I have P0016 and P0017 error codes -- I am stuck trying to figure out if it's the CKP sensor. I have looked under the hood, and found a sensor (I believe) just hanging there, but am unsure if it's the CKP sensor or something else? Also unsure of where it is suppose to be plugged in to. I can't attach pictures here, so please email me "firebird34" AT "gmail.com" and I can send you the picture of said part.

The vehicle has an idle of around 750 -- and no other "unusual" sounds or anything. Any suggestions on having both of those codes pop up?
