Just wanted to see if anyone has the correct voltage readings from a map sensor on a 96 dse , pre egr engine ,
At idle I get 1.8volts - 2.95 volts at 4000rpm . can anyone tell me if thats correct .
There are 3 wires on sensor . 1 is ground the other a 5volt supply or ref voltage and the third the output.
some other sites say that it should give up to 5 volts out at high rpm ?

Thanks for the prompt reply , got a better understanding of that now , in relation to what its measuring .
I dont know what the make up of the sensor is though , I presumed the the 5 volt contstant is a input and a reference voltage .

Hi have id on the cables ok , but im trying to find out what the output voltages are supposed to be for normal conditions , im getting idle at 1.8v. is the correct?

The reason for checking this is re a possible gearbox fault , gearbox supplier suggested that the MAP may be an issue with the late changes on the box ,
When in low range the box changes up quickly but in high it revs to 3800 rpm to get to 2nd and the same for 3rd. the box is not slipping or flaring in the changes.
Fluid and filter changed , old fluid good and no dirt in filter,
Box was perfect until the transfer box was changed a while ago.Im just trying to isolate items before i go down the road of changing the box.
