Answer 1

HI there,

Sorry to say, but usually after a timing chain replacement if you have this code it's a result of the timing chain being off on bank 2. That being said, you can use a scan tool and watch the cam position and see if it changes when you rev the engine. If it does, then it's working like it should, but the timing itself is off.
