Ram 1500 fuel gauge erratic and speedometer displaying incorrect speed on Ram 1500

Some Ram 1500 owners report experiencing issues with an erratic fuel gauge and an inaccurate speedometer. These problems are often attributed to a faulty Vehicle Speed Sensor (VSS), which can become damaged or corroded over time, resulting in incorrect signals sent to the ECU. Additionally, some owners find that a malfunctioning fuel level sending unit, located inside the gas tank, can cause the fuel gauge to become stuck. This unit operates using a float arm connected to a resistor strip, which may fail due to wear and tear. To resolve these concerns, it is advisable for owners to have the VSS checked for damage and the fuel level sending unit inspected for malfunctions, as both components are essential for accurate readings in the Ram 1500.
