X type error code P0341 and P0346

Recommended Posts

Hi there

I wonder whether someone can advise me. My X type (petrol) year 2004 automatic could not start. Sent it to a garage. The following checks were carried out:-

- ignition, fuel, battery, starter, spark plugs, voltage across the camshaft position sensors (bank 1 & 2). All ok. Error codes P0341 & P0346 registered. Was advised that it is due to the mis-timing of the cam shafts and the ECU detected a range or performance problem with the cam shaft signal. It would be a major repair costing more than a thousand pounds! Please help before I decide to sell it as scrap. Current total mileage is circa 97k. I love this Jag. It will be a shame to lose it like that. Please help.

P0341 is bank 1 camshaft sensor. P0346 is not a fault code. P0346 just means it has found a fault which is p0341.

Anyhow £1000 is ridiculous. Don't scrap your car!

 

Firstly you need to purchase a new cam shaft sensor (2nd hand if you prefer).  Up to £40 brand new.

A bad spark plug(s) can give the same code. If your up for it i would replace all 6 plugs. You will need 6 new up inlet manifold gaskets, they are roughly £40 for 6. You can get cheaper. 6 plugs are £25. 

 

So thats £105 on parts. Eurocarparts always have a online discount code. Or try ebay. 

 

For any mechanic its no more than 1.5 hours work. Again thats about £130 for labour max. 

 

If you went all in with a garage and let them supply parts i would expect it to be £300 in total, maybe less.

 

Shop around but don't scrap the car.

Hi Mike

Thank you for your advice. Finally the mechanic found that there was no fuel into the combustion chamber and therefore could not start. All other error codes have been cleared. Fuel pump is the suspect now but replacement of new pump will cost circa £365 with labour at £160. I am getting another garage to review it. I am going bonkers now. Awaiting dianogsis. My view is that the fuel pump is a simple device like a mini submersible pump and very unlikely to cause problem. Is there some kind of enertia switch along the fuel supply? Meantime I will hold onto my horses I mean my jag before calling it a day for her.

Fuel pump can be accessed by removing the back seat. Some models may need a square cut out. You mentioned in your first post that the fuel amongst other checks were ok. Are you sure your garage is not trying to pull a fast one and get as much out of you as possible. Does not make sense as the code indicates bank 1 cam shaft sensor faulty.

I was told the fuel was ok initially. I have not instructed any fuel pump replacement yet. Not paying for work on a hit and miss approach at my expense. I have another garage to review the problem. It may still be due to P0341. Fingers crossed!!

May i suggest buying your own OBD reader. There less than £20 on amazon. You could check yourself if the fault exists. Very easy to do as you plug it in under the driver side footwell (youtube can show 

 

I once had a mobile mechanic who specialised in making cars overheat. Its only when he worked on my third car that i realised it was intentional.

Hi Mike

The second garage that I went to has advised that it is the timing chain. Repairs would be too costly. I am afraid it is the end of the road for my jag. It is heart wrenching. See photos.

I would get another opinion. The engines are pretty solid. Unless the servicing was not done correctly. Sometimes repairing can be cheaper than buying another car.

Hi Mike

Thanks for your advice. Anyway I have sold it to a scape yard who may try to save it, otherwise it would be crushed for recycling. Good luck to them. It was heart wrenching for me and my wife. I am looking for a S type but not many around with low mileage.
