2008 Chevy equinox won't start

Hello, Always avoid clearing codes unless it is needed for a diagnostic step. This code means the PCM (powertrain control module) has detected misalignment between the camshafts on bank 1. This may be a camshaft position sensor, the variable valve timing actuator may have failed, or the circuit or PCM has a defect. This will take a little testing, and a professional diagnostic scanner will be necessary to avoid throwing parts at the issue.
