Technical Error Code : P053C

[Mi Cart]

Newbie here. 2018 motorhome on a Fiat Ducato chassis. Engine warning light comes on after 200 - 300 Km, this has no affect on performance. Leave overnight and warning light is gone. A friend diagnosed an error code P053C, positive crankcase ventilation, heater control circuit high.

My Ducato list for P053C gives Air Conditioner Pressure Sensor, totally different to generic offerings.
Certainly a difference in importance as well. Sludge in PCV not a good idea, air con not working first world problem.
