If you already replaced the CCT, then you should be good. If it's a light tick, then it may be the injector tick you can sometimes hear. Your valves do not get bigger clearances to cause a tick, just the opposite.
The '03 was exempt from the valve guide tick that affected some '04-'05's. That was due to valve guides worn/too big in the first place.
Never a bad idea to do a valve check if it's been a while, but extremely doubtful you'll have any clearances too big....
I can't advise you any better without actually be standing there hearing what you're describing....... how many miles? I'm not sure an injector cleaning would lessen the tick.....
