NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after the clutch pedal is depressed, or during a road test.
Special notes:
Use bornier Ele. 1681 for all operations on the injection computer connectors.
WARNING
This fault may appear if the wiring harness has been damaged.
Follow the procedure described in the Wiring Check in the Introduction.
This check enables the condition and the conformity of the engine wiring harness to be checked.
Check the conformity and adjustment of the clutch switch (position, connection).
– display status ET405 Clutch pedal switch,
– when the clutch pedal is engaged, status ET405 should be INACTIVE,
– when the clutch pedal is disengaged, status ET405 should be ACTIVE,
If these checks are not OK, replace the clutch switch.
If these checks are correct:
Check the connections of the clutch pedal switch.
Check the injection computer connections.
Repair if necessary.
Check for continuity and the absence of interference resistance on the following connection:
Injection computer black 32-track connector A, track C4 Track 1 Clutch pedal switch
Repair if necessary.
Check for earth on track 2 of the clutch pedal switch.
Repair if necessary.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test, then check with the diagnostic tool.

With the ignition on and the camshaft sensor connected:
Use a voltmeter to measure the voltage between tracks 1 and 3 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 with the camshaft sensor
disconnected.
If the voltage is still outside the permitted tolerance values with the sensor disconnected, check the continuity and
absence of interference resistance on the following connection:
Camshaft sensor, track 3 Track 2, PPM1 UPC black connector
If the voltage displayed is correct with the sensor disconnected, replace the camshaft sensor.
If the fault is still present, check the timing adjustment.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test, then check with the diagnostic tool.

NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared stored following a road test or after attempting to start the engine
several times.
Special notes:
Use bornier Ele. 1681 for all operations on the injection computer connectors.
Check the camshaft sensor connections.
Check the injection computer connections.
Check that the camshaft sensor is correctly positioned and mounted.
Also check the general condition, (damaged housing, heating up, etc.)
Carry out the necessary repairs.
Check the camshaft sensor resistance between tracks 2 and 3.
If the resistance is not 10250Ω ± 500 at 20°C, replace the sensor.
Check the continuity and absence of interference resistance of the following connections:
Injection computer brown 48-track connector B, track D1 Track 2 Camshaft sensor.
Injection computer brown 48-track connector B, track A1 Track 1 Camshaft sensor.
With the ignition on and the camshaft sensor connected:
Use a voltmeter to measure the voltage between tracks 1 and 3 of the camshaft sensor:
(This voltage should be equal to the battery voltage ± 0.08 V)
– If the voltage is outside permitted tolerance values, take the measurement again with the camshaft sensor
disconnected,
– If the voltage is still outside the permitted tolerance values with the sensor disconnected, check the continuity
and absence of interference resistance on the following connection:
Camshaft sensor, track 3 Track 2, PPM1 UPC connector
– If the voltage displayed is correct with the sensor disconnected, replace the camshaft sensor.
If the fault is still present, check the timing adjustment.
If the fault is still present, contact the Techline.
