Fuel Level Sensor Tables

2023 Jeep Grand Cherokee Trailhawk 4xeSECTION Fuel Level Sensor Tables
WARNING: This page is about a different variant/trim than selected.

The table below gives approximate internal resistance and raw voltage values for a Fuel Level Sensor based on fuel volume. These can be used as a general reference when the actual values are not available for any single tank or saddle tank Fuel Level Sensors.Β  As can be seen in the table, the full travel of the sensor (Full Stop/Empty Stop) is slightly more than the full tank and empty tank thresholds used for the fuel gauge.

Generic Fuel Tank Table Values
Fuel level reading Typical resistance of level sensor (Ohms) Typical raw voltage signal input (volts)
Full Stop (Max full travel) 50 - 60 0.5 - 0.7
Full tank 60 - 75 0.75 - 1.0
1/2 tank 160 - 225 1.6 - 2.2
Empty tank 725 - 770 3.4 - 4
Empty Stop (Max empty travel) 930 - 990 3.9 - 4.5

The tables below are for L-body vehicles.Β
