SOURCE: change serpentine belt and tension pulley and idle pulley and

could be the alternator, water pump
take the belt and spin all the pulleys and listen for noise and make sure they turn smoothly
another trick is to take a can of wd40 or equivalent and spray the bearings 1 at a time till the noise goes away or quiets down

Make sure you locate the Serpentine Belt Routing Sticker before you proceed. If not make an excellent drawing and take a GOOD Picture. Do NOT try to just remember how it goes back on Should be a 15mm wrench to loosen tensioner to remove belt. Locate mounting bolts to tensioner and remove, replace with NEW tensioner tighten bolts then use wrench arc torque about 15 degrees should snug it down, reroute belt then using 15mm pull tensioner to either side of belt to install belt in correct route. Remove all tools and body parts from engine bay. Do not start engine if anyone is in the vicinity of engine bay. Belt may fly off if you did not do it right and cause all kinds of shrapnell, if it doesn't fly off, visually inspect belt before starting and after, I would suggest being very careful before during and after starting to insure safety.

SOURCE: I need a serpentine belt/routing diagram 2000 chevy tracker.

For the 2000 Chevrolet Tracker:

Most modern vehicles have the Belt Routing Diagrams on the undeside of the Hood. But the sometimes disappear.

I do not know if you have the 1.6L In-Line 4-Cylinder, or the 2.0L DOHC In-Line 4-Cylinder. Nor what Engine Options you have (AC/No AC, etc.).

Let me know if this helped, or if you have additional information or questions. Feel Free to contact me at FixYa.com!

SOURCE: how do you check and change a camshaft position

The camshaft sensor wouldn't explain the clattering noise. But a timing chain would explain both. Clattering from a loose chain and the camshaft sensor code from when the chain broke and the camshafts stopped turning.
