Test 5: Test Internal Resistance of Component M16/6 (Throttle Valve Actuator)



Test internal resistance of component M16/6 (throttle valve actuator).

Test prerequisites
- The throttle flap of component M16/6 (throttle valve actuator) should operate freely and must not stick or rub.
- At least one of the relevant actual values is not okay.





Test sequence
- Switch off ignition.
- Detach air connection upstream of component M16/6 (throttle valve actuator).
- Unplug the socket 3 at component N3/10 (ME-SFI control module).

M16/6r3 (Actual value potentiometer (sliding contact 1))
- [N3/10] 3.33<-->3.22 [N3/10]
- Slowly operate throttle flap by hand up to full load.

Specified values
- Idle speed [ca. 828]
- Full load [ca. 1500]

M16/6r4 (Actual value potentiometer (sliding contact 2))
- [N3/10] 3.23<-->3.22 [N3/10]
- Slowly operate throttle flap by hand up to full load.

Specified values
- Idle speed [ca. 1420]
- Full load [ca. 430]

Question: Are the measured values okay?

No
- The measured values are not o.k.
Possible cause and remedy
- Leads to component M16/6 (throttle valve actuator)
- M16/6 (throttle valve actuator

Yes
- The measured values are o.k.
Further possible causes of fault
- Test voltage supply of the potentiometers of component M16/6 (throttle valve actuator).
