Many modern cars and trucks are equipped with electronic fuel gauges that have a built-in self-test procedure. If the fuse is blown, replace the fuel and verify if this fixes the fuel gauge. Using your owner manual again, check where the fuses are located for the fuel gauge and pull the fuse to check it’s condition. If other gauges besides the fuel gauge are acting up, it may be a fuse related problem. Sometimes when fueling a vehicle with the ignition on or engine running, the rapid change in fuel level can cause the system to throw a trouble code. P0464 Fuel Level Sensor Circuit IntermittentĪll codes can be related to electrical faults, so be sure to check all connections and grounds in the circuit.P0463 Fuel Level Sensor Circuit High Input.P0462 Fuel Level Sensor Circuit Low Input.P0461 Fuel Level Sensor Circuit Range/Performance.P0460 Fuel Level Sensor Circuit Malfunction.If the fuel level sensor circuit is having issues, the most common OBD-II codes related to the fuel sending unit are: To find the fault, use a OBD-II scanner or code reader to read the codes through the vehicle’s OBD port. If the check engine light is illuminated on the dashboard, this means a fault is detected with one of the vehicle’s monitored systems. Scan for OBD-II trouble codes (if the check engine light is on) But before jumping to conclusions and trying to fix something that may not be broken, there are some simple inspections and tests that can help streamline the repair. A fuel gauge that reads full or empty all the time, or has a needle that moves erratically, could be the result of a faulty sender unit or fuel gauge itself.
