Good morning, I have a 2020 Silverado 1500. 6.2. twice in approximately 1000klm it has suddenly dropped oil pressure and engine light has come on. On inspection by the side of the road oil level was good and no signs of any leaks. Engine started again fine and wasnt rattling like they do with no oil pressure. took it to local dealer and apparently it’s a fuse. Now it has happened again on my way to work hours away from help. My question is, is there a fuse for it and where is it? Thanks for any assistance, it’s appreciated.
