-------------------------------------------------

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锟斤拷, 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).
