A check engine code 72 on a 1996 Plymouth Breeze isn't a standardized OBD-II code. OBD-II (onboard diagnostics) became mandatory in the US for the 1996 model year, but the specific code numbers varied significantly between manufacturers. Chrysler/Plymouth used their own proprietary system before fully adopting the standardized OBD-II codes.
Therefore, code 72 for a 1996 Plymouth Breeze would need to be looked up in a Chrysler/Plymouth specific repair manual or diagnostic chart for that year and model. A generic OBD-II scanner won't be able to interpret it.
