Can someone provide the voltage values for checking a MAP sensor? Green wire to ground it reads 1.0 volts koeo and the same at engine idle. At 2500 RPM the voltage increases to 1.5.

I can not find any tables in my Haynes manual that depicts what is an acceptable voltage range.

The Haynes manual for our Saturn (sorry) indicates that 3.8 to 5.5 volts koeo and 2.3 volts less with 10" of vacuum applied. Simple enough.

Thanks for any help.
