To find the relevant fuses, you'll need to consult your owner's manual. It will show you the fuse box locations (usually under the hood and possibly inside the vehicle, near the steering column) and a diagram indicating which fuses control the instrument panel, gauges, or related circuits. Look for fuses related to the instrument panel, gauges, or possibly even the Body Control Module (BCM) as they can influence the gauge's operation.
Important Note: Before checking fuses, make sure the gauge isn't malfunctioning due to other issues. A low fuel level, a faulty sending unit in the gas tank, or even a problem within the instrument cluster itself could all cause the fuel gauge to be inaccurate or non-functional. Checking these possibilities before jumping to fuses will save you time and effort.
