M16/6 (Throttle valve actuator) : Position Throttle valve (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 M16/6 (Throttle valve actuator) using actual value.
Test 1.2: Check component M16/6m1 (Actuator motor) by means of actuation.
Test 1.3: Check internal resistance of component M16/6m1 (Actuator motor).
Test 1.4: Perform mechanical inspection of component M16/6 (Throttle valve actuator).
1.1. Check component M16/6 (Throttle valve actuator) using actual value.
Warning!Communication with ECU required.
1.2. 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
1.3. Check internal resistance of component M16/6m1 (Actuator motor).

Warning!
- Connection A of test cable 108 may NOT be connected to connection B of the 126-pin socket box (050).
Continue to test with button F2
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
1.4. Perform mechanical inspection of component M16/6 (Throttle valve actuator).
Test sequence
- Switch off ignition.
- Expose component M16/6 (Throttle valve actuator).
- Slowly operate throttle flap by hand up to full load.
Specified value
- The throttle valve must not stick and must close by internal spring force.
Question
- Is the test o.k?
YES
The test is o.k..Possible cause and remedy
- N3/10 (ME-SFI [ME] control unit)
End of test
NO
The test is not o.k..Possible cause and remedy
- Check intake tract for residue and clean if necessary.If no residue is present, replace component M16/6 (Throttle valve actuator).
