RE: Sensor return Voltage drop testing ?
e.g. A typical MAP sensor's output may range from 0.5 volt to 4.95 volt, referenced to its ground pin, so a 0.1 volt ground shift will give an apparent MAP minimum output of 0.6 volt and will be interpreted by the ECU as such.
At the top end, it depends on whether the sensor supply is a stabilised 5v or 12v.
