i have extras but a paid 85 a piece so if you can get them for 45 you should at least by 2 if not 3
my car was burning them up for a while and at the time my tuner was in the next state over i had to keep them on supply
again if you found them for 45 bucks thats a hell of a deal!

according to my last new map sensor in bag
acd# 213-3843
gm# 12592016
if its those part numbers your safe!
this is stock map sensor for 08 tc
hell yeah mccullj we have a good group of balt owners here in indy you will have a blast!

Just curious...what makes you think its the MAP sensor?

For me, my RPD read data not available and threw a CEL, which scanned as a MAP sensor short

Thanks for all the input guys. Yea thats the part number I have but on gmpartsdirect is doesn't specify that its the MAP. It just says "Sensor" something...but yea. I think its the MAP cause a buddy of mine was watching my car through HP Tuners and he said that the MAP wasn't responding to anything at all...plus the codes I have all came from the MAP.

I ordered mine two weeks ago, and gave you the exact number from my receipt
Score the stocker for now, then upgrade to the GMS1 sensors ASAP and ask Vince or your trifecta dealer to adjust your tune for them. I can almost guarantee that at 25psi* you will be back in this same situation sooner than later.
*Not that boosting 25psi is the problem, but my theory as well as others' is the sustained voltage that 25psi represents is apparently too much for the 2.78bar sensor to handle. With a 3.30bar sensor, 25psi isn't as high a voltage.

If you want to CONFIRM it is your MAP sensor, pull it off.
I'm willing to bet it's covered in oil.
Then buy a catch can from MPx haha
PS: I think the CEL code is po107 (map sensor low input)
Are confusing MAP sensor with MAF sensor (which is on the INTAKE and can get oil on it)?
I think stock reads up to 24 and change. However, you won't *burn it out* if you boost over it's readable range...it just won't *read it*.
Of the dozen or so LNF sensors I've seen or heard of going out, it always takes place during a boost spike. I figure if its not the pressure causing the failure, what other component could cause it to fail? My best guess is a corresponding voltage spike essentially frying it. I'm always up for hearing contrasting opinions though. I think figuring out exactly why would best benefit everyone.

The MAF, in stock location should never get oil on it. There would have to be pressure traveling towards the intake filter.
When you have pressure traveling through the motor, and it is then told to "blow off", it will eventually bring some oil with it. This oil then travels through the valve cover/turbo breather, and is next pushed through all of the piping by the turbo. Oil is commonly found on the intake tubing because it is closest to the source of where the oil is coming from, but if it is in your intake, I am willing to bet there is SOME in your other piping. It will be significantly less quantities that in the intake, since it travels a larger area, and is being thrust through.
Mine died, because it was covered in oil. That is a fact. I can post a picture if you would like. I might anyway, because I have not seen a thread with great info on the subject
Actually he makes a good point. Once of the *blown* MAP sensors that was pulled recently here locally was covered in gunk/oil. (Even more reason to install a catch can.)
Thats just the thing though. It just stops reading it, for good. It doesn't just stop reading in the upper ranges, it stops reading altogether. Thats about as *burnt out* as it gets.

I have never been past 22psi, so I cannot account for over boosting the MAP, but going further on my theory, at 25+ psi, more oil would be thrust through that area, and when the MAP is already pushing itself to the limit, even a micron of oil could push it over the edge.
It would be interesting to try cleaning my sensor, to see how the MAP handles itself. With what I have seen/heard so far, it acts like a fuse, and it can only burp once
I am not confused

I like how you say *blown* because it is not definitively blown, but the oil causes it to "short". The CEL code reads low level input, which could also mean that it is simply not receiving enough data past the oil. I should try and clean my "dead" one out, and see if it will properly read again, but at $45, I did not worry about it.

If we can manage to get together this weekend, a couple of local guys and I are going to test this very thing! We have a sensor that went out recently, and are going to attempt to clean it and reinstall. Chances are it is going to fail again since thats the tendency so far, but who knows maybe it'll hold up.
In what way did that sensor eat ****? Oil or boost?
LOL hilarious, considering one of us is an Aggie . Actually most Houston LNF balts had their MAP sensor go out before it became a common trend on ss.net. We thought it was the heat and humidity at first. lol
Definitely not boost alone, as discussed already. Like I mentioned it was pretty gunked up, but then there is also the theory about it going out due to a voltage spike caused by a boost spike. I'll report back after we do some testing with the dirty sensor.
