My 2013 Equinox 2.4 had the same code at ~97k miles. I replaced the intake and exhaust VVT solenoids and cleared the code. My daughter’s 2010 Cobalt threw a related code (P0014) recently, I removed and cleaned both solenoids and the code has not reappeared. The solenoids are easy to replace on the Equinox.
