17090 Transmission range fault sensor
 

Hi everyone
I've got the PRNDS lights flashing, after scanning on vcds it brought up the fault 17090 Transmission range sensor (f125) p0706 -000 implausible signal.
But of background on the car. It drives absolutely fine in all gears doesn't stutter or anything just the lights flashing. Cleared the fault but it reappeared, any idea of what the issue is?
