Problem overview

Some Ram 1500 owners report experiencing issues with a faulty fuel level sensor, particularly in models from 2014 to 2017, which can lead to inaccurate fuel gauge readings. These owners have noted that when the sensor fails, it may trigger the check engine light and a Fuel Sensor Fail warning, indicating the need for replacement. Additionally, some individuals have reported intermittent failures of the fuel sensor, necessitating repair or replacement to restore proper functionality. To address this issue, it is recommended to consider replacing the sensor, which is typically located in the gas tank and connected to a float that sends signals to the gauge. Removing the truck bed can simplify the replacement process, and the cost of a new sensor can be as low as $1 on platforms like eBay.
