TT Quattro Roadster L4-1.8L Turbo (AMU) (2002)
Test Step 3.3 - 3.4
Test step 4 - A/C flap position sensors (in flap motors) (-V68-/-G92-, -V70-/G112-, -V71-/-G113-, -V85-/-G114-)
Test Step 4.1 - 4.2
NOTE:
-
The resistance of the potentiometers in the positioning motors can only be measured at the motors themselves (they are connected in parallel)
(specification: 3.6 kOhm to 5.7 kOhm , between terminals 1 and 3).
-
The resistance of the potentiometers in the flap motors (between terminals 1 and 2 and between terminals 3 and2) depends on the position of the
motor, and must always be measured with the motor installed. The maximum specified value will not be obtained in test steps 4.1 and 4.2. To
obtain the maximum specified value, all the connectors on the other flap motors would have to be disconnected; (motors are connected in parallel).
-
If the A/C control head -E87- detects the malfunction "Potentiometer short circuit to Ground" or "Open/short circuit to B+," test all the
