Is the car boosted? I've only seen that code pop up here on guys with forced induction.

Its all motor and no mods at all... Its just annoying after i changed the MAP sensor and it came back after 3 days with the same error code P0106.,

How's your idle? Lagging or hesitation during acceleration? There's a similar/same sensor for brake booster.

Everthing is normal, no lagging, no rough idle and no lagging.. Its just that stupid SES light and same error code every time i connect my OBD2 reader to reset it.. Im totally lost right now.. Any suggestions or help is highly appreciated

I will tru to clean the sensor your talking about tomorrow by the brake booster, maybe thats the culprit, I got a bottle of the MAF sensor cleaner.. Crossing my fingers!!

which sensor is this? Got a picture of it?

Does your code reader give data? Have you checked to see what the values are in ECM data or did you just see a code and throw a part at the car hoping it would work? You need to see what the baro reads usually in kpa KOEO (key on engine off) and see what the baro is at your see level. Also check it running, not sure if there is a specified value engine running from Nissan but if NA then it should never be a positive value. If it is something that is intermittent then you need to check freeze frame data and see what the value is at the time the code is set, this will give you clues as to if you have a intermittent open or shorted wire possibly bad connector terminals too. You have already changed the sensor and still having an issue, odds are cleaning the new sensor won't do anything for you. Besides never heard of anyone cleaning a MAP sensor with any success it is not like a MAF sensor.

to be honest with you I never check any data or values..i only have the basic code reader from autozone for $50, all it gives me is the code P0106 and check engine light reset and some other stuff..what do you suggest for me to do or what kind of test should i run, by the way im not going to touch or clean my new MAP sensor by the manifold maybe just clean the connections and i will try to clean my other sensor by the brake booster..

If your going to be trying to work on your own car then you really need something better than just that code reader. This is why so many techs hate it when people always think we are ripping them off because don't we just plug the little thingy in and it tells us exactly what's wrong. All the code is doing is saying hey something is wrong here. It does not tell you what is wrong. The map is generally used to determine intinitial fuel trim on start up as it is being used as a baro sensor. You need to see what it's reading vs your baro reading at you sea level (usually in kpa sometime in hg). Odds are you have a intermittent open or short but you need freez frame data to see what map reading is when code set. With this info you can disconnect your map and check data KOEO if it reads same value than tada you now know you have an intermittent connection, if shorted you have a reverse scenario. If you don't have the tools or the ability to understand this then take it in and pay for someone who is qualified to do it and just know you saved yourself money in the long run by paying up front rather than paying later after you've spent a bunch of time on money and exhausted all avenues before finally paying someone do to it.
