2009 Aveo Crankshaft-Camshaft Correlation

[avguy]

I assumed the belt probably stripped out from neglect. The car has 160k miles and it was never changed.

When I did the first belt change on my '05, it was at 90K miles. We all have busy lives with lots going on, and this one got away from me and I was fortunate nothing bad happened as a result. Anyway, at 90K the old belt looked like it just came out of the box. No marks or wear cracks, even when bent backwards. The thing looked like it could have easily lasted another 90K. And the second belt on this '05 at 150K, and the first one from our '06 at 65K both looked brand new as well.
Now what you say may very well be correct, that the belt gave up after too many miles - IDK. But based on my (limited) experience, these belts are built extremely well (and need to be based on what they're being required to do). So, what I'm suggesting is to examine all of the other components carefully, to make certain there's no defect which could have been the real cause for the belt to fail.

Will a relearn fix my problem? We have access Snap On Modis. Would it be sufficient to do the relearn procedure?

then you're good to go, as i Believe the Modis actually supports the Cam/Crank Relearn procedure.

We had that done and it made no difference. Anything else we should try? We tried to go to the dealership but they are over a month out for diagnostic.

Any news on what the fix was to this problem? I am having the same issue with my aveo now and can not for the life of me figure out what the problem is.

Im having the same problem as well. Changed the cam sensor, crankshaft sensor, coil pack, plugs, wires, fuel pump (which includes filter) and added fuel injector cleaner. Mine starts no problem but still getting a code for my camshaft... so confused. Did u figure anything out sauceboss?

[Justme101]

I may add that it starts but rpms are jumpy, and car dies. It runs longer in idle (5min or so) than in drive (1-2min or so) and is worse when the car heats up verse when I first start it.

did you figure out what was your problem? I'm having the same problem I took the crank sensor out but i cannot find any specs

This isn't an Aveo but hopefully it is done in a similar way on an Aveo

Is not mention in here, so I don't think it needs to relearn

The following idle learn procedure must be performed whenever one or more of the actions listed below are taken;
•Replacement of new ECM
•Replacement of new throttle body
•Cleaning of carbon deposit on the throttle body
•Power disconnection (battery cable, ECM fuse, etc.)
1Turn the ignition ON.
2Turn the ignition OFF for 15 seconds.
3Turn the ignition ON for 5 seconds.
4Turn the ignition OFF for 15 seconds.
5Start the engine in park/neutral.
6Allow the engine to run until the engine coolant is above 85 °C.
7Turn the A/C ON for 10 seconds, if equipped.
8If the vehicle is equipped with an automatic transaxle, apply the parking brake. While pressing the brake pedal, place the transaxle in D (drive) for 10 seconds.
9Turn the A/C OFF for 10 seconds, if equipped.
10If the vehicle is equipped with an automatic transaxle, while pressing the brake pedal, place the transaxle in park/neutral.
11Turn the ignition OFF. The idle learn procedure is complete.

Try running it with the crank unplugged. A few people (including myself) had issues with terrible idle and throttle response after engine replacement. It will be driveable but not very nice if it works.
