How to Diagnose and Fix a Fuel Level Sensor B Circuit High Issue

AvatarByCarl Frisch

The Fuel Level Sensor B Circuit High is an error code encountered in vehicles that are equipped with a fuel level sensor. This sensor is used to measure the amount of fuel present in the fuel tank and relay this information to the vehicle’s computer system. When this code is triggered, it means that the voltage measured by the sensor is too high, indicating a malfunction in either the sensor itself or its surrounding wiring. To fix this issue, a technician must first inspect and test the wiring and components of the fuel level sensor system to determine where the problem lies. Once identified, it can be repaired or replaced as needed to restore normal operation of the vehicle’s fuel level monitoring system.
