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



2.5. 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



1352



The measured air mass is implausible compared to the position of the throttle valve. (P0101)



Possible cause:



- B2/5 (Hot film mass air flow sensor)



- M16/6 (Throttle valve actuator)



Affected functions:



- Engine diagnosis



- Engine output



-------------------------------------------------



Test 1: Check component B2/5 (Hot film mass air flow sensor).



Test 2: Check component M16/6 (Throttle valve actuator).



1. Check component B2/5 (Hot film mass air flow sensor).



Test 1.1: Check signal of component B2/5 (Hot film mass air flow sensor) via actual value with engine OFF.



Test 1.2: Check signal of component B2/5 (Hot film mass air flow sensor) via actual value with engine speed greater than 3500 rpm.
