JCB427 Engine Oil Pressure

Hi I've got a 427 loader and recently it's bringing up fault code Q0435 which is engine oil pressure data erratic. It's all got the flashing red oil warnig light on. It's doing it with the ignition on and engine not running, which is leading me to a wiring fault. The oil level is fine and the machine runs as it should. Wiring looks OK. Anyone had this before or could offer any suggestions? Thanks Karl
