- III 64-126ConnectionTest cable



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 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.



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



- Disconnect coupling M at component N3/10 (ME-SFI [ME] control unit).



M16/6r3 (Actual value potentiometer (sliding contact 1))



- Measure resistance with multimeter between sockets (M.88) 88 and (M.43) 43 of the 126-pole socket box tester.



- Slowly operate throttle flap by hand up to full load.



Specified values



- Throttle valve not actuated[ca. 1380]ohms



- Throttle valve fully actuated[ca. 480]ohms



M16/6r4 (Actual value potentiometer (sliding contact 2))



- Measure resistance with multimeter between sockets (M.64) 64 and (M.43) 43 of the 126-pole socket box tester.



- Slowly operate throttle flap by hand up to full load.



Specified values



- Throttle valve not actuated[ca. 650]ohms



- Throttle valve fully actuated[ca. 1490]ohms



Question



- Are the measurement values OK?



YES



The measurement values are OK.Further possible causes of fault



- Test voltage supply of the potentiometers of component M16/6 (Throttle valve actuator).
