General Descritpion
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. The fuel level sensor's 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 2 serial data. The fuel level sensor is also used for evaporative emissions system diagnosis.
