Anyone know where it is located and if it is easy to change ?

A photo would definitely help !

 

It's right next to the crank pulley, on the firewall side too... You'll have to take the entire plastic covering in order to access it, and I believe the sensor is somehow built-into the covering as well. So be careful when taking it off.

 

Ok, I took off the plastic cover and I don't see any sensors anywhere

The only electrical harness is the connector you see in the photo, it leads to somewhere under the block.

Is it on the bottom half of the engine block ?

 

IT SHOULD BE ON THE BOTTOM!!!!

as you know the crank shaft its at the bottom of the engine

did you find it?

 

Sorry EdT, let be better explain where it is...it's right behind the crankshaft pulley. You can't access it or see it until you remove the plastic covering and the pulley itself. The "lead" wire for the sensor is built into the plastic timing cover, so don't damage it.

Good luck!

 

Not easy but its doable, just be careful as SLVROZ_03 said with the wiring, this is where the sensor is if you still cant see it
