Map/boro and absolute pressure sensor question
Does anyone know the ohm readouts for the map/boro sensor and the absolute pressure sensor?
This is for a 1996 Maxima automatic.
I did peel back the sheathing on the wiring for the map/boro sensor. No broken wires and the red one is giving me 5v on the map/boro, 12.5 on the red wire to the absolute pressure sensor. also replaced all the vacuum hoses between the 2 sensors. Still have a slight sputter at 30mph cruising speeds.
I know this topic has been touched on many times and I have looked at many threads about it. Any help would be appreciated.

I have not tried switching them. Local yard has 2 fresh 96' Max's that have both of these sensors but....I'd like to know if there is a ohm rating so I can test before I purchase them.
Scored 3 drop resistors for the auto trans for $4.75/ea. last sunday. Pretty sweet since I got the car fairly cheap. Previous owners sold it because the transmission was going out. Was shifting hard. Replaced the drop resistor and shifts fine now
Will check for vacuum tomorrow.
If anyone has known good ones laying around, do a ohm test for me please!!

Thanks! that should help a lot! BTW: yes I do have vacuum at the MAP...pulled it off a little while ago and its sucking. Even swapped another MAP I got from the yard earlier....same results with an evap code to boot! GAH!
