Fuel Gauge - Inaccurate Readings
Bulletin No.: TSB-004-01
Model(s): All
Date: August 3, 2001
VIN Range: N/A
Description: Fuel Level Sensor Availability
Group: Engine
Reference: N/A

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.
