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.
