Unusual Beeping at Start

[Jeepers2216]

So I thought I was just imagining things but now I know I'm not crazy and my 2001 Wrangler Sport is beeping weird at start up occasionally. So sometimes when I start the Jeep it will go through the regular 3 or 4 beeps but then it does 3 in a row fast beeps and I feel like my check gauges light stays on while it beeps like that but then goes off. No lights on in the dash, no issues that I know of and it only does it sometimes. I've done my Googling but Tj's are their own breed and everything out there is for newer Jeeps. Anyone else have this issue that can point me in the right direction?

Maybe try seeing if any codes are showing up with an OBDII scanner?
Probably won't but it might show something.

My jeep did something similar a few years ago. When it would beep like that I noticed there was no oil pressure showing on the gauge for a few seconds as the engine ran before the gauge would start working properly. Luckily replacing the oil pressure sender fixed my issue. As random as it happened to me it took a while to figure out.

How old is your oil filter?

Yeah I already replaced the oil pressure sending unit weeks ago because it was pegging out and I never knew if it was correct or not. All my gauges are working properly at start up, that was the first thing I checked, since it said check gauges. So who knows.

How old is your oil filter?

Just replaced 2K miles and 30ish days ago. Oil is at normal level too. Battery almost brand new. New gas cap a week ago. and I've only drove it till the gas light came on twice since I've owned it.
