ok i cant seem to get to the crank position sensor or even see it... so how is it changed and whats the location exactly so i know and whats the size of the bolts that hold it in? diagrams would be helpfull.

 

It is right behind the passenger side head. It uses cap screws to hold it in. I think a 1/4" allen wrench works to get the bolts out. You may be able to back them out from the engine compartment rather than from underneath the truck. It is a PITA but doable.

 

I hear all these stories about what a PITA this is but mine was real simple. I just laid under the truck it is behind the passenger side head sandwiched between the tranny and engine. Mine has 2 1/2 bolts holding it in.

 

+1 on it not being very difficult to change. im a smaller guy so reaching up there was cake work

 

Just replaced mine, tape a 1/4 allen biut into a socket that will fit (1/4" drive), and put some extentions on it. Bolts were easy to get out this method, hands too big to reach in there and you can tap the long apaeratis on with a hammer needbe to get rust, etc out. OEM sensor works best for this, I got a BWD from advanced and it got taken out by the flywheel on the first crank, beware.

 

well after talking to a tech for a bit i went and had the codes read.. cylinder 5 missfire wich i figured then i got 2 o2 codes right away before the missfire.. so i went to get another one to put in but its frozen in their by rust a crap so now i got to figure out how to get it out. worst of all the top portion twisted right out and took the wires with it... so now i need to figure a sure way to get it out.
