Code P0463 2019 Honda CR-V Description

The P0463 diagnostic trouble code (DTC) in a 2019 Honda CR-V indicates a problem with the fuel level sensor circuit registering a high voltage. The fuel level sensor is responsible for measuring the amount of fuel in the tank and sending this information to the vehicle's engine control module (ECM). When the sensor detects a high voltage signal, it means that the fuel level is reading higher than it actually is, leading to inaccurate fuel level readings on the dashboard.
