M16/6 (Throttle valve actuator) : Output stage (P2101)
Possible cause:
- M16/6 (Throttle valve actuator)
Affected functions:
- Engine diagnosis
- Engine running
-------------------------------------------------
Test 1: Check component M16/6 (Throttle valve actuator).
1. Check component M16/6 (Throttle valve actuator).
Test 1.1: Check component M16/6m1 (Actuator motor) by means of actuation.
Test 1.2: Check internal resistance of component M16/6m1 (Actuator motor).
Test 1.3: Test voltage supply of the potentiometers of component M16/6 (Throttle valve actuator).
1.1. Check component M16/6m1 (Actuator motor) by means of actuation.
Test prerequisite
- Operate engine at idling speed.
Note
- If the throttle valve angle is< 1,1°, unmetered air may be present.
Status of relevant actual value:
- Throttle valve angle:Warning! Communication with ECU required.
Move on to actuation with button F2
1.2. Check internal resistance of component M16/6m1 (Actuator motor).

Test sequence
- Switch off ignition.
- Disconnect coupling M at component N3/10 (ME-SFI [ME] control unit).
- Measure resistance with multimeter between sockets (M.75) 75 and (M.74) 74 of the 126-pole socket box tester.
Specified value
- Resistor[1...10]ohms
Question
- Is the measurement value OK?
YES
The measurement value is OK.End of test
NO
The measurement value is not OK.Possible cause and remedy
- Lines between N3/10 (ME-SFI [ME] control unit) and M16/6m1 (Actuator motor)
- M16/6m1 (Actuator motor)
End of test
1.3. 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
Mercedes Benz Truck G 550 (463.236) V8-5.5L (273.963) Diagnostic Trouble Codes Page 241
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)
