P1570

P1570 fault code tends to be interpreted as something to do with the immobiliser but I've had it a couple of times as a result of an intermittent throttle sensor. This has been reported several times in the past and it is quite common. The symptoms are sudden loss of power with the revs settling at just under 1200 or thereabouts. This does make it possible to continue at up to 30mph but simply switching off and on resets it. However, on mine the fault recurred within a few hundred yards and seemed to be when the throttle was increased slowly from minimum so, if stuck, a short jab might get past the problem until it can be fixed. in my case the assembly was removed - 3 hex screws, and the top plate removed to reveal the control tracks. a quick wipe with a clean cloth and reassembly gave 2 years use until today. 

Note, the cover is fitted and held in position presumably set in manufacture so it is important to make sure than the screw marks are used to check that it goes back in the same position. Also, inside there are 4 sets of sprung contacts which can be damaged so some care is necessary with the cleaning.

As far as I can determine the clue is the revs settling at about 1150rpm.
