Strange chime at startup, anyone know what it means?
 
Background info - 01 wrangler 6 cylinder manual transmission.

Recently (for the past 3-4 days) my jeep makes a chime sequence that is different than the norm at startup. Typically there will be the chime that beeps a few times slowly, and then is done.

However, recently there have been 3 short chime beeps after the longer chime beeps. I'm not sure why this is. On top of this, two times today it did the 3 short chime beeps on startup, and then flashed the "check gauges" light for about 2 or 3 seconds, and then the light went off. When this occurred, my jeep idled a little rough when it first started, but once I revved it up a bit she ran as normal.

When the "check gauges" light comes on, there are no other lights on. The check engine light is not on. Also, the check engine light DOES come on momentarily at start up (like its supposed to, with all the other lights) so my check engine light is not burned out.

Anybody know what the 3 short chimes means?

And does anybody know why the "check gauges" light would come on when there is seemingly nothing to check? All of the gauges read normally.

Thanks in advance for any input! :)

does any gauge reading seem delayed?

I think I may have figured out why it is doing this. My oil pressure does not come up as quickly as it used to, and I beleive that is why it is chiming. That definitely has me concerned though, since the few moments during startup is the most crucial for a motor in regards to oil flow. I just had my oil changed before the weekend, I think i'll be going back to the place that did it and asking them a few questions.

that's what i was implying at you in my reply above

Any follow up on this one?

My suggesion would be to go to a Jeep dealer and buy a new OEM oil pressure sensor. The 3 chimes occur because the check gauges light came on. Check gauges light it sounds like is coming on because the oil pressure is not coming up on the gauge fast enough. Those oil pressure sending units cause all sorts of false pressure readings. Get a good one, not a cheap one from the auto parts store.

Follow up -

It was in fact an oil pressure issue. I took it to a more reputable shop and had the oil changed again, and the problem went away. I'm not sure what the original shop did, but I would guess they put in a drastically wrong type/weight of oil. It still comes up a little slow, but its quite a bit faster than it was before. Before I had the 2nd oil change, there were startups where the pressure gauge stayed at 0 for a few seconds- very worrying.

Same thing happened to me today! So normally when my rig acts weird electrically,I just punch it in the passenger side airbag starts up fine no chiming:) so long story short happened today heading to all places autozone after talking to Charlie old school jeep guy found out it was my oil filter changed to a new one (Mobil ) and she is running fine. I would try this first

So is this an issue with the oil filter or the sensor? The jeep has been doing this everytime it starts up now. After a few seconds, it works fine, but at startup, the pressure is 0, so I wasn't sure if it's just a messed up sensor or clogged one or what.

Could be the sensor, filter, oil, or wore out engine bearings. Mine was doing it but I knew my bearings were bad so I ignored it. Finally broke a piston skirt and dropped a brand new engine in it. Still doing it, so I replaced the sensor and now it's fine.

Some cheaper filters use a rubber anti-drainback valve. Try to buy a filter with a silicone ADBV.

Lots of google info on this, and I have had trouble with dry starts on several vehicles.

I think (but research it on your own) that WIX filters are silicone ADBV, and I know the Purolator Pureone premium filters do as well. Basically, you have zero oil pressure at startup if the filter has drained itself of oil since the pump has to fill the filter before pressurized oil gets to the rest of the engine.

Could be another problem, but my money is on faulty/cheap filters. WIX are made in the USA as well (I think).
