How would you approach this?
Discussion
Hi Guys, I'd like to run something by you all for your thoughts and any useful ideas on what to do next (without breaking the bank $$$).
My 2017 Jaguar XF x260 petrol 25t started to intermittently display an amber engine management light.
On further investigation with PATHFINDER (see attached photo too) it returned a the following single PCM error "P0017-00 Crankshaft Position - Camshaft Position Correlation Bank 1 Sensor B - No sub type information".
According to TOPIX: If this DTC is reportedwith P0016-00 or as a single DTC, check the base engine timing for at least a one tooth out misalignment between the camshaft and crankshaft and rectify as required.
The following is recommended as resolution: Monitor Description - The powertrain control module has detected incorrectly installed components. Prioritized List of Possible Causes:
? Engine timing chain at least one tooth misalignment between camshaft and crankshaft
? Camshaft position sensor fault
? Crankshaft position sensor fault
? Camshaft actuator failure
What should I do next? Is the proposed misalignment of the teeth the most likely cause? Timing chain (and components) replacement? Please note: I have a petrol engine which I believe is less likely to have an issue with the timing chain?
Kind Regards,
MC

When we get any form of cam/crank correlation faults it usually means timing chain stretch.
Does the car start ok or does it turn over a few times before firing up
Is the oil level correct, has it ever been run low.
Have you cleared the code and then given it a run then scanned it again

Hi stevemcs,Does the car start ok or does it turn over a few times before firing up

Car has had annual dealership services from new
Oil level fine
No issues, starts fine but maybe runs a little lumpy
Only done 30k
Cleared codes and returned straight away although amber engine light isn't currently on
I would get the light extinguished and get rid as soon as possible . Its not the first time you have been on here about issues and fearing it won't be the last this is why I offer this advice . I appreciate you may not be in a financial position to do this immediately but its what I would be looking to do at my earliest possible convenience .

What about clearing the codes, ignition off, ignition on, then scan but don’t start the car - if it comes back on without the engine being started then it points towards electrical rather than mechanical
Thank you for this suggestion, I'll try this ASAP.You sound very knowledgeable, has this worked/confirmed things for you in the past?
A few points:
The fact that the error code returns immediately after being cleared is a significant point.
The code suggests a possible misalignment of at least one tooth between the camshaft and crankshaft. This could be due to a timing chain stretch, which is not uncommon and can happen even with a relatively low mileage like 30k. Despite the vehicle having a petrol engine, which is generally less prone to timing chain issues compared to diesel engines, it's not immune to this problem.
The suggestion by "stevemcs" to clear the codes, then turn the ignition on but not start the car is a good diagnostic step.

Thank you Paddy. I wonder if I swap sensors over and if the fault error appears on bank 1 sensor A that would also indicate sensor fault?The fact that the error code returns immediately after being cleared is a significant point.

If I do need to replace my camshaft sensor would this be the correct replacement?

Is the following diagram showing the front of the engine and if so which one/side is Bank 1 Sensor B please?
stevemcs said:
Disconnect it but do not start, scan and it should say something like open circuit.Make sure the part numbers are identical before swapping them over. Correlations usually are mechanical
Thanks stevemcs.Do you know which sensor is A and B please? I'm assuming A left, B right as you look at the engine?
Car was scanned this morning and I can confirm (for now at least) that the single P0017-00 error code has cleared. Started and ran the engine for a few mins to be sure and the code didn't reappear.
Reminder: I replaced both camshaft sensors with these https://www.ebay.co.uk/itm/334753139386?epid=24923...

Yes it is the right thing to do.
I do a lot of work at a Jaguar specialist and although the chains on the 2.0d's seem to be incredibly common it is not unheard of for the petrol's to suffer too. It also doesn't seem to be mileage related either......just a fundamentally poor design!
Good luck!

Good news. Indy found the P0017 error (original one that has come back) along with a couple more which I didn't take the details down unfortunately. But, the additional errors are related to the VVT and the Jaguar TSB instructing dealerships to replace due to a batch of faulty VVT's. Indy has ordered two new VVT's which they will replace on Monday.
They said there was nothing to suggest a timing chain fault (yet!).
