Hello, my name is \*\*\*\*\* \*\*\*\*\* I'm sorry your having problems with this vehicle so I'll try to help you with this issue.The website may prompt if you want a call, but that would be up to you. The [engine](/topics-engine-ford/) will likely not start at all with the cranksensor removed. And give me a min. as I look up the codes to see what the procedure to check them.

Is this my crankshaft position sensor?
Automotive Expert
so those codes are for cam sensors.

Crankshaft position sensor and [camshaft](/topics-camshaft-ford/) position sensor r the same?P0340, P0345 Crankshaft position sensor codes
Automotive Expert
no they may look the same and sometimes they can be but not always the same. so hold on for the next pic,
Automotive Expert
here it is.

I only have one crankshaft position sensor
Automotive Expert
yes and 2 cam sensors.

that's my camshaft position sensor the picture I sent uIn the picture you sent me it's only shows one crankshaft position sensor
Automotive Expert
No I believe that was a cranck sensor but the pic. was not a big enough screen for me to be certain. and here is a test procedure for those codes.
Automotive Expert
the cranck sensor should be just to the right of the [ac compressor](/topics-ac-compressor-ford/).

I can see it is but where's the second one located
Automotive Expert
the other ones are in the front of each head.

Those are camshaft position sensor in front of each head which the valve cover sits on
Automotive Expert
one on the left is up obove the ac compressor the other is above the [power steering](/topics-power-steering/) pump and yes those are the cam sensors .

I would I have to jus buy one crankshaft position sensor
Automotive Expert
you don't need a crank sensor those codes are not for the crank they are for the cam sensors.
