MAP Senor on ALL aftermarket intakes ? (do they get rid of them?)
I notice with some intakes have ports on top of the cone or inside the airbox for the MAP sensor, but there are some kits that dont seem to have it (or at least i cant see them). Is this true that some kits dont have?
like ZAC, Modal, Arma and some others? thanks in advance

Those are not MAP sensor. It is just simple intake air quality check sensor.
No one used to plug their piggybacks into the airboxes last time I checked. It’s an intake air filter quality sensor.
Oh really because we are logging it in vidiamo to see why my car gives crankcase codes with modal works intakes. Ever wonder why your car got those codes ? Because you removed your air quality sensor.
Maybe that's why kirklandhans tunes kill everyone out there lol. It's a map sensor to see the blow off air that gets recirculated back into the intake..
When you let off wot and your tbs close and you let all that boost back into the intake the car wants to see that air and compensate for it.
Here is what Google gives with that quality sensor part number.

It is 100% not a MAP sensor.
If you are getting a code then you are disconnecting the wire from the air filter sensor,
The part is made by bosch and is a map sensor. Bosch the maker of the part calls it a map sensor!
Call ZAC, Modal or black box and tell them they don't know what they are talking about or call almost anyone in the GLC 63 Club and tell them since their MAP Sensor isn't connected, their 10's 1/4 mile cars are not working correctly....
Tie up air sensors or mount them to the Heat shields if supplied.(these are redundant as they only measure how dirty the stock filters are)

It's still a map sensor! Oh and I worked with modal and he sent me a prototype to connect the map sensors to the intakes.
Have you scaned you car with xentry to see if it has any codes? most tuners will code out the crankcase codes anyway.
How many blown engines so far in your glc clubs? We have one here in our forum also and wonder if he had those just laying behind the turbos
Skratch, do you even understand the logic behind your argument? If those are MAP sensors, the car would flip a **** if you disconnected both of them for intakes.
And I helped ModalWorks test with his prototype 3D printed intakes as well - and I zip tied my AIR FILTER QUALITY sensors out of the way.
Should I post the MB Service service statement I have that calls it “Air Quality Sensor” or will you just post more Google searches on the PN with mislabeled parts?

You want me to post vidiamo data showing the baro readings of that sensor?
So did your car pend those crank case codes as well? I can go months with no codes in xentry and withing 20 min of not having those sensors in the intake my car pends those codes.
99% of the people have no idea there cars are pending those codes and are in limp mode and they think it's because the battery is low lmfao.

if its a air quality sensor, (bad quality air because filters are dirty type of measuring device), then the air pressure in the manifold (chamber) would be low correct?(clogged filters) im not a certified STAR technician but wouldn't it be both those things? how would the ECU know that the air filters are dirty and triggering a CEL if not for the sensor reading that the manifold pressure is low: hence the air quality is "bad" as the filter is gunked up with crap?
seems like there are those with it and those without.

You’ll only throw a code if you disconnect either air quality sensors while the car is awake. Pretty simple to just twist and pop them out of each airbox so that doesn’t happen. I guess I fall in that 1% of people that haven’t thrown their car in limp mode installing an intake on and off the car dozens of times.
I am in that club too. Why would you even disconnect the wires?
I am with ya' ll as well, although I must say ,when I first got my 1st set of Modal intakes, the instructions were "really" clear on what to do with that sensor and or "what to disconnect" - disconnect was the word it used, so I started going for the clip to disconnect the connector, NOT knowing at that time, that you can just twist the sensor and remove from the housing. ( <- and this is what they want you to do, not disconnect the actual sensor)
So I know there are MANY MANY people out there, that have disconnected , damaged, etc etc the sensors, instead of a simple " relocation" of it.
FYI, I never have gotten a code from "relocating" mine, and did the install while my car was asleep. (as I always do with anything on it, unless its required to access OBD)
My car is definitely not in limp mode from relocating air quality sensor from air box for Modalworks intake.
I never disconnected that sensor, but just twist to remove and relocate.

Skratch - of course you are going to see data from a LIVE sensor if you’re logging it. That doesn’t mean it’s a MAP sensor.
Seems so odd that everyone running an aftermarket intake has no issues with what you assume are two manifold absolute pressure sensors being unplugged and not measuring absolute pressure from the car. If they were actually functioning MAP sensors measuring absolute pressure, wouldn’t you think the ECU would freak out out because it can’t read the sensor outputs and therefore not be able to inject the correct fuel ratio?
Sorry bro, but an actual MAP sensor in the context of a turbocharged engine is used in place of a MAF sensor. To try to correlate an air filter quality sensor (to indicate when the filter is dirty), is not even remotely the same as what the 4 MAP sensors do on our car - measure manifold pressure and feed that data to the ECU to adjust air/fuel and timing. Those sensors in the air box aren’t doing jack **** for MAP data, but they are sensors and of course you will get output data from it.
Reviving an old thread here while I was searching for the potential cause of P1CE700 and P1CE800 crankcase ventilation codes. I have a Zac Motorsports Intake and the OEM air box "sensors" (whatever we are calling them) were just in the open air of the engine compartment, mounted in the back of the Zac heat shields next to the air filters. I emailed Greg at Zac Motorsport and he suggested that I try moving the "sensors" into the air filters by drilling an appropriate sized hole in the end of the filter and pressing them in (I used a ~.44" drill bit) . I've completed this mod but haven't been able to test the car since it's been snowing where I live.... But I thought it was important to note for others that may search for answers that Zac Motorsport recommend relocating those "sensors" into the air filters.
