There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

I put one in for a friend yesterday, It's a tight fit to get at it. 8mm open end-box end wrench, had to use both ends.

12-2-21 UPDATE, Just located 1 sensor in Canada that will be the spare.
Going to be a trick to get it into the US
Canadian Can Am dealers cant ship into the US
WSM 004-520 Is the after market sensor that will work, But you will have to install yourself.

Any news?
Just curious if there are any updates about the 'Camshaft Sensor'.
Anyone have more information about the sensor's?
Thanks in advance. .....:dontknow:

Maybe PMK could offer some more information on the aftermarket alternative???

I have no specifics on what others have used. Suggest those needing replacements research for more info on FB.
Seems these failures are becoming more common on certain year machines.

I ordered one from cheap cycle parts just now for a friend, hope someone can instruct how to install.

I may be all wet on this, but it might be possible that failures being heard of/experienced are the result of individual production lot manufacturing problems. As with the DESS module which allegedly couldn't be tested on the production line, the same may apply to the CAPS. The DESS one could more easily see because that unit is tied to an individual chipped key; however, with the CAPS, adding a testing system to the sensor production line when the production specs for it have already been established might have added a cost that Rotax/BRP was unwilling to accept.

Just got an email from cheapcycleparts.com, the sensor is on back order/expected 01/31/2022

What year and model is this Spyder?
How many miles are on the Spyder?
Just trying to get the full information.
So moving forward, I would have a better
understanding of when I might have a
possible problem. ..:banghead:
I hope that this is not a normal.
Time will tell. ..:thumbup:

Myself, avoiding speculation and rumors will let you chase your idea down that rabbit hole.
All the best with it.
I will speculate that this not not a BRP or Rotax manufactured component, more likely it is made by Bosch and they are at fault. Similar to how auto manufacturers got drug in by Takata airbags.

Back to the original question re potential repair:
There are optical (such as Martek 440 used to replace dual points on my 1976 Honda CB750F) no longer common, hall-effect and magnetic coil sensors (also know as variable reluctance or magnetic pulse generators) for cam and crank position applications.
On Sportsters, the 2 wire magnetic is the most durable but not as clean a signal as the 3 wire hall-effect on Dynas.
Potential for failure is all related to heat (most are rated -40F to 300 F), which affects potting compound, coil insulation and properties of a permanent magnet.
It would be extremely difficult to remove potting compound, rewire a coil and/or replace a permanent magnet.
Just my 2 cents

Regarding JayBros suggestion about testing: The automation company that I retired from designed and built many automotive sensor production lines, both engine and brake sensors. All were tested, some not only ambient at also cold and hot. But proper resistance readings at the time of manufacture do not guarantee durability of cps or cpk sensors. That will be affected by the quality of the potting compound, the quality and thickness of the magnet wire insulation which is typically varnish and the quality of the permanent magnet.
Also affecting the sensor life is the maximum temperature of the sensor mounting location.

My Cam Postion Sensor was throwing codes all over the place and then I noticed some oil residue around the unit. Before tackling the job of pulling the pulley wheel for access to the CPS I doused the switch with brake cleaner. It has worked perfectly ever since. It's worth a try ! Just sayin' --------

Just a note here, The Cam Position sensor is on the side behind the oil filter, Not on the belt pulley side.
It looks like there maybe a blow-by issue from the crankcase and not oil from the filter change.
Update. sensor found at a Canadian dealer in previous post above , was delivered to MN today, cost was $90 delivered

My thanks to T.P. for alerting me to my error! I mentioned spraying the "cam position sensor" when in fact I meant to say "the gear position [angle] sensor"! I hope my "Geezer" slip didn't send anyone off on a wild goose chase by pulling off their drive pulley's! OK --- Time to go take my medication!! Cheers!! Bob
