0.3-0.7 vdc or 300-700 milli volts DC = same thing.
it should scan quickly from one to the other if its working - BUT if its just very rich - it will read just over 1 volt (1000 mv) all the time, which was how we come to find it was the MAP sensor ; i'd already changed my lambda as it tested as faulty - but then so did the new one as soon as it was fitted - things started pointing to that it wasnt the lambda after all
so i have to choose to replace either one to find the fault.....such is life.
all i noticed was that when i tried adjusting the CO using the screw, i couldnt get it undereath 3% (on the gas analyser)
and the car isnt using any less fuel than it normally would even with the new closed loop chip fitted
worst case i will have ither a spare lambda or a spare map sensor
