After changing timing belt on 2010 Chevy Aveo keep getting check engine light code P0366Type your question here...
Greetings and welcome back!!!!!

Changing the drive will not have anything to do with this at all. How many miles on your vehicle and what model Aveo is it? This is a code for a signal problem on the exhaust cam phaser.

It's a Aveo LT with 67400 miles. Had a mechanic do it and he is telling me that there is a spring in the exhaust cam and if it stretches it could have something to do with the code

I am sorry I did not see the timing belt, I read drive belt. Yes there is a Cam phaser that has a spring in it. I would first recheck the timing belt alignment to make sure that it is not off a tooth, but it could just be the phaser went bad. So It could have been caused by the timing belt replacement. If they replace the phaser and it returns, could have just been caused by the tech in the first place.

Where is the phaser located ? Is it a part of the camshaft. Mechanic told me he was going to change the camshaft!!

No not at all. There is one on the exhaust side and one on the intake side. This code is for the exhaust side.

I wish there was a repair manual for this vehicle. I'll inform the mechanic and find out if he checked it.

There is online repair manual. Look up alldata diy online. there is a monthly subscription fee though.

Is the name of the part the Cam phaser? I could not find it online at Autozone auto parts.

Actually they call it Camshaft Position Actuator Solenoid Valve.

Thanks again,very helpful

Sorry I gave you the wrong picture. It is called a camshaft position sensor exhaust side.



Customer: replied 4 years ago.

Checked with mechanic he said he tested the sensor and it was OK. So he ordered a new camshaft. He thinks may have forced the cam and caused the spring in it to stretch. We'll see what happens should get it today and he can replace it tomorrow.

No problem. Let me know how it goes.

Customer: replied 4 years ago.

I sure will. Thanks again for your help.
