Oil Light Coming On/Off

2005 4.7L @114K miles.

So today while stopped, my oil light would chime on/off on/off (flash and chime) until I would give it some gas. I haven't had a chance to check the oil level yet, but I suspect it's fine as I just changed the oil about 3 weeks ago and haven't noticed any leaks on the driveway. I don't get any messages on the EVIC for 'low oil' either.

I searched on one of the other forums and people were suggesting either the oil sensor or oil switch?

I'm leaning towards this as well, but wanted to ask around first.

Thanks.

I have the same issue and it goes away once I restart the Jeep

The OIL LIGHT comes on and you don't IMMEDIATELY shut off and check your oil level!??

I did immediately and oil level was perfect. Doesn't sound like OP did

That is who, (OP), the posting is directed at. No offense meant.

Oil level is fine. That's why I'm leaning towards the sensor or something like that.

If it's only doing it at idle, it's pretty certainly not the sensor. Possible that it's reading lower than actual and setting the light since a hot idle will produce the least oil pressure.

Also, there is no 'low oil' light. No sensor to check oil level.

Quality oil and filter used?

It's fine while driving, then at say a stop light, it will start chiming.

I used Mobile 1 synthetic 5w30 and the Mopar brand filter. Been using this combo for about a year no issues. I'm going to check the oil again afer work while its cool and see, but I'm betting a sensor as its driving fine and no leaks anywhere.

I had this happen once and it was a flake of metal got in the sensor. Sometimes it was vertical and got a good reading and the other times it was flat and the oil light came on. Gave me stress figuring out what was going on.

I ended up just replacing the sensor .. and when keeping and fixing the old one I figured it out.

I checked the oil level again last night and this morning both hot and cold. Oil level is perfect, right at the top of the 'safety line' for hot and slightly above for cold. Still no leaks. I'm going to look at ordering a new oil pressure switch unless any here has any other suggestions?

I had this happen a few weeks ago (same situation, and all levels were fine).
I swapped out the oil pressure sensor and the problem hasn't returned.

Ill echo this. Just had to swap mine. my old sensor had a lot of oil on the outside, probably from oil in the filter
