Erratic MAP data

[bertman7807]

Hi there. Ive been having an issue where the car stalls out and I get the gear symbol. I get codes P2227, P0108, P0238 and P0193. I changed the MAP sensor and it only helped for a few dozen miles. I ran a data stream and got a very erratic graph for the sensor. Could this be a wiring issue or what should I check next?

Just a follow up for anyone interested. I took it to our Nissan dealer here. They work on everything and are really good people in the shop. Was SHOwn today (sorry) a faulty wire in my harness. He said I was losing my 5volt signal which caused 3 sensors to throw codes. Should be ready to go Monday. Just passing it along. I have been helped many times here.

Thank you for following up - this is pretty specific, but I will say this, watch out for rodents, they cause a lot of wiring problems.
