Can't get the check engine light to go off ans some more stuff on 2001 Chevrolet Venture

OK, I love my van, don't get me wrong but a few weeks ago it took 5 hours to replace the temperature gauge. sigh. Now the emissions failed with the code for the cam shaft positioning sensor. Well, after the sensor broke inside the slot and another 4 hours spent getting it out, we got the new sensor in. Now the check engine light will not go off and the engine is making a funny sound it wasn't before. WTH? How do we get the light to go off? On top of that, after we cleaned up and went to shut the rear hatch, it will close but won't latch, leaving me with a useless van and 4 kids to haul around. Please help! :)

the sensor may be hitting something and after repl sensor the crankshaft sensor needs to be relearned with a scanner. if you repl with after market some of those sensors need to be shimmed out and shims should have come with sensor
