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: ... 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 ... 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 ? |
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!

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.

Hey cool...
Anyone ever told you that "you kinda funny"? |

Just wondering what is CKPS ?
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!

Official Jaguar Repair Manual (no, not Haynes manual). Electrical Diagnostics Manual - XJ6-XJ12 (Cover 1) Section 1, Page 5 Terms Crankshaft Position Sensor Abbreviation (if avail) CKPS Definition generates crankshaft position information in conjunction with the CKPTR (also generates speed information in certain applications) |
