2005 Aveo 5-spd sedan - timing belt broke - being repaired

I'd rather not hack it to get it to work. As is, the car isn't operating in closed loop which likely leads to lower mileage and less power too.

So do we believe a reprogram or crank relearn will fix the problem at a chevy dealer

Not to sound like a jackass but does this mean for future people that 2004 to 2005's should have replacement motors from those same years if needed? Was the dividing line cable driven vs. drive by wire?

I'm really not sure what is triggering this need for a crankshaft relearn. I'm actually not 100% sure that that is the problem. Its just the next thing on the list to try at this point. You might have to do it with any new engine.

Daox, any updates on your project Aveo yet? Just curious as to whats happening with it.

Well I know for a fact that the 04-05 have a different block than the 06-08 and the 09 engine is different than the 10-11...I have all the part breakdowns here since were a Suzuki dealer I did a little bit of research on the crankshaft sensor. It is a different sensor for 04-05 and 06-08. Therefore you want to use the old sensor. Unfortunately, were not automotive dealer, so I can only see the parts breakdown, not the service manuals. The link (gm.ws123.net) doesn't work anymore, GM shut them down. I'll see tonight what the procedure is when I get home tonight.

I tried using both sensors, no dice.

I still haven't taken the car to the dealer to have the relearn done.

hopefully when you do get the relearn done then that fixes the problem. You dont need more problems lol

As promised here is the CKP learning procedure. Now the other thing that could be an issue is the 07 engine's reluctor wheel. If it's different than the 04, you may never be able to get the ecu to learn the ckp. I can't check that until Tuesday.

But for now here is the file. I had to zip it, forum doesn't like .rtf files.

The timing wheel on the crank did come to mind. I guess I wouldn't be surprised if they changed it. I sure hope they didn't! That would create a lot more work for me though haha.

Thanks for the relearn procedure. Unfortunately, I don't have a scantool that can do it. Still gotta take it to the dealer.
