NOTE:

The fuel tank must be filled completely in order to have an exact reading of the resistance value at "Tank full" when it is installed. Drive at least 500 meters after completely filling the fuel tank to get rid of any bubbles in the fuel tank. Then fill the fuel tank again.

The contact assignment -2- at the connector is dependent on the model.

-- Connect the multimeter for resistance measurements shown in the table.

Measurement at Contact Tank Empty Tank Full
Vehicles with 4-cylinder engine: 1 + 4 275 to 303 Ω 51 to 71 Ω
Vehicles with 5-cylinder engine: 2 + 4
Vehicles with 4-cylinder engine: 1 + 6 44 to 70 Ω 269 to 289 Ω
Vehicles with 5-cylinder engine: 2 + 6
4 + 6 1) 335 to 345 Ω 335 to 345 Ω
1) Arbitrary sensor position

Fuel Level Sensor 2 -G169- is Removed, Except Country Specific NAR

NOTE:

To check the resistance values "tank full" or "tank empty", the fuel level sensor must be removed and the sensor floater must be moved to the upper or lower stop.

With the fuel level sensor removed, the following values are obtained because of the greater movement of the floater arm:

-- Connect the multimeter for resistance measurements shown in the table.

Measurement at Contact Tank Empty Tank Full
2 + 3 297 to 303 Ω 51 to 53 Ω
1 + 3 37 to 43 Ω 281 to 289 Ω
1 + 2 1) 335 to 345 Ω 335 to 345 Ω
1) Arbitrary sensor position

The Fuel Level Sensor 2 -G169- is faulty if the following is found:

-- Install the Fuel Level Sensor 2 -G169-. Refer to Fuel Level Sensor 2 -G169-, REMOVING AND INSTALLING .
