The 2002 Dodge Neon's power steering pressure sensor isn't a standard component like it is on some other vehicles. The Neon's power steering system doesn't typically use a pressure sensor in the way you might be thinking. Instead, pressure is managed through the power steering pump and rack and pinion assembly itself. There isn't a separate sensor to monitor it for the engine's computer.
If you're experiencing power steering problems, the issue likely lies with the power steering pump, the rack and pinion, low power steering fluid, or a leak in the system. A mechanic would need to diagnose the specific problem.
