Code P0235 2017 Honda CR-V Description
The P0235 diagnostic trouble code (DTC) for a 2017 Honda CR-V indicates that the turbocharger boost sensor is reading a value that is out of the expected range. The turbocharger boost sensor is responsible for monitoring and regulating the amount of boost pressure generated by the turbocharger. When the sensor detects that the boost pressure is outside of the predetermined parameters, it will trigger this code. This can lead to a variety of performance issues and potentially cause damage to the engine if not addressed promptly.
