Fuel Level Sensor Tables
WARNING: This page is about a different car, the 2014 RAM 3500 HD and 2014 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.
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. 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.

NOTE:
The diesel engine end stop and 1/2 tank values are the same.
