Hi

My 1996 Jaguar XK8 suddenly wouldn't start today, I've done a scan and the code is P1336 Crankshaft Camshaft Sensor , Has anyone had this issue before and was it it easy to repair ?

Thanks

Had to get recovery to take the car to the local garage, they say if its the timing chain then i should throw my car away. hopefully not as i like my xk8 and spent lots of money on it.

fingers crossed its just the sensor

 

If your car was running and when you parked it and came out to start it wouldn't start. I would highly doubt you had a timing change failure. Code 1336 encompasses both the crank and cam position sensor. I would first go for the crankshaft position sensor as being bad. When running and the sensor goes bad the ECU is supposed to default to the cam sensor for operation signal. Keep you from getting stranded. Neither sensor is expensive nor difficult to get to for changing.
If you are concerned about timing chain Have them do a compression check. Bad chain and you will find low cylinder readings.

 

Hoping its one of these sensors , when the car was taken in the recovery guy thought it could be bore wash from the sound of the car when trying to fire it up.
maybe this is from the battery wearing down whilst this has all been happening.

 

Update.

My local garage has done a Compression test and said the cylinders are not giving enough compression, so its looking like a new engine. Has anyone had an engine fail like this ?

 

Did they check the timing. Was the compression low one one bank or both banks. If one bank was low I would suspect a bad tensioner.
It doesn't sound right to me that you car was running fine and then on next start up you have low compression. I think something failed and my best bet would be tensioner. What I understend they fail more often during cold start up.

 

If it's low compression on all cylinders I would suspect bore wash from trying to start with a failed crankshaft/camshaft sensor.

Also, if that's the situation you need another shop as the one you have is not well informed and too anxious to charge you for an engine replacement.

 

After calling Surrey Jaguar they said the engine is very likely to be flooded and I have bore wash. They think 99% sure to be this

Does this situation sound familiar to anyone ? If my local can't fix it I'm off to Surrey Jag centre for another opinion

 

I was thinking on the same lines RJ. He said they mentioned bore wash. I would assume they did try to put a little oil in each cylinder when they did the compression test. If they didn't I would get that car out of there.

He also mentioned that they suspected timing chain and thay said if it was that he should" throw away the car". You can have a tensioner go bad and not loose the engine.
I think you need to ask them a few questions.
Did you put oil in each cylinder to eliminate bore wash?
Did the compression increase after adding oil in cylinders?
Did they check the engine timing?

You need a little more diagnosis before you even think about replacing the engine.

If they didn't to a complete diagnosis before telling you need a new engine I would seriously think about changing shops.

What is the mileage on the engine?

Best of luck

 

I made my last post at the same time you made yours.
Put a teaspoon of oil in each cylinder. If it is bore wash it should fire up.

 

+1
The last thing they should have done if they had a suspicion of tensioner failure would be to try to start the car.

Take a look at this on Gus' site:
JagRepair.com - Jaguar Repair Information Resource

It explains bore wash and the procedure for recovering from it.


HTH,

edit: Sorry BobRoy - I must learn to type more quickly

 

No apologies needed. Your post was better and you linked to Gus's site. That took 2 minutes longer. And nobody types slower than I do. I peck with one fat finger on a cell phone. I just hope all our info can help this member.

 

After telling the garage about the Bore wash process they did it and my car is now up an running.

luckily im a very determined person otherwise i could have scrapped my car on the first opinion.

 

Great news. Glad it was that simple.

Please do get those secondary tensioners checked unless you're absolutely certain they are the metal type. They can and will kill a motor when they let go. It's not a big job to lift the cam covers - particularly the RHS one.

You'll sleep better.
