Question about Saturn SL2
Yes it has a sensor and they are color coded however I don't think it's called a maf or map sensor that’s a GM name, there would be three wires on it on ground one 5 volts reference and one for connection to the computer to tell the computer how much air flow there is, and the reading would be from 1.5 volts to 4 volts.

All wires on the sensor go to the computer, one will be a standard power wire going to the sensor, and the other 2/3 will be resisted signals going from the sensor to the computer
