I need to know all P code numbers that are currently setting in the powertrain control module after parts were replaced, codes were cleared, and the engine light came back on. The codes start with a P and have four digits.

If the brake switch has been replaced with a known good part then the P0572 is being set by a wiring or possibly a connection issue.
If there are no exhaust leak upstream of the catalytic converter, and the downstream [oxygen sensor](/topics-oxygen-sensor-dodge/) wasn't replaced while leaving an aged, lazy upstream sensor in place, then the catalytic converter will need to be replaced to repair the P0420.
