STOREDENGINE SPEED SENSOR CIRCUIT
1.DEF : No signal
2.DEF : Inconsistent signal
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present:
–when an attempt is made to start the engine,
–when the engine is running.
Special notes:
Use bornier Ele. 1681 or Ele. 1590 for all operations on the computer connectors.
The engine speed sensor is consistent with the camshaft sensor.
If the fault is present:
–it is impossible to start the engine or the engine stops,
–the level 2 warning light is lit.
Check the engine speed sensor connections.
Check the injection computer connections.
If one of the connectors is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring
repair, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check that the sensor is correctly mounted and that the flywheel target is not damaged.
Check that the gap between the engine speed sensor and the flywheel is 0.5 to 1.8 mm.
Measure the resistance of the engine speed sensor between terminals A and B of its black connector.
If the winding resistance is not between 510 Ω and 850 Ω at an engine temperature of 20˚C, replace the engine
speed sensor.
Check for continuity and the absence of interference resistance of the following connections:
Injection computer brown 48-track connector B
track B1Track A engine speed sensor
Injection computer brown 48-track connector B
track C1Track B engine speed sensor
If the connection or connections are faulty and there is a repair method (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Repair if necessary.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.

NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after repeated engine starts or with the engine running.
Special notes:
Use bornier Ele. 1681 or Ele. 1590 for all operations on the computer connectors.
If the fault is present:
–the engine will stop immediately,
–it is impossible to restart,
–the level 2 warning light is lit.
Priorities when dealing with a number of faults:
Deal with fault DF013 Sensor supply voltage no. 3 first, if it is present or stored.
CC.0
NOTESNone
Check the rail pressure sensor connectors.
Check the injection computer connections.
Repair if necessary.
Check the continuity and insulation to earth of the following connections:
Injection computer brown 48-track connector B
track G3Track 2 rail pressure sensor
Brown 48-track connector B injection computer
track A4Track 3 rail pressure sensor
Repair if necessary.
If the fault is still present, replace the rail pressure sensor and tighten to 35 ± 5 Nm.
Follow the recommended safety advice (see cleanliness advice).
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.
