CURRENT TURBINE SPEED
NOTESThere must be no present or stored faults.
Check the cleanliness and condition of the turbine speed sensor and its connections.
Check the insulation, continuity and the absence of interference resistance to earth, to + 12 V and the
following connections:
●connection code 5DA, between components 119 and 1017,
●connection code 5DB, between components 119 and 1017.
If any of the connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring
repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check the turbine speed on the diagnostic tool:
Gear lever position at N or P.
Oil temperature 43 ˚C: turbine speed ~ 681 rpm and engine speed: ~ 743 rpm.
Oil temperature 45 ˚C: turbine speed ~ 654 rpm and engine speed: ~ 743 rpm.
AFTER REPAIRRepeat the conformity check from the start.

ENGINE/TURBINE SPEED DIFFERENCE
NOTESThere must be no present or stored faults.
Check the cleanliness and condition of the engine speed sensor and its connections.
Run a multiplex network test (see 88B, Multiplex).
After these checks, if parameter PR006 Engine speed is absent, refer to the interpretation of the parameter
(see 17B, Petrol injection or 13B, Diesel injection).
Check the cleanliness and condition of the turbine speed sensor and its connections.
This parameter is the difference between parameter PR006 Engine speed and parameter PR007 Turbine speed.
Check the engine/turbine speed difference with the diagnostic tool:
Engine idling:
Engine speed: ~ 743 rpm and turbine speed: ~ 654 rpmdifference = ~ 89 rpm.
AFTER REPAIRRepeat the conformity check from the start.
