I'm trying to help my wifes coworker, she has a 2003 Chevy Trailblazer LTZ and it has two codes. P0014 and P0440.
P0440 - Evaporative emission control system malfunction. It's probably just the gas cap so I told her to buy a new one and see if that fixes it.
P0014 -Camshaft position B - Over advanced - Bank 1
I was reading that dirty oil could cause this, do you think using that ATS cleaner will help?
P0440: If replacing the gas cap doesn't fix the issue, you might want to check for leaks in the EVAP canister and fuel tank.

P0014: You want to check the Exhaust Camshaft position actuator solenoid if it has gone bad. As far as the ATS cleaner goes, check and see if there is any oil or carbon built up.
