Q5 Quattro V6-3.2L (CALB) (2009)
-
Connect multimeter to measure the resistance between terminals - 3 - and - 4 -.
Fuel Level Sensor (G) installed:
‹› Sensor at lower stop: About 285 ohms
‹› Sensor at upper stop: About 60 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 resistance values "tank full" or "tank empty", the fuel delivery unit must be removed and the sensor floater must be placed in upper or
lower end position. Refer to => [ Fuel Delivery Unit ] See: Powertrain Management/Fuel Delivery and Air Induction/Fuel Pump/Service and
Repair/Fuel Delivery Unit.
‹› 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: About 285 ohms
‹› Sensor at upper stop: About 53 ohms
-
Connect multimeter to measure the resistance between contacts - 3 - and - 4 -.
Fuel Level Sensor (G) installed or removed:
‹› Any sensor position: About 340 ohms
