NOTESNone.
Check that the engine speed sensor is correctly fitted and positioned (see MR 364 or 370 Mechanics, 17B,
Petrol injection, engine speed and position sensor).
Check the cleanliness and condition of the engine speed sensor.
Repair if necessary.
Disconnect the battery and the injection computer.
Check the cleanliness and condition of the connections.
Use the "Universal bornier" to check the insulation and continuity of the following connections:
Computer, connector B, track E4 track 2 or B of the engine speed sensor
Computer, connector B, track F3 track 1 or A of the engine speed sensor
Repair if necessary.
Check the resistance of the engine speed sensor between tracks 1 and 2:
Replace the engine speed sensor if the resistance is not between 235 ± 60Ω at 20°C.
If the engine speed sensor has been replaced, the flywheel target has to be reinitialised, then reprogrammed.
Programming reinitialisation:
Use command RZ005: Programming.
Carrying out the flywheel target programming:
– Decelerate a first time with injection cut-off (i.e. feet off the brake, accelerator pedal and clutch pedals) between
3500 and 3000 rpm, in 3rd gear for a manual gearbox and 2nd for automatic gearbox, for at least 5 seconds.
– Decelerate a second time with injection cut-off (i.e. brake, accelerator and clutch pedals released) between
2400and 2000 rpm for K4 engines and between 1800 and
1400 rpm for F4R engines, in 3rd gear for a manual gearbox and 2nd for an automatic gearbox, for at least
5 seconds.
After the operation, check that status ET089 Flywheel target programming is COMPLETED.
(*This is the moment when, during deceleration with no load, the engine drops to idle speed and recovers torque).
AFTER REPAIRFollow the instructions to confirm repair.
Deal with any other faults.
Clear the stored faults.
