P0463 OBD2 Diagnostic Code for Dodge Ram 3500 Cummins Diesel Engine

Model: Dodge Cummins 3500 Fault Code: P0463 Posted: 2015-11-12 20:00

I'm looking for detailed information on the P0463 diagnostic code that appears on a 2018-2023 Dodge Ram 3500 with a Cummins diesel engine. The truck suddenly died while driving, and the check engine light came on. The P0463 code indicates a problem with the intake manifold pressure sensor (or vacuum leak) in the emissions system. This issue can lead to poor fuel efficiency, rough idling, or engine stalling. I need accurate troubleshooting steps, possible causes, and repair options specific to this model and engine type.
