The trouble code P5072 on a 2005 Dodge Neon indicates a problem with the idle air control system, specifically that the engine control module (ECM) has detected an unexpected signal from the throttle position sensor (TPS). This could mean that the throttle is stuck in a position that affects idle speed, potentially due to a vacuum leak, a malfunctioning TPS, or an issue with the idle air control valve. It’s advisable to inspect these components and their connections to resolve the issue.
