Code P0193 2021 Honda CR-V Description

The P0193 code on a 2021 Honda CR-V indicates that there is a high voltage condition in the fuel rail pressure sensor circuit. The fuel rail pressure sensor is responsible for monitoring the fuel pressure in the fuel rail and sending this information to the engine control module (ECM). When the sensor detects a high voltage signal, it means that the fuel pressure in the fuel rail is higher than expected. This can lead to various performance issues in the vehicle.
