P0821 Gear Lever X Position Circuit High
The P0821 code means there is an electrical fault in the circuit of the gear lever position sensor on the X axis. The main effect is that the transmission does not recognize where the lever is. It can stay in neutral or go into limp mode, so have it checked soon.
