Component Testing
- Ignition OFF, remove the A7 Fuel Pump and Level Sender Assembly.
- Sweep the fuel Level Sensor through its full range of motion while measuring resistance between the signal terminal 4 and the low reference terminal 3.
- Test for a minimum resistance value of 37-43 Ω and a maximum value of 245-255 Ω without any spikes or dropouts.
- If minimum resistance is not 37-43 Ω, maximum resistance is not 245-255 Ω or if there are any spikes or dropouts
Replace the B46 Fuel Level Sensor.
- If minimum resistance is 37-43 Ω, maximum resistance is 245-255 Ω and if there are no spikes or dropouts
- If minimum resistance is not 37-43 Ω, maximum resistance is not 245-255 Ω or if there are any spikes or dropouts
- All OK.
