My check engine light is on my chevy aveo 2005 dashboard and my car battery keeps dying when I went to get a diagnoist I was told that the battery, starter, and alternator are all good but I notice that if I leave my car over night recently the battery dies and I need a boost. Auto Zone said that the code is reading a sensors problem?

Check the cars battery
When power is to low it will causes lots of funny noises

Engine light lit ? Have it checked for DTC'S - diagnostic trouble code's ! Do you know what DTC'S are for ?

Your alternator is not charging the Battery, I would replace the battery with a new gel battery and have the alternator checked, bets on your battery just died.

The illumiation wires can just be capped off they aren't always used on aftermarket radios. It could be fluke instance that your battery died and you got the check engine light. I would take it to your closest autoparts store and have them read the codes most will do it free of charge and go from there.

your brake fluid is low. I have a 2005 aveo that i took to dealer under warranty and told them the clutch didn't feel right and the brake light kept coming on. they told me they have not seen either issue i complained about charged me 700 dollars in labor and rental fees and sent me on my way. I then proceeded to take it to the used car dealership i bought it from and they bled the clutch and said they got alot of air out when chevy told me they didnt get any. Anyway about 3 weeks later the light was on steady and the clutch began acting funny again. I bled the clutch myself this time and didnt check the fluid level or i would have caught the next dangerous part. On the 2005 chevy aveo hatch back i have with a 1.6 5 speed shares one reservoir for brake and clutch fluid. I was driving along one day down a 12% grade about 2 mile long stretch and my brakes failed. I filled the brake fluid reservoir at first chance i got considering my arm was sore from operating the hand brake for 6 miles or so. the light went out. It will probably come back on as did mine. the leak in my system was a check valve under the brake master cylinder. be careful until you get to fixing it.

It could be a few things....I just had this same problem with my 2008 chevy aveo this week. Also, my check engine light came on the very next day after the gear shifter started locking. I called Bob Bell and they told me that the gear shifter locking is probably due to a sensor going bad that tells your car it is in park. However, after taking my car to my brother-in-law (who has very LITTLe knowledge about repairing cars), we discovered that my brake lights were not working either. He told me that is why my check engine light is on - because it is extremely dangerous to drive without brake lights. We checked the fuses to make sure there was no fuse blown and they were all just fine. So bottom line, the problem was that there is a brake switch under your dash board where your brake is. My switch keeps sticking and will probably eventually need to be replaced. When the switch works properly, my brake lights work fine, my gear shifter unlocks and my check engine light goes out. Not sure how much it is to fix this switch if that is the problem but I hope it helps!

check the fuel pump and related electrical system and fuses. The aveo doesn't have a fuel filter but only a screen at the bottom of the pump. I had to replace the fuel pump in my 2004 aveo at 80k due to a clogged screen. Hope this helps

Check to see if the ignition fuse is blown.

ur dash has a bulb that lightes it up u will need to pull out the gages and find it
