P20A2

DTC P20A2, sometimes indicated as P20A200 is an OBD diagnostic trouble code indicating a manufacturer-specific fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing reductant purge control valve circuit low.

The reductant purge control valve circuit low fault code is triggered when the reductant purge control valve circuit is low on voltage. This can be caused by a number of factors, including a bad reductant purge control valve, a bad wiring harness, or a bad electrical connector.
If you experience this fault code, the first thing you should do is check the wiring harness and electrical connector for damage. If they are damaged, repair or replace them as necessary. If the wiring harness and connector are in good condition, then you may need to replace the reductant purge control valve.
