Hey everyone,

New to the forums, thought I would post my first question. I have a 2012 f150 fx4 with the 5.0. I need to change out the crank position sensor but need some help. I located the sensor on the back side of the head on the right side of the motor, but replacing it looks like quite the challenge, its a tight squeeze. Anybody have any tips for me as dar as swapping out thw CKP sensor?

Thanks in advance!

 

I think intake manifold should be removed to get at the crank sensor, for some reason I remember looking this up before...

 

Correct!
