OK, I'm just going to walk away from this and you. I think everyone sees the picture here. Have a nice life.

Wow. What just happened here?

I'll take responsibility for causing this confusion and try to clear up my posts, as best I can:

Sensor #1 discussed was the MAP, which plugs into the intake manifold on the driver's-side rear of the engine. This sensor was discussed first, since the code reader the OP originally used pointed to the MAP. Myself and a few others offered input about cleaning, etc, and posted a link to the thread in the tech section dealing with the MAP sensor. Then. . .

Sensor #2 discussed was the Intake Air Pressure (Mercedes logo, right-front of the airbox) sensor based on the advice of MrMopar64 - a poster I think we all can agree is very knowledgeable about the CRD - which reminded me of some other posters experiencing similar symptoms whose fix turned out to be the Intake Air Pressure sensor. I picked up that thought and ran away with it, to the detriment of this posts' cohesiveness.

Sensor #3, the Mass Air Flow sensor (with red tab, on intake tube leading from airbox to turbo) seemed to come up because a poster was offering another alternative, based on experience, to look at if the other two sensors turned out to not be the issue. Somehow a flame war ensued, which I take responsibility for since I derailed the whole MAP-to-Intake-Air-Pressure sensor to begin with.

CHenry, hopefully cleaning the MAP and checking the connection on the Intake Air Pressure sensor has fixed the issue. Another member some time ago ended up having to replace the MAP sensor, and that solved his problems. He listed the part number in the Tech section if you need to go that route.

We're all good. Back to civil disagreements. In these pics, where is the Mercedes sensor?

Thanks, linewarbr for putting this thread back on track. I thought about doing this yesterday after all the foolishness took place but things were too heated. Noble of you to take responsibility but it wasn't your fault; I was following things fine. Now............ back to my question, sensor #2, the intake air pressure sensor, can it be cleaned or does it either just work or not? I checked the wiring and connector seems firmly mated.

See last post on page 1 of this thread. It describes where this sensor is.

So where the little silver colored screw head thingy is? Hmmmmm. That location is filtered air. Shouldn't need to be cleaned. Things went bad quickly, first on page one, (confusion on air box location),then (mud slinging) on page two. Words like "aszz, fuks, and schit" have no place in a sensor discussion. I for one am sorry I pushed the lads buttons after I took offense. I'm only human.

OK guys...just keep the good info coming...understand that confusion can occur on the internet...and leave the garbage talk for sporting events.

I don't know of anyone that has ever had to clean Sensor #2. The only times I know of people having trouble with them, the wiring itself or the connector had gotten loose - it's easy to overstress the wiring when changing air filters.

The only situations I can think where it might need cleaning is if you got into a lot of mud that made it's way above the filter, or if you still have the CCV hooked up to the intake and overfilled the engine with oil, causing more oil than normal to enter the intake pre-turbo - which would then run down into the filter. Another possibility would be if you use an oiled gauze filter like a K&N, and overoiled it.

You bet DW.

Look at this post of mine for the part number, the Mercedes Logo sensor was $62 at a Mopar stealership.
viewtopic.php?p=558596#p558596

The Mercedes Logo sensor is ALSO a MAP sensor, it just happens to be getting used to measure the ambient air pressure. I tried cleaning mine with contact spray - No change. It has a TINY hole in the end of it, and wasn't gunked up at all with oil, so I have to conclude that the sensor just failed out.

My CRD is still behaving badly (not smoking much anymore, but STILL a power loss at low speeds on acceleration, usually when I NEED that power for pulling into traffic) BUT it is recovering a lot faster now. I suspect that the MAF sensor is part of the problem, I have not yet unplugged it or replaced it.

I'm going out for an errand later this morning, I *will* remember to unhook that thing and post my results later today.

The mercedes logo sensor is not a (M)AP sensor, because it is not in the (M)anifold. I think this is causing a lot of the confusion people have.

While technically correct, have you called and talked to Mercedes about that sensor? It IS a MAP sensor, because that is how it is used on Mercedes vehicles, and how they have it listed in their system.

I do not know why VM and Chrysler chose to use it in the way that they have, but it IS an Atmospheric Pressure Sensor, even if Chrysler's system does not refer to it as such.

In the parts fiche, the ONLY place I could find a listing for it was in the "engine sensors" image, which was nothing more detailed than a front-view of the entire engine with sensors spread around the image. The Mercedes Sensor in that image is like #19, in the upper left hand area above the engine.
