So i recently got my alternator, power steering pump, and accessory pully replaced on my 2000 Camaro SS. Now the Check Gauges light will turn on and off at random. Does anyone have any idea what can be causing this?

 

The check gages light comes on when one of the gages reads higher or lower than it's supposed to.
So when it comes on look quickly to the dash to see which gage is causing it.

 

X2 ~ The only time mine ever came on on my '00 SS was when my electric fans failed & the car overheated ~ the Temp gage shot up real fast & Check Gages light lit ~ (although that was unnecessary ~ the steam coming out from under the hood was ample notification that I had a problem .

 

Mine came on when I was real low on gas .

 

But thats just it, i'll be driving and looking at them and they will be good and the light will stay one for a long while. Then shuts off randomly and turns on again while all the gauges are normal. So iono, maybe thinkin of taking it to Chevy but i dont trust them dealer people

 

Try resetting the PCM.

 

X2 With a High end scanner (like Genisys)you can cycle the gages & idiot lights ~ if you do not have a scanner, find a good mechanic who does.
