Default crankshaft position sensor issues

Hey guys. Ive been getting a recurring engine code saying my Crankshaft Position Sensor is faulty. After reading about it, I can tell that its basically located on the left side of the engine under the main crank pulley. Would getting to it be just a matter of taking off the left tire? Or do I need to do this from inside of the engine bay? Im thinking it might just be covered in oil/dirt, so I want to check it and disconnect it before buying a new one. Any tips on this?

you have to remove the crank pulley and belt covers to get to it. if you have all your belt covers, i doubt it is covered in oil or dirt. though you should check to see if the wires are rubbing against the alternator belt (people forget to clip it back on to the bracket)

Ok, so what are some things I should look for on it before ordering a new one. Its not exactly cheap so if mine is still good I want to hold onto it. Im guessing I should just look for any electric connector issues such as corrosion? If theres nothing visibly wrong with it should I just assume its "Dead"?

what usually happens is the wires get rubbed against the alt belt or the wires can get pinched, this is what happened to mine, i thaught it was bad and got a new one then saw the wires were cut by the alt belt, any ways its a lil work to get to it but if its visually looks good then it might be dead but i havent heard of them dying ever. I have like 3 laying around so if you need one lmk ill sell one for hella cheap for you and they are in working cond.

That's not the crankshaft position sensor its the crankshaft fluctuation sensor. The crankshaft position sensor is inside the distributor and if its bad you'll need to replace your distributor. What is the code exactly?

ckp=crank position sensor
cfp=crank fluctuation sensor

aren't you glad you didn't go tearing into the cfp?

I forgot the exact code but I am 100% sure that the code was for the POSITION sensor... not fluctuation. I have read in various places though that the crank position sensor is located under the main crank pulley... I've even had someone point it out on a b18 that was out of a car. Could it be that I was looking for a fluctuation sensor the whole time?

the fluctuation sensor is located behind the crank pulley, as stated.
crank position sensor is located in the distributor.
you'd better pull the code before making any repairs

I cant seem to open that link. Here are a bunch of links that all seem to point to it being in one of 3 places, none of which are the distributor:

http://en.wikipedia.org/wiki/Crank_sensor
http://www.ehow.com/facts_7711805_cr...on-sensor.html
http://www.webanswers.com/automobile...ocation-155b40

Everything I searched seemed to point to the engine block near the crank pulley/flywheel. If it is in the distributor like youre saying, why do I have to replace the entire distributor? Thanks again for the help

Are you obd1? If you are, you don't have a fluctuation sensor

I think the crank fluctuation sensor is attached to the oil pump? Google obd2 pumps

You could replace the crank position sensor inside the dizzy, but you can't buy the sensors alone. You would have to buy a new distributor and either use it, or swap the internals

You still haven't given us the exact code. Make sure what it is before you waste your own time

Well its a 1997 LS, so its OBD2. I have found multiple sites that sell the sensor alone so Im getting very confused now:

http://www.drivewire.com/vehicle/acu...W4b7a599a692e4

I will pull the code and post it as soon as I can. I am just getting so much conflicting information. The guy a few posts up even offered to sell me the Crank Position Sensor, so they must be available by themselves without an entirely new distributor.

none of those links are of any use. all they do is explain what a crank sensor is. they aren't specific to your vehicle.
the divewire link is showing a crank fluctuation sensor. whether it's labelled as such or not.
here's another pic of the ckf (crank fluctuation) in this link

Like Jason said, thats a Crank Fluctuation sensor.

Anyone who tells you 'they sell crank position sensors individually' is confused by a crank fluctuation sensor.

Get the code first, and ignore what you read. Lots of people are mis-informed.

^ Wow I cant believe Beck Arnley is mis-informed as well. Lots of people are.

Get the code! You better hope its the crank fluctuation sensor, since it is cheap and easy to replace. The Crank position sensor requires rebuilding or replacing the dizzy.

best of luck!

not that easy to replace. basically a t-belt job.
and they're calling it a crank sensor because it still is a hall effect sensor which detects abnormal movement of the crank. fluctuation. detects misfires for the most part. the crank position sensor is more to allow the pcm to know whether the crank is rotating or not.
it really depends on the exact code you're throwing

doesn't matter. where's the cfp then?
why on the distributor pin out is there an output v and ground for ckp?

tell you what, if i get a ckp code, i'm not probing or replacing the cfp

Because its not and they're wrong I guess. Not sure why we're even discussing this anymore, here's photos from the 96-00 shop manual from Honda, they call it CKF or crank fluctuation sensor. Now op pull the code and list it here and stop guessing.

CPK is located inside the dizzy. Your car will shut off occasionally at first and then it will shut off after a couple of minutes of running if you dont take care of that. You basically need a new dizzy. Check the o-ring inside the dizzy and make sure oil is not getting in there too.

Actually the CKF is cheaper than buying a new dizzy.
