Check Gauges Light

Hi - I have a 2005 Wrangler. Just recently my "Check Gauges" light is coming on. It comes on when I start the car - all the gauges seem fine - within normal ranges. I turn the ignition off and restart it, and the light doesn't come back on. The vehicle seems to be running fine - I just don't want to be running it if there's a chance I'm damaging it.

I have done some surfing, and it seems to be that maybe the sensor for the light is just faulty.....sounds logical, but I don't know. It has just started getting cold (below freezing) here in upstate NY, so I'm wondering if that's affecting it.

thanks for any ideas?

First you need to check for a code. Turn your key to the on position, then off. do this two times rapidly then turn it back to the on position. You should get a reading in the odometer window telling you if there is a code. If there is no problem it should just read "done". My 06 does that when it starts getting cold out and the reading is for a slow response on an 02 sensor. It will stay on for a couple of starts then magically go away. I've been running that way for a couple of years with no problem and since I take it for emissions in the fall, the light is not on and it passes. Just remember that the CEL should come on every time you start the engine and go off within about 5-10 seconds. If you do get a code, there are several sites that will tell you what it means or you can post it up here and someone will tell you what is going on. Hope this helps.

I had the same problem...Gas tank cap not getting put back on tight will cause the check eng. light to come on...Allows air to enter the tank thus the light. put a thin coat of pertroleum jelly around the gasket inside the gas cap....helps to make a better seal for the cap.

I am having the same problem. I noticed that my check gauge light blinks on and off along with the extra chimes. I looked at my gauges and everything is normal. I have a new alternator, new battery and have done an oil change. The only other thing I could think of was the coolant levels. I checked that also and all is good. The jeep runs good. I noticed the problem during the hot days of summer when the car ran for a long time. It would occur during start up after driving it for a while. Its not doing it much during these cold days. Does anyone know what it could be. Could it be because I used Prestone Coolant and not Mopare?

It sounds funny, but a loose accessory belt will cause this too. Wife recently went through deep water too fast, and the "check guages" light came on, along with a squeel from under the hood. It went out in a few seconds, so I assume that the belt got wet, slipped/squeeled and basically stopped turning for a few seconds, causing the alternator to stop charging, setting off the "check guages" light.

Just for laughs, check your accessory drive belt for wear and slippage. When starting in cold/wet weather, an old/loose belt will set this off until it warms up/dries out.

Thanks a lot Mr. Adams. I also put in a new drive belt this summer, but you made me think about a minor leakage, just a little seepage that is coming out of my upper radiator hose were it is connect to the radiator. I am wondering if the leakage could be dripping or splashing on the belt when I am driving long periods of time causing to wet the drive belt. Well I bought a new hose and just haven't replaced it yet. I will try that next this weekend. Again thanks so much. I will let you know of my out come.

The computer turns the check gauges light on when one of the parameters displayed by them is out of the normal range. All of the gauges in the '05 and '06s are driven by the computer which monitors the sending units.

If it only happens when you start it and then goes away upon a restart, my best guess is that your oil pressure is slow to come up to spec and the light is turned on. When you restart, the system is primed and the oil pressure comes up quickly. It could be caused by an oil filter that is leaking oil back into the engine overnight and it then takes the oil pump a few seconds to refill it. Cold oil is thicker as well.

Does anyone know of a good garage in the Austell, GA area that I can take my Jeep. Its been two years and I am still having the, "check gauge" light issue. I have replace the radiator because it had a crack right in the seam, water pump, alternator, thermostat, drive belt and upper radiator hose. The check gauge light hasn't been coming on often but when its hot outside and I have driven it for and long period of time. After parking it and then restarting it before it cools all the checks and chimes go through and then there is a extra chime and the check gauge like blinks on and off very quickly, if you blink you would miss it. I have given up. I also notice that after driving for several month i have to add coolant not to the radiator but to the resivour. Its not empty but it does go down. I don't know if that is normal for Jeeps.
