Fuel mileage loss, fix = clean the Map Sensor again.

Fuel mileage loss, fix = clean the Map Sensor again.
I might just buy a couple of them and replace it every 12 months while cleaning every six months.
I have never had to do such a thing to any other vehicle I have owned. I have never owned a boosted car before.
Cheers.

Why are the o rings different colors? Did you replace them at some point? And what is the best cleaner to use on these?

Same o rings. I guess the green coating came off of it.

I do not know of a recommended cleaner for the sensor. I know carburetor cleaner leaves a lubricant behind when it evaporates which isn't ideal. Brake cleaner works really well but can damage electronic components by removing insulation. Brake cleaners also attack certain plastics and rubber compounds.

I scraped off the big chunks and and wiped the rest off with a paper towel

I wonder if MAF cleaner would work?
I actually just pulled that sensor and cleaned it. When it came out it looked identical to the pictures you posted bradherr. All 4 of those slots were almost plugged solid with soot. My car has just over 35,000 miles. I would definitely recommend that everyone pull and clean that thing at least every 30k. Unless you're deleted lol. The advantages of deleting these cars just keep piling up.

It did seem to help. I used a pick tool to grab all the big stuff and then sprayed it with that MAF cleaner and it seemed to get to all the stuff I couldn't get to. It cleaned it up pretty good. Probably isn't the strongest stuff but it won't damage the plastic or sensor either.

As far as the OP, I wouldn't just replace it every 12 months for no reason. That's a lot of wasted money. Could also cause more issues if you get one that doesn't work correctly. Cleaning it every 6 months isn't a bad idea but I definitely wouldn't be replacing it once a year if it's still working.

I cleaned mine around 64,000 miles for the first time. Looked pretty much like the dirty pictures above.

My method was to use the blow gun on my air compressor (with the pressure turned down in the 40-60psi range) to blow out the majority of the soot. (I use this as the first step on all of the exhaust sensors as well. Since the soot is dry, much of it just blows away like dust, which prevents any risk of the soot caking up with the cleaner and lodging itself into a small hole in the sensor, such as those on the O2/NOX sensors). After I've blown off the soot with the air gun, I have used MAF cleaner and QD Electric Cleaner on the MAP sensor, both of which seemed to be quite effective. (Exhaust sensors usually get brake cleaner.)

Take it out at 200k, that is a nice round figure to start from. :)

Might be a pain but if they cant fix it, maybe try another browser for this forum? Just an idea. I use a laptop and an Ipad, and I haven't had any issues, if I use my IPhone it can get a little weird sometimes.
The mobile forum software wasn't too bad until they updated it a few weeks ago, now it's garbage. The way pages are not really pages anymore is terrible and the page selection thing barely works
I will report this all to AG. Hopefully they can do something about it.

Isurehope...

I sure hope so... but there is another thread on the problem already that is a month or so old and it still hasn't been fixed, so I won't hold my breath!

Thanks for the effort though!

Old problem, fairly easy fix. Either make sure you're not on the very last character of the text box, or hit A/A button.

See thread: http://www.cruzetalk.com/forum/5-cruzetalk-site-issues/180698-cant-space.html

Still, it would be nice to get it stamped out for good.
