Code P0046 2017 Honda CR-V Description

The P0046 diagnostic trouble code (DTC) in a 2017 Honda CR-V indicates a fault in the turbocharger wastegate control actuator circuit, specifically a range/performance problem. The wastegate control actuator is a crucial component of a turbocharged engine, as it regulates the amount of boost pressure provided by the turbocharger. The actuator opens and closes the wastegate, controlling the flow of exhaust gases to the turbocharger, thereby managing the boost pressure and preventing overboost conditions.
