The all-too-familiar -stalled and P0727 code- CKPS adjustment?
So today, on the way home, I got stuck on the freeway in 5mph creepy crawly traffic - I could literally see my exit lane about 1/4 mile away, when the car died.
Pulled over and attempted to start it ... crank crank crank - no fire.
Then I saw I had my code reader in the back seat, so plugged it up ... P0727 thrown. I did a quick Google search while sitting there, contemplating my fate - having to call a wrecker to tow me 1 1/2 miles to the house.
Then I thought, "let's clear the code and try again" (after having sat about 10 minutes). Clear the code and she fired right up and she brought me home without a miss.
I found this in a past post on the subject:
So, I've read if you crank the car up and the tach doesn't move, this a sign that the crank-position-sensor is going out. I tried it ... crank crank crank, no sign of movement with the tach, but then the tach jumped up and the car fired up like nothing was amiss.
I sprayed the sensor at the crank ring with electronics cleaner, to include disconnecting the plug and spraying it too ... she fires right up now (she's been cooled down for at least an hour+).
So anyway, back to the quote ... I dont see any sort of adjustment for the gap for the CKPS ... I have removed it to take off the damper (about 3-4 months ago), and dont remember any sort of adjustment. I measured it with a flat-blade gap gauge and it's about .040".
Any thoughts ?

... Crank shaft sensor gap between sensor crankshaft on mine was greater than .047 adjusted spacing to .025 solved my issue with ckps . Even bought a new sensor didn't help till i adjusted spacing ...

There are some reports of electrical connector plug corrosion at the ecu causing this code- due to water ingress from the sunroof drains. Or, you might just have a failing CKPS- the ecu doesn't know a bad gap from a failed coil, I am sure!

Maybe Ross knows something I don't, but I'll fall for it.
CKPS = Crankshaft Position Sensor - to differentiate it from:
CPS = Camshaft Position Sensor

Mr. Cool continues to ask this question even though he has been told. He is apparently trying to make some foolish point that it does not appear on his list of "known acronyms". I would say his "known acronyms" is unknown!

Caldercay, many thanks, appreciate it, and to you sparkenzap the know it all, as if you knew why i ask, if you can't help just shut up, your sarcastic remarks are never appreciated.

Mr know it all show me the sequence and the portion where i was already told except for the answer from caldercay. sparkensap your kind do not deserve to be here in a jaguar forum. your superiority complex is tripping your ego.

remind and show me when and where was i told before you pass judgement. your such a sarcastic pampas pain in the behind. your pretentious to know it all won't answer my inquiry best for you to just shut up.
