A6 Quattro Sedan V6-3.2L (BKH) (2005)
-
Connect multimeter between terminal - 2 - and - 3 - for resistance measurement.
Fuel Level Sensor G installed:
Sensor at lower stop: approx. 760 to 1003 Ohms
Sensor at upper stop: approx. 70 to 105 Ohms
NOTE:
-
If measured value is 0 Ohms there is a short circuit. If measured value is Infinite Ohms. there is and open circuit in the wiring.
-
To check resistance values "tank full" or "tank empty", the fuel delivery unit must be removed and the floater of the sensor must be placed in
upper or lower end position.
-
With fuel gauge sensor removed, the following values are obtained because of the greater deflection of the floater arm:
Fuel Level Sensor G removed:
-
Sensor at lower stop: approx. 1004 Ohms
-
Sensor at upper stop: approx. 50 Ohms
Assembly is in reverse order of removal, note the following:
-
install rear seat bench.
