3BL.

With the ignition on and the camshaft sensor connected:
Use a voltmeter to measure the voltage between connections 3FJ and 3FB or 3FB1 of the camshaft sensor:
The voltage displayed should be equal to the battery voltage ± 0.08 V.
– If the voltage is outside permitted tolerance values, take the measurement again on the connector, with the
camshaft sensor disconnected,
– If the voltage is still outside permitted tolerance values with the sensor disconnected:
Check the continuity and absence of interference resistance on connection 3FB or 3FB1 between
components 746 and 1337 or 983.
If the voltage measured is correct, with the sensor disconnected:
Measure the resistance of the camshaft sensor between connections 3CQ and 3FB or 3FB1.
Replace the sensor if its resistance is not 9750 Ω < X < 10750 Ω at 20°C
Check that the engine speed sensor is correctly mounted and that the flywheel target is not damaged.
Check that the engine speed sensor – flywheel air gap is correct: 0.5 mm < X < 1.8 mm.
Measure the resistance of the engine speed sensor between connections 3BG and 3BL.
Replace the sensor if its resistance is not 510 Ω < X < 850 Ω at 20°C.
