Fuel Level Sensor: Description and Operation
Fuel Level Sensor
The fuel level sensor is attached to the modular fuel sender assembly. The resistance of the fuel sensor changes with fuel level by means of a rheostat. Its
range is from 250 ohms with a full tank to 40 ohms with an empty tank. This resistance value is sent to the PCM. The PCM sends the fuel level
information to the IPC over Class II serial data. The fuel level sensor is also used for evaporative emissions system diagnosis.
