    first. Which engine? eco tech or etechII? first and foremost. go over every single wire connection and above all else, MAKE SURE GROUNDS are all attached and accounted for, Check the fuse for the 12v outlet and cigarette lighter. The obd com port is powered through it. when you say the dash lights stay on, do you see the chec engine light as well? if you don't when the key is on, it means there is a wiring issue or a dead ecm

SOURCE: P0300 code reading on Chevy aveo. Engine light

Pull out your spark plugs. Change them if dirty. There might be a problem with the fuel trim, thats causing spark plug to foul up prematurely. A stucked open EGR valve can also cause a multiple mispfire code(P0300) but then it would be accompanied by an EGR code(P402) which means excessive flow detected. Anyways if was indeed a fouled up spark plug change them as well as the air filter.

SOURCE: 2004 Chevy Aveo cranks but won't start. Where

I believe that what you are saying is that it is turning over but will not crank...(run), not sure what your problem is, but I can help you to narrow it down. In order for your engine tp crank...start...run, you need three things to be right..#1 adequate compression, #2 ample spark, #3 the correct fuel/air mix. The first thing i would check is spark..reason, #1 failure of the 3. You can start by seeing if you have spark at the plug(S)...Just because you have it on one does not mean that you have it on all. 2nd most common failure would be no fuel...improper mix, you are fuel injected, so likely a sensor/computer issue...and the most uncommon of the 3 would be a compression issue. Which would likely not occur on all cylinders so the engine would still run, unless the cause was a broken timing belt. Gives you something to start on. Good Luck.Hope this helps.

2005 chevy aveo sometimes stalls out at lights or stop signs, lights stay on and engine light comes on. so far have been able to start right after, mechanic can't find the problem, any ideas?


Did the mechanic scan the computer for trouble codes? There must be codes there to give us a place to start looking for the problem.

2007 aveo misfire faults


gm has a problem with this from way back. double check your spark plugs and if they are not ac delcos, change them. ive seen this time and time again swearing, myself, that there is no way that the plugs would cause this issue. it always comes up with random misfire and usually another 1 or 2 codes misfire codes. put in ac delco, no more codes. let me know

Check Engine light staying on in Chevy Aveo. Yes


Many things can cause this problem...unfortunately the only proven way to remidy this situation is to have your car scanned by a reputable mechanic with a diagonstic machine $40-$80. This will tell what exactly is causing the check engine light to come on, in the long run its much cheaper replacing whats wrong than trying to replace things that arnt wrong.

Hold light blinking, check engine light on, engine slows down


check tps sensor (throttle position sensor in backside of the throttle cable) and map sensor (manifold absolute pressure on front little 1 inch sensor with vacuum line) make sure there plugged in. the ecm (engine control module driver side inner fender) and tcm (transmission control module under dash) both need the data to know when to upshift and increase fuel/air. Otherwise the computer runs default values and guesses off of other sensors giving poor performance. also disconnect battery for 15 min. usually resets aveo service lights if you dont have a scanner.

Engine will die


There is a Communication problem between the Transmission Control Module (TCM) and the Engine control module. That is the bad news and is why it's shutting down the engine. 
The good news is i believe there is a TSB recall on the 2004 - 2007 chevy aveo for the P0700 problem so it should be covered under warranty. 
Believe the TSB# 05-06-01-030D
Good luck and hope this helps and hope it's not a bad ECM. Check the wire harness to the ECM and TCM, look for broken wire or the harness it self gone apart.

Hello, I have a 2006 Chevy Aveo. I live in MInnesota and the car will not start if weather is less than 10 below. It will start right up when the temperature gets above that for an hour or so. I replaced...


The solution is to move to a warmer climate. But until u do that, here are some suggestions. Extreme cold is very tough on a car, and all systems must be operating well in order for a car to start in the weather u are experiencing. Since the engine light has gone on, have any trouble codes read that are stored on the cars computer. Most parts stores will do this as a free service. They will plug a scan tool into the cars computer port under the dash and check for the codes. Write them down and ask what they mean, and how to fix any problems. U can post the codes and any questions here for help. Make sure u are using the proper engine oil weight as recommended in your owners manual, oil that is too heavy makes it difficult for the engine to turn over in the cold. You can also check out engine oil heaters, which is just a dipstick u put in the oil dipstick tube, plug it in and it keeps the oil warm, which will be a BIG help on the cold mornings. Good luck, and spring is less than 3 months away!

Oil Light stays on.


it sounds like a faulty sending unit the only way to know for sure is to install a mechanical gauge and measure pressure. or just replace the sender. it is not wise to drive it and just assume it is nothing major. if it is a mechanical problem will cost a lot more if you lock the engine up
