Question about Chevrolet Aveo 5

1 Answer

I have a 2007 Chevy Aveo LS 5-speed manual transmission hatchback. It's been a great car so far, no major problems, great gas mileage, etc. It now has 36,700 miles on it. As per the maintenance schedule (and I realize I was a little late in getting the 30,000 mile stuff done),I just had the spark plugs and wires replaced, a new serpentine belt installed, brakes cleaned and adjusted, and the brake fluid replaced. My check engine light now keeps coming on. The car runs smoothly, nothing seems out of the ordinary. The light only comes on sporadically. Some days, it doesn't come at all. Then it'll come on and stay on. The next day it won't be on. I have no idea what's going on. When I had the car in the for the above-mentioned work, they ran a diagnostic on the car but it didn't pick up anything wrong - or at least the mechanics didn't tell me anything out of the ordinary showed up on the diagnostic. I've been taking my vehicles to this same Auto Lab repair place and I trust them. But this check engine light thing is bothering me. Any ideas? Thanks very much!

The problem is intermittent and might not have shown up when you had it in for service. You need to have it scanned when the light is on take it to autozone or similar when the light is on they will scan it for free.

One question, have you replaced the ECTS (Electronic Cooling Temperature Sensor)? These cause no end of different seemingly unrelated problems on Saturns. Peice is about ten bucks and is an easy install. Just search on youtube for a how-to video. Even if that's not the problem it is reccommended to replace this peice just the same as they ALL end up going bad at some point.

If that's not a fix, start pulling plugs. Check to see if they're correctly gapped and if they have any damage/corrosion. If you're running Platinum plugs, immediatly change to a copper plug as Platinums have no place in these motors. Most people have the best luck with NGK copper.

Check to make sure that your plug wires haven't been crossed. This sounds like a plug or wire issue most likely so it has to be in that family, if the plugs are good, wires good and not crossed, sensors are fine, then time to replace your coil packs. If you've replaced everything up to the coil packs then that is most likely the cause of your dillema.

Perform a general tune-up - checking plugs, plug wires, belts, coolant, filters and timing. Check the alignment and wheel bearings. Check the engine compression. Check the hoses for corrosion.You just want to kind of look everything over real good and see if there is anything worn like belts and hoses. Other than that just keep maintenance up.

SOURCE: 2006 Chevy Aveo Check Engine Light coming on and off

It needs a code scanner hooked up to it,to tell you why the light is on and the cause. If there is an autozone near you take it there or
call different auto part stores to find out if they do that.Without getting the code, it's just guessing what the problem is.

My chevy aveo 5 hatchback door wont open what can I do to fix it


I removed the panel on the hatchback from the inside; there's a metal rod that goes from the lever to the latch. You can move the rod to open the hatch. There's a plastic clip that keeps it all together. On mine that plastic clip is broken. Trying to figure how/where to get a new one. You'll need small hands...

Chevy aveo 2007 5door, shift handle feels lose, car goes


if its a 5 speed, yes the shifting is loser than normal cars. the reverse is all jacked up.. if its anything like my 06 aveo when you shift into reverse you have to lift the little circle thing on your shifter up ad act like your putting it into first.. If it grinds try doing it slower. I HATE this transmission. Chevy did a horrible job on picking it. I always grind reverse no matter what
