Hot Oil / Check Engine Light and Cut Wire

Interesting...So I go to start up Gretch, and I get a HOT OIL Warning that's scrolling on my dashboard, the Check Engine Light is on (Along with a Tire pressure warning, but this may just be the frosty weather) so I popped the hood, and I find ..a mess.. The plastic cover to the bundle that houses a lot of the electrical wires has somehow cracked and be completely exposed. Likewise one single wire, (only one that I can tell so far) is severed. It doesn't look like it's been cut but rather just pulled apart. I don't think anyone would go and snip 1 single wire, so I assume this just somehow snapped, but I still find that baffling. Anyway, I can only assume that this is the cause of the sudden "Hot Oil" Warning here. There's no indication of any oil pressure or high temperature signs. In fact the Jeep runs fine, nothing different or out of the ordinary, but the fact that the sensor is tripping the Check Engine Light AND the Hot Oil Message, strikes me as something to do with this wire being cut.


Also, do you think this would be covered by the warranty? What say you folks?

nope not covered under warranty because thats rodent damage. if you are cheap like me and can find the other end of that wire, I would butt connector it together then electrical tape the wire loom. Should fix it. If it doesn't, you will have to take it to a garage/dealer for further check on the engine wiring harness.

Yes, rodent damage, and I think I can see the other end of the pink wire. Looks like a butt connector will work. I would use the heat shrink type connector. I’ll bet the insulation on the bottom of the engine cover is chewed up also. I use fir tree and peppermint essence oil dripped on an old sock full of saw dust. Reapply the oil every few months. I have not had rodent damage since using it. Good luck.

I guess the wire coating is now soybean based coating and rodent damage is rampant. My daughter's honda civic had a wire harness chewed threw and she lives in another town so I could not look at it (it would not start and is a 2017) I had her have it towed to a honda dealership and they soaked me over $400 to replace a $20 harness.

Holy crap, you all are right, in fact, it was chewed through, and even further evidence, there was literally a small "nest" of cardboard on the bottom of the bay!


And! Eureka! I was to strip the wire jacket, and salvage about a centimeter of bare copper on both ends, and twist them together. Duct tape says the rest! I cranked her up and the warning was gone! Just have to clear the Check Engine light now. Thanks everyone!

Thanks guys. Lol I like the peppermint essence oil idea... but anything a bit more "official"? something I can buy in a can or spray that won't harm the components?

I would shrink sleeve and solder that wire.

A couple of bars of Irish Spring in small cheesecloth bags tied up under the hood.
Or Peppermint Oil in a spray bottle.

Hum, 4 stars out of 2,600 + reviews.

They are working for me or I would have never recommend them. I also make my own out of the active ingredient, fir tree oil with an old sock and some wood chips. Need to change the bags or reapply oils every couple months in order for them to be effective. I only have a few new bags left, once they are gone I will be using the home made product, much cheaper for about the same product. Peace, Lee.

Yes, I’ll agree, I use these from time to time and they seem to be effective. I think the rodents get used to these pretty fast so I change things up every 6 months or so.

Haha, the Rodents are the Borg then? they adapt to your techniques? Thanks for all the suggestions though...I had no idea this was even a thing that I had to worry about lol... I'll try the Irish Spring Soap idea first and then see if any further steps are need to step it up lol..

It's more of a recent problem since auto manufacturers started using wires clad in soy based insulation. Yep, no one ever thought that rodents would like ummmm,,,,,,, food based wires.

We live in the middle of the woods as well.
We use those dryer sheets. Tried them in our snowmobiles one summer, and no more rodent shit.
We also use 'em for keeping the bugs off of us, and the dogs in the summer.
