RE: crankshaft position sensor
It is located on the passenger side of the front cover slightly behind the harmonic balancer. Looking at the front of the engine, it will be approximately at the 7 o'clock position.
If you are replacing this component, please be aware that a CKP variation learn proceedure will need to be completed. This allows the PCM to precisely calibrate the characteristics of the new sensor to that of the engine for accurate timing control.

Just unplug the positive conecctor of battery for ten minutes. That will reset the computer and everything will be allright.

I did the computer reset unplugging the battery and worked but anyway I will do the learn procedure that you said swartlkk. Just a recommendation, that piece have a screw that does not have to be screw it to tight to avoid the crankshaft hit the sensor making the piece work failure and producing a weird sound.

It may work just fine, but you really will never know until you could potentially have a problem. A CASE learn will save you from spending a lot of money chasing problems later.
