(2) retaining latches.
2. Remove the Rear Seat Bottom Cushion to gain access to the Fuel Tank.
3. Remove the Fuel Pump Module Access Cover.
This bulletin supplements Technical Service Bulletin #TSB-004-01 “Fuel Level Sensor
Availability” which identified specific customer concerns related to Lanos, Nubira and Leganza
models that have experienced incorrect fuel gauge readings caused by a faulty Fuel Level
Sensor unit in the Fuel Tank.
To simplify the repair, an improved 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.
Included in this bulletin is a procedure for diagnosing the Fuel Level Sensor (commonly
referred to as a "Fuel Level Sending Unit") and the replacement procedure, if necessary,
which involves the partial disassembly of the Fuel Pump Module.
Note: Fuel Level Sensor units are not interchangeable between models.
CAUTION: Removing components from a sealed fuel system exposes fuel vapors to
outside oxygen and possible sources of combustion. The fuel system is
under pressure which must first be relieved to avoid possible spillage or
fire when removing system components. A fuel system should only be
opened when absolutely necessary, and only in a properly ventilated area
after the prescribed diagnostic procedures have determined that fuel
system components must be removed. Special caution should be used
when removing components from a fuel tank or fuel system. Removal of
such components should only be done by an experienced, certified
technician and away from open flame (torches, lit cigarettes, heater pilots
or other flames however minor) or sparks (mechanical, electrical or
otherwise) that could cause fuel vapors to ignite.
