Daewoo has determined that some Lanos, Nubira and Leganza models have experienced
incorrect fuel gauge readings caused by a faulty Fuel Level Sensor unit in the Fuel Tank.
Reported conditions include the Fuel Gauge failing to read above the “3/4” mark or below the
“1/4” mark, which is caused by the resistor card “wiper” wearing the Fuel Level Sensor
contacts prematurely resulting in a short or open circuit that triggers the false readings at the
Fuel Gauge. The Fuel Level Sensor has been improved in all vehicles produced since
October 9, 2000 by coating the resistor card with a special lubricant to prevent premature
wear of the resistor card contacts.
To simplify the repair, the Fuel Level Sensor is now available as a separate replacement part.
It is no longer necessary to replace the complete Fuel Pump Module to replace a faulty Fuel
Level Sensor. Refer to TSB-005-01 for complete Fuel Level Sensor removal and
replacement procedures.
Important: Daewoo has also noted a small number of customer comments regarding the
rate of Fuel Gauge Indicator movement as compared to the actual amount of fuel used. If the
Fuel Tank is filled to capacity, the vehicle may tend to travel more miles between the “Full”
indicator and the “1/2” mark than between the “1/2” mark and the “Empty” indicator. This is a
normal characteristic of the Fuel Level Sensor which has not been revised to change this
characteristic. Attempts to address this customer concern by replacing the Fuel Level Sensor
will
not correct this condition.
