The issue isn't that the sensor can't read it, if you go into actual values the MAP sensor can read the boost just fine. I know this for a fact because I have personally done it on my car since I don't run a boost gauge on my SC setup.

The issue is that the car is NA from the factory, the computer is programmed to think any positive pressure is the sensor reading something incorrectly, hence the fault.

How do you change the values on the map sensor then? I'm interested

What you are saying about changing values has been denounced by GTM.

There is conflicting info floating around.

Is your tuner an uprev pro tuner?

What values did they change and how?

Huh? Where have I stated you could change any values in the ECU? Directly in THIS thread GTM came on here and stated that you CAN'T change the values for the MAP, which I then restated in a different way

Again, I have only agreed with GTM in this thread. I haven't said anything conflicting in the slightest.

If you're running 10 PSI of boost the MAP sensor is going to read 10 PSI of boost with or without the fault code disabled and is going to report that to the ECU.

Your post made it seem like you were able to change the values.

I also meant in general there is conflicting info.

I apologize if I was unclear, was simply trying to state that this is a function of the ECU and not an error that can be fixed by replacing the MAP sensor with an aftermarket unit.

Well I bought one (GTR map Sensor) and I am going to test the theory.

I have the accompanying p006a code that is also driving me insane.

I dont like having to disable the code.

Do you have access to an OBD2 scan tool that can see actual values? Go into the ECU and read off what the factory MAP sensor is reading at WOT at sat 3500RPM, do the same once you get the GTR MAP sensor in and report back here. I'm pretty positive they will say the exact same thing but it would be nice to see proof one way or the other.

sounds like a plan.

Watching this with interest.... just had a CEL in my car and I am not even running a CAI setup:

http://www.the370z.com/engine-drivet...ml#post2147871

what was the outcome?

is the R35 part number identical to the MAP sensor used in the 370z? if so, then the readings will be identical. If they are different, then i'd say the readings would be different due to sensor scaling.

from memory, the MAP sensor used in the R35 and Z34 are identical. You will also find that the MAP-T sensor used in the MR16 turbo engine has identical MAP scaling. That's the key component in the Gotboost plug and play speed density kit for R35. When i was considering options for relocating the IAT sensor (hence my interest in the MAP-T sensor, to get air temp readings as close to the cylinders as possible), it was the prime candidate. Cost is what canned that idea. Second reason was the potential for heatsoak, which is what i was trying to reduce.

Hmm... I guess none of this stuff applies to a 2009 370z because I have not disabled any MAP DTCs, nor are there any MAP DTCs available in my UpRev, nor have I ever had a MAP related DTC pop up in 3 years of being turbo.

I wonder what inspired them to add this DTC later.

all 370z has a MAP sensor and another pressure sensor near your master cyl for the brake booster to ensure it has constant sufficient vacuum.

there has to be a DTC for each sensor. try disconnecting the sensor in the upper right quarter of the intake collector and then scan the car

I know of the MAP sensor being there as well as the brake booster pressure sensor.

I am just saying that my 2009 does not have a DTC P0106 or any other DTC that occurs as a result of going into boost.
