Can anyone please tell me where this sensor is located on my 2003 F150 and if the intake manifold deffinately has to be removed to replace?
Thanks !

 

If you have a v8 (4.6 or 5.4) it is located on the drivers side head toward the front in the valley under the intake manifold. If you have a v6 engine it is located on the passenger side head all the way in the rear. I believe the intake may have to be removed to get to it on the 4.6 and 5.4 engines.

 

Thanks for the info greenego
