Thread: Disco 4 tdv6 2.7 year 2011 looking for crankshaft sensor location

The sensor is behind the flex plate. You don't need to remove the gearbox. You can access it through a hole in the LH side in front of the bell housing. It's not an easy job but can be done

The mechanic obviously doesn't know Land Rovers. The fault may not be the sensor itself if there are other fault codes and because that sensor rarely fails with fault codes, instead just intermittently stops working which is usually seen as the engine has stopped.
What are all the codes, not just the description from the mechanic's diagnostic device?

First problem was that the old water tank splitted and for the lat 300km i had to stop every 50 and refill. In Darwin I replaced the water tank and sensor and seems ok.
The big issue now is that the car enters in limp mode and lots of system fails after running for 10 minutes. HDC, gear, etc systems all fail and i have to drive slowly and park. I wait 10 minutes and everything works fine again. A mechanic has looked at the trouble code. It seems that he receives the trouble code for crankshaft sensor and other codes after. He has spent hours looking for the sensor. It seems like the position is different depending on the model, year, etc. He has looked everywhere and came back to me saying that It has to be inside the gear box. This means that we would have to remove the gear box to find the sensor inside and change it hoping that it was the one creating the problem. I cant find enough evidence online that the sensor is there and stressed because even if it is, I could not be the original issue. Anyway, I would appreciate if anyone can confirm that the sensor could be in the gear box and whether there are other things to check that could be triggering the limp mode before doing that big job?

Welcome to the Top End!

You obviously did not take it to Darwin Land Rover - 54 Albatross St Winnellie 8948 2352. Leigh is the Land Rover warranty service agent (and an excellent, knowledgeable mechanic) and will be able to assist you.

Sounds very much like a dying high pressure fuel pump symptoms. Could be as simple as a blocked fuel filter though. The codes will help.

I would suggest:
*if it has any sort of duel battery system or any added electrical, i'd disconnect it all, clear the codes and try again.
*ensure the positive cable from the battery to the fuse box is secure, also check both terminal clamps are secure.
*ensure all the fuses and relays are pressed in and not lose.

Hi, thanks for the respond. Well, I actually did go to Land Rover but unfortunately they told me they were very busy and wouldnt even start looking at the car in a month. It was Xmas. I wasnt sure how bad was the problem so i found another mechanic that claimed he was a "Land Rover specialist". Obviously not. Leigh would have definitely be the right person and it would be sorted now. however, i am still stuck without a car. The mechanic i found only just managed to change the sensor. And as some of you predicted, the problem still seems to be there. Apparently he turned the car on once he changed the sensor but 10 minutes after it shut down again and cant turn it o again. He did register the sensor which is:

P0336- 31 crankshaft position sensor a circuit range - performance no signal

To me it seems like the crankshaft sensor again but how can it be? Did he buy a faulty one or is there any reason?

THanks so much everybody. And yes, I have told/threaten the mechanics that i would like to take it to Leigh but the car is half dismantled still and I dont know how Leigh is going to take the mess that we have created on it. Anyway, if anyone has any idea on what might be happening, I would really appreciate.

The sensor is new but, as mentioned, he didn't buy a genuine land rover one. He bought a Borsch one. Do you think this could be a problem? Both, the old sensor and this borsch one have provoked the same reaction. Car turns on, runs for 10 mins and then turns off and it seems we can't turn it on again. To me that means two things: Or both sensors are faulty, or both are ok and there is some other problem. Now that the car is stripped and is not hard to change the sensor , should we buy a genuine land rover one just in case? Anyone knows what is the part code or if there is any specific sensor that is very reliable. It also took us a while ti find out what is the exact model that we need. The brooch we got, looks exactly the same as the old one but wondering whether there is something different. Sorry guys, yeah I'm a total ignorant and this sooo frustrating. And I miss my Land Rover sooo much!!!!
My plan is to solve this genuine/off market sensor situation and ask the mechanics to put everything back in order to send to Leigh at Land Rover. Mechanics is starting to be onboard wth this even that he understands that he probably wouldn't get much money for all the time he is put on it. I dont know what you guys think but, should i pay anything if he s made it all very complicated and i ve been 2 months without car, renting cars, etc. and nothing is solved?
