The Check Engine Light may illuminate due to a defective charcoal canister vent control valve. The charcoal canister is a component in the Evaporative emissions (EVAP) system.  Our technicians tell us a failed vent valve will require replacement.

Screws inside the intake manifold can become loose causing internal engine damage if they fall out completely. Our technicians report that using a strong thread locker on the power valve butterfly screws can help prevent them from becoming loose. The manual transmission models reportedly do not have the intake manifold power valves.
