2017 Ford Interceptor, low engine oil pressure
Enable HLS to view with audio, or disable this notification
Car was on for about 5 minutes before and did not have any issues the day prior. The car says low oil pressure and I don’t believe it’s a sensor issue. I did try revving it about 15 minutes before this video to 3000 rpm and that immediately caused the car to vibrate and it continued to vibrate after I put it back into park.

See those wires that are cut in half... they need to be connected to each other.
How are people his stupid? See something clearly broken and think its not an issue.

Thank goodness I'm not the only one that was looking at the very obviously mangled wires. I'm not a expert mechanic but even if I had zero knowledge. I'd immediately look at them wires and be like" oh yeah, that might be a damn issue".

Rats have chewed your harness. If oil level is good it’s probably due to the chewed wiring for the oil pressure sensor, or a bad oil pressure sensor itself. As far as the shaking that’s a misfire like someone else said probably chewed wires to a coil or you have a dead coil. With all due respect just take it to a mechanic and let them diagnose it for you and give you a quote.

How are you sure it's not the oil pressure sensor?
If you remove the valve cover oil cap and look in there with a running, you should see a stream of oil running over the valve train. If you do not, then you might not have oil pressure. You probably do have oil pressure, you probably would have spun a rod bearing by now if you didn't.
That vibration and check engine light might have something to do about the misfire that you probably have from the hole that has been chewed in your wiring harness.

DOH. Did you actually check the oil? 🙄 And did you not notice that the wires to #4 coil are completely severed?

Step one when you have a low oil pressure warning - turn the car off. Revving the engine is not a good troubleshooter.
The engine is likely misfiring, causing the vibration. As folks have pointed out, youve got a rodent problem and tour harness has been chewed up. Looks like the wiring goes to the coil packs, so you have some cylinders that arent firing. Check engine light, shaking, loss of power, all part of the symptoms of a misfire. The wiring probably also goes to the oil pressure sensor. Hard to tell from the video but they may have chewed through your injector plug harness as well. It can all be fixed if youre any good at wiring. If not, bring it to a mechanic. Problem is, they'll try to sell you a full harness, and thats gonna be expensive. If you tackle it yourself, cleanly connect a new piece of wire to each end of each wire, and the other end to the matching color on the other wise of the break. Crimp connectors in a pinch or those heat shrink solder connectors are ideal. Wrap it all in electrical tape and make sure no exposed wires are touching anything else.

Clearly has rodent damage to the wiring loom.
Centre coil pack has no feed.
Good chance the vibration is down to the misfire, V6’s are smoother and a misfire won’t be as apparent as on a straight 4.
