1995 XJS camshaft position sensor
Has anyone had any luck finding a rebuild kit or remanufactured camshaft position sensor for AJ16 engine.
I am aware that this particular one was only used on the 1995-1996 xjs and the 1995-1997 xj6
After researching, it appears the rebuild kits are no longer supported.
Maybe someone on this forum has used a rebuild kit from another make.
I am hesitant to purchase a used one although that may be my last resort.
For those that may question why I need this part, I have spark, fuel, rpm’s show when cranking. After about 20 seconds of cranking, the engine does start.
Thank you

I have one in my parts bin that doesn't have a DAC number on it.
The length is about 18 inches and the connector is the same as a fuel injector.
Is there a test I can do to see if it is still viable?
$10 plus $10 for shipping.

Givoo,
Whilst it COULD be the engine position sensor causing your problem, I wouldn't condemn it just yet.
Is it always 20seconds before it catches? If so, I'm not sure it's the position sensor. Even without the sensor working at all, I would expect that the engine catches at different times as it tries to guess when No.1 cylinder is at TDC on compression stroke.
Also, does it vary depending whether it's cold or hot? Does it vary if you cycle the ignition a few times to run the fuel pump repeatedly before trying to crank it? It could be a drop in fuel pressure in the rail, either through a failing pressure regulator or fuel vapourisation when hot.
If you try out a few different approaches and tests, you may pin down whether it's a fuel issue rather than an ignition timing issue.
Good luck
Paul.

i also disconnect the lead from the camshaft sensor and there was no change.

Paul…thank you for your input.. I have run down all the tests. It’s the same whether hot or cold. Plenty of fuel pressure. The car until 5 days ago started within then first 2 or 3 seconds whether hot or cold.

Givoo,
had the exact same issue several years ago. It was the cam position sensor….not the entire unit that you showed but the plate w/sensor inside the distributor looking unit.
Grant Francis sent me the procedure on replacing this portion and how to reposition the unit.
I had purchase a used unit for less than $100 and removed the part I required.
I saw the plates for sale on eBay and used unit on Amazon for just over $100.
Good Luck

Softball60/Paul,
Exactly. That is the plan if I can get a used unit. Do you by any chance have the procedure from Grant Francis?
I have gone the Cardone reman route with no success. I spoke to their manager and it
seems they no longer have the necessary electronics.
I spoke to Standard products and their part SP666 has been discontinued.
I thought I had purchased a week ago a used unit from a site which showed it had one, but
today the owner emailed me to inform me
he doesn’t have the sensor.
Because I didn’t hear from the seller, I purchased another one
on Thursday from a eBay seller and I am awaiting
a response for shipment from the seller.
I did see the internals listed on eBay for $399.99 Walker part number 235-1693. If all else fails, I will bite the bullet.

Recieved two used camshaft position sensors yesterday.
Installed a used camshaft position sensor today and all is now good.. No problem starting
I now have an extra good used camshaft postion sensor if any one needs one at $120.00 USD.

Since I was just doing a replacement, I took the liberty of getting the dot close to top dead center ( in plastic window) before removing by cranking engine over. I then removed and put the replacement sensor in and with the dot at the same position. Easy and fast. I took before and after pics verifying the position of the dot in the window.
But I will use the procedure to verify TDC and and check my fitting at a later date.. Again thank you
