hi, bought a range rover sport 2005 last week and it wont go over 2000 rpm, got it checked out and they told me its some fuel pressure sensor p0191 was the code can anyone tell me what part number it is as i cant find any on internet thanks.
mods-can you move it to proper section if its in wrong one thanks

Can you fill in your profile so we know what engine you have?

Was it a private sale? If bought from a dealer then they have to fix it at their cost.

That code is just a generic code. You need to have the fault codes read with a land rover specific tool and it will have two more digits to specify exactly what the fault is.

With just the generic code all you know is there might be a problem with the fuel pressure or it could just be the sensor.

Find yourself a good local Land Rover independent specialist with the correct diagnostic tool and start from there. 2008 MY Java Black TDV8 HSE

Ok thanks
Its tdv6 2.7 engine

Low fuel pressure can be caused by restricted fuel flow, or a weak pump

Start with an OEM fuel filter. Cheapest and easiest place to start

Thanks ill try that tomorrow

update: ok so got it fixed, it was a dodgy performence box off ebay, unplugged it and working fine now.
notice 3 more faults
1- parking sensors are not working always beeping in reverse
2- cigarette sockets are not working, cant find fuse box to check fuse.
3- cruise control not working or maybe i dont know how to turn it on? help
thanks

Sorry to reply to such an old thread but this turned out to be very helpful my Range Rover wouldn’t go over 20mph and had every fault code under the son stored , turned out to be a cheap tuning box that a previous owner must have fitted , removed and it’s perfect again.
