Another srt problem.

Well i had thought i fixed my cars problem as it was throwing a couple differant codes. I replaced the 02 sensor, only to later on get a MAP code thrown at me. P2074, after looking into it a but heavily, i volt tested the bulk head into the map, and had 4.88 volts going in. On the output side it was only reading 1.68v with key on. the bulk head and wires are fine, ive already checked the whole wire setup, the only thing i can figure is the map is gone bad? does this all sound about right?
I have a 3 bar map sensor just not installed, is all i need to do to instal it tune it with a dsp and call it good? or is there something more i would need to purchase?

thanks

Have u tryed measuring the voltage wile having someone rev the motor it should change with air flow if not I would say it's bad just my 2 cents.
