Oil pressure sensor fuse

[Aus Nick]

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.

If the fuse keeps popping, the issue isn't the fuse.  Check the circuit wiring for any knicks or abrasiosn that might be allowing it to ground out.  If there are no conductor or connector issues, you might need to replace your oil pressure sending unit, its a cheap part.  Its located in the driver's rear of the engine, next to the transmission bell housing, right above the oil filter.

I am currently having an identical issue with my 2021 Silverado. Did you ever find out which fuse it was? I replaced my pressure sensor, but it unfortunately didn’t fix the issue. I’m hoping it was a fuse/sensor combination issue but am having trouble narrowing down the fuses. Thank you

Have you scanned for codes?  What engine do you have?

I have a 5.3L, and unfortunately I haven’t scanned for codes. I’m in the process of moving and my scanner is several miles away

On the 5.3 there is no "fuse" for the oil pressure sensor.  The 6.2 has a fuse, but its not for the oil pressure sensor.  Its for the oil flow control solenoid valve in the pump, which the new 5.3s don't use.

 

The oil pressure sensor has a 5v reference from the ECM, and then all the rest of the circuits for it are to the instrument cluster.  No fuse.  

 

Might want to try and break out that scanner or stop by somewhere and have the codes read.
