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:
