Hi all,
I have a strange and ongoing issue with my freelander 2 (2007 2.2 auto) which I am wondering if anyone else has encountered and solved?
It starts off as a shuddering at around 2000 to 2500 RPM a bit like going over a cattle grid. Once you are not at this sweet (or not so sweet!) spot then it goes away. However in time the crank shaft sensor totally dies. It started stalling out july 2019, with a crank shaft sensor error.. so in went a new one which died totally in August (leaving me and caravan closing the road out of Salisbury!). New sensor in again. more juddering Since April this year. replaced sensor, this time juddering didn't go away. serious juddering this week on the way to holiday with the caravan and then crank shaft sensor death again. New sensor put in again 2 days back (luckily by now I carry a spare!). Running again but with lots of juddering!
So what might kill crankshaft sensors and cause juddering I wonder.
I also wonder if it is related to the new timing/trigger wheel and crankshaft pulley we fitted a couple of years back when changing the cam belt. That was an odd one as the '07 car had a thicker trigger wheel and thinner crank pulley than later models. The only ones available now are with a really thin trigger wheel and a thicker pulley. So we had to swap both the trigger wheel and the pulley. Perhaps it is now slightly misaligned. It isn't possible it seems to source the exact ones.
My only other thought would be the wiring to the sensor. I am off out now to resistance test the wires back to the ecu. Also to volt meter the supply to the sensor (I think it is 3 wire with one sense, and 2 supply wires).
I tested it last year ago though and it was ok (but the symptom had gone then).
total nightmare!
