TRANSMISSION OIL TEMPERATURE
PARAMETER
DEFINITIONThis parameter shows the gearbox oil temperature in ˚C.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system operation
programming.
No faults should be present or stored.
Conformity check with engine running, engine coolant temperature > 80 ˚C
With the engine running at idle speed, the gearbox oil temperature varies in accordance with the engine coolant
temperature.
- 40 ˚C > PR004 > 150 ˚C
In the event of a fault, consult the interpretation of fault DF023 Gearbox oil temperature sensor.
Sensor electrical conformity
Disconnect the connector of component 119, measure the resistance of the oil temperature sensor
(on the connector of component 119) between the following connections:
●Connection code 5BZ,
●Connection code 5BY.
The resistance should be between:
- 4.208 ± 0.42 kΩΩ Ω Ω
at 20 ˚C,
- 1.947 ± 0.19 kΩΩ Ω Ω
at 40 ˚C,
- 0.988 ± 0.09 kΩΩ Ω Ω
at 60 ˚C.
In the event of a fault, consult the interpretation of fault DF023 Gearbox oil temperature sensor.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

Note:
Parameter PR006 "Engine speed" applies to the following sub-functions:
"Gear changes".
"Torque activation".
"Driver parameters".
PARAMETER
DEFINITIONThis parameter shows the engine speed in rpm.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system operation
programming.
No faults should be present or stored.
Conformity check with engine stopped and ignition on
PR006 = 0 rpm
In the event of a fault, run a multiplex network test (see 88B, Multiplexing), check the interpretation of the fault
(see 13B EDC16 CP33 M9R 721, Interpretation of faults, DF195 "Camshaft sensor/engine speed
consistency").
Conformity check with engine at idle speed, engine coolant temperature > 80 ˚C
PR006 ≈≈ ≈ ≈
800 rpm
In the event of a fault, check the interpretation of fault (see 13B EDC16 CP33 M9R 721, Interpretation of faults,
