There's only one way. Put a known good PCM in and see if it works better.
No, the years have to match.
If the Neon's are both the same year and have the same engine type then the PCM should swap out ok. If the engines are different then the PCM may not work properly.
The PCM on a 2003 Neon is between the radiator and the transmission under the hood.

Code 52 on a 1998 Dodge Neon typically indicates a problem with the powertrain control module (PCM) or the circuit related to it. To fix this, first check the PCM connections for corrosion or damage, ensuring they are clean and secure. If the connections appear fine, you may need to test the PCM itself for proper function, which could involve replacing it if it’s faulty. Additionally, inspect related wiring and sensors for any issues that could affect the PCM's performance.
