Fuel Tank Unit: Description and Operation
Fuel Gauge Sender Assembly
The fuel level sensor (1), 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 90 ohms with a full tank to 0 ohms with an empty tank. This resistance value is sent to the Instrument Panel Cluster
(IPC) and displayed on the fuel gage. It is also sent to the PCM over Universally Asynchronous Receiving/Transmitting (UART)serial data, and
used for evaporative emissions system diagnosis.
