There isn't one. The crank sensor you'll want some universals and different length extensions. A small mirror to see back there will help also. It's a PITA. As far as the Cam sensor goes, that is a matter of removing the distributor cap and rotor. If you've done that, then you know thats a pita too.

cam sensor replacement starts on page 8I-7, crank sensor R&R starts on page 14-39. Why they aren't both in the ignition section is beyond me......

Just to be clear, I was referring to a DIY in the FAQ section.

Well I changed out the crank sensor yesterday, not all that successfully.

That crank sensor is a pain in the **** to get at.

My wrist is all slashed up from the heat shield. It was tuff to get my hands in there, I was really working blind.

Anyway, changed the sensor out and now it throws a P1391 code, 'Interim loss of CKP'?

Doesn't run well at all.

I am going to go back in and make sure it's in the grommet hole correctly, I can't see in there only by feel, or swap back to the original.

Yea sucks. Sounds like it crooked or not in all the way for sure. Make sure you plugged the connector in all the way too.

What a bitch, I removed it blew out the hole, electric greased the connector and re installed yesterday. Took me half the time now that I know how to get in there.

Test drive was good, but when I went to run a few errands, it threw the code and ran like crap again right away.

I am going back to the original sensor, today after work, seems the PCM has no problem seeing the signal and throwing a code if it doesn't like what it sees. I am going to have to assume this sensor is not the source of the mysterious die while driving issue I am trying to solve.

I'll wait for my new PCM to arrive this week and try that.

A fair bit of the time, the PCM doesn't like aftermarket sensors.... especially in critical locations.

That could be it, this is an aftermarket sensor, and it was about 40% less than the dealer, but hey it says right on the box 'NASCAR performance', so it's gotta be good...
