Thanks for the video. Can a bad tensioner cause timing to be out? I have the 1200 and 1208 codes but my engine number was not supposed to suffer from idler sprocket wear.

Lack of oil change intervals can cause it

Chain tensioners on m272 and m273 do not go bad usually. It's basically a simple high tension spring. You most likely have a stretched chain which causes the intake cam on bank1 to go out of timing. Cam shaft sensor picks up that problem and reports to computer, it then throws the code 1200 and 1208.

@kijijiuserkijiji346 Most of the shops or car owners ignore those early codes stored on ecm. Also, not many shops are trained or certified
