Yep just had that before christmas on a 3.0 CRD jeep with a Cambiare aftermarket crank angle sensor ..... ex ebay unit that i had to modify with a hacksaw so that it would seat further into the engine block to get a reading.
Now that I have almost killed myself getting the full plug off ��...Oh man, guess I'll see how much the stealership sells them for before I jump into wiring. Thanks!
Another thing that trips up magnetic sensors like that is simply getting a bunch of filings stuck to it. Sometimes you can get them working again by simply cleaning the end off.
So it's been snowing and I haven't got much done but I'm thinking...if I don't have an ABS light on doesn't that mean the abs is getting the speed sensor signal while the PSOM isn't?
I doubt I would worry about changing the odometer. Iowa titles have a check box that just notifies buyers that the odometer reading does not match actual mileage, not sure on yours.
