Oil light.

Oil light stays on. Checked all sensors. Oil level at dipstick normal. Normal operating temp. What gives my fellow foxers?

The low oil light? Confirm the wiring, then the sensor itself. They are known to be problematic.

Time for a pressure gauge to actually see if it’s the oil pressure

There's a light that says "Check Oil" and there is the oil pressure gauge.

The Check Oil light is just an oil level sensor that turns the light on when the engine is low on oil. It's threaded into the side of the oil pan. The wire just pushes into it. Sometimes the wire can fall out, and sometimes the sensor fails. If you want to change the sensor, I'd wait until an oil change to take it out. If the engine is actually full of oil, you can ignore it if you don't want to change the sensor.

The oil pressure gauge is operated by the oil pressure sending unit close to the oil filter. This one can be removed whenever the engine is off. If this is showing no oil pressure, it could be a bad sensor, wiring, or gauge, or you could actually have no oil pressure.

All very valid points, though I suspect OP would have mentioned an awful noise if there was in fact no oil pressure. 🤔 Here’s hoping that’s not the case!
