Problem overview

Some Dodge Ram 1500 owners report experiencing check engine light issues with codes 340 and 344 after wet conditions, which may indicate problems with the Camshaft Position Sensor. These issues can arise from damage or water ingress affecting the sensor and its wiring. Additionally, some owners note a possible air leak in the intake system that can lead to a lean air-fuel mixture, resulting in engine misfires and triggering the check engine light. This misfiring, or "missing," could be linked to the air leak or issues with the ignition system itself. Furthermore, owners emphasize the importance of addressing wet conditions by drying out any components that may have become wet, particularly electrical connections and sensors, as water ingress can cause various electrical problems. For those unable to identify the exact cause of these issues, seeking assistance from a qualified mechanic or dealership is recommended for a thorough diagnosis and resolution.
