Code P003A 2018 Honda CR-V Description

The P003A diagnostic trouble code (DTC) in a 2018 Honda CR-V indicates that the turbocharger wastegate control actuator position has exceeded the learning limit. The wastegate control actuator is responsible for regulating the boost pressure produced by the turbocharger. When the actuator position exceeds the learning limit, it means that the actuator is not functioning within the expected parameters set by the engine control module (ECM).
