2010 Mercedes Benz C 300 (204.054) V6-3.0L (272.947) Page 1418


Specified values



- Throttle valve not actuated[ca. 1380]ohms



- Throttle valve fully actuated[ca. 480]ohms



M16/6r4 (Actual value potentiometer (sliding contact 2))



- Measure resistance with multimeter between sockets (M.64) 64 and (M.43) 43 of the 126-pole socket box tester.



- Slowly operate throttle flap by hand up to full load.



Specified values



- Throttle valve not actuated[ca. 650]ohms



- Throttle valve fully actuated[ca. 1490]ohms



Question



- Are the measurement values OK?



YES



The measurement values are OK.Further possible causes of fault



- Test voltage supply of the potentiometers of component M16/6 (Throttle valve actuator).



NO



The measurement values are not OK.Possible cause and remedy



- Lines to component M16/6 (Throttle valve actuator)



- M16/6 (Throttle valve actuator)



End of test



4.5. Test voltage supply of the potentiometers of component M16/6 (Throttle valve actuator).



Test prerequisite



- At least one of the relevant actual values is not okay.



- The power supply of component N3/10 (ME-SFI [ME] control unit) is OK.



Test sequence



- Switch off ignition.



- Connect socket box (126-pin) to component N3/10 (ME-SFI [ME] control unit).



- Measure direct voltage with multimeter between sockets (M.39) 39 and (M.43) 43 of the 35-pole socket box tester.



- Switch on ignition.



Specified value



- Voltage[4.75...5.25] V



Question



- Is the measurement value OK?



YES



The measurement value is OK.Possible cause and remedy



- Check lines from component M16/6 (Throttle valve actuator) to component N3/10 (ME-SFI [ME] control unit).



End of test



NO



The measurement value is not OK.Possible cause and remedy



- N3/10 (ME-SFI [ME] control unit)



End of test



2317



This fault can be ignored and erased.



Possible cause:



- This fault can be ignored and erased.
