well ok i bought an escort mk3 rs turbo repair book

my NTC engine temperature sensor is good they say it must have betwenn 1300-3600 ohm at COLD engine ok my have 2380 ohm Cold engine

my auxiliary air device works



my pressure accutator (black box on the metering unit near the wing ) is ok they say it must be betwen 16...21 ohm my have 19,4 ohm and i have 8 volt when contact is on

my throttle postion is good but only at full open i have 6,9 ohm an not betwenn 0....1ohm
strange but it s not because that the engine won t start

then i make some test like they say in the book

i took the yellow plug for the engine temperatur sensor off it makes like the car is cold -30 degree
but then at the wiring to the pressure accutator (black box on the metering unit near the wing ) i have 019.5 ohm whitout contact an d then when i put contact i have nothing???
if i do a bridge on the yellow plug (engeine temperatur) i have ohm 024.6 with contact and again 019.5 ohm without contact ??

and also my other pontiometer on the metering unit gearbox side i have volt on the plug but then when i do the test to put the multimeter plus pole in the middel pin on the plug and the negative to the earth i have 1,800volt and it do like a countdown ?? and when i took the air flap down nothing change
