NH 2006 L185 wont move forward or backward

[MSGretired]

New Holland L185 starts and boom and bucket controls work fine but drive motors will not move skid steer this is a standard control unit with foot pedal boom and bucket controls. The AIC posted one current history fault (charge pressure 254) I suspect this may be the problem but do not know where to look for the charge pressure sensor or switch or what else to look for. Please help
