Fuel Gauge Sending Unit
NOTE:
Fuel gauge sending unit may also be referred to as fuel tank sender or fuel tank sending unit.
- Fuel gauge sending unit is located on the fuel pump assembly in the fuel tank. Remove fuel pump assembly for access to fuel gauge sending unit. See REMOVAL (CELICA) under FUEL PUMP under FUEL SYSTEMS in REMOVAL, OVERHAUL & INSTALLATION - 4-CYLINDER article in ENGINE PERFORMANCE.
- Using ohmmeter, check that resistance between terminals No. 2 and 3 on electrical connector for fuel gauge sending unit is within specification in relation to the float position and distance from the center position. See Fig 1. See FUEL GAUGE SENDING UNIT RESISTANCE SPECIFICATIONS table. Replace fuel gauge sending unit if resistance is not within specification.FUEL GAUGE SENDING UNIT RESISTANCE SPECIFICATIONS
