Q7 Quattro V6-3.6L (BHK) (2007)
‹› Ignore - 2 -.
-
Connect multi meter between terminal - 2 - and - 3 - for resistance measurement.
Fuel level sensor 2 (G169) installed:
‹› Sensor at lower stop: 760 to 842 ohms.
‹› Sensor at upper stop: 67 to 86 ohms.
‹› 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 "tank full" or "tank empty" resistance values, the fuel level sensor 2 (G169) must be removed => [ Fuel Level Sensor 2 ] See: Service
and Repair/Fuel Level Sensor 2, and the sensor floater must be placed in upper or lower end position.
‹› With fuel level sensor 2 (G169) removed, the following values are obtained because of the greater deflection of the floater arm:
Fuel level sensor 2 (G169) removed:
‹› Sensor at lower stop: approximately 990 ohms.
‹› Sensor at upper stop: approximately 51 ohms.
Assembly is in reverse order of removal, note the following:
-
Install locking flange cover.
-
Install tank access carpet frame in floor covering.
