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.
