Need help with CEL

[markymarc1979]

Hello everybody. Just pulled the 08 E93 out of hibernation and got a CEL on the dash. Scanned the codes and got this result. Did a little searching around but could find much. Anyone else have this problem? The car is supercharged.

Problem with the MAP sensor or wiring. Clear it and see if it comes back. If it does, check the wiring and then replace the sensor. Manifold will have to come off.

Thanks. I did try clearing it and the code came back fairly quickly. I will need to take it in.

Theres not that many reports of the map sensor failing from what I can remember seeing

I had a code pop up for the MAP sensor a while ago. For me, I cleared it and it never came back.

Seems like its an easy job except for the location of the sensor is hidden (in back). See attached..

Being supercharged, you might want to concider new spark plugs while you have it opened.

Coincidentally, I'm getting a Fill Pressure Plausibility, Cold Start Bank 2 code. I get a yellow engine/SES symbol on the display, but I'm not in limp mode. I pulled the plenum this weekend to see if I could gain access to the MAP sensor. As pictured above, it is behind cylinder #8 on the driver side. I couldn't find a DIY, but thought I could figure it out while I was in there. Unfortunately I gave up (Sunday afternoon) and put the car back together for work on Monday. As luck would have it, I found the steps in an online TIS today, but the pictures were very limited. Basically you will need to remove the plenum, remove the secondary air pump and hose, and remove the wire harness on top of the engine. There's a great DIY that illustrates the plenum removal and all the connections that need to be removed to raise the wire harness (see below). From reading the TIS, there appears to be only two bolts holding down the secondary pump, but I can't really confirm this yet. What I can tell you is that there is not a lot of room back there, and it is quite a reach. I think it may be helpful to remove the cabin filter tray, but that is just a guess. If you find a DIY with pictures, please let me know, and I'll do the same. Good luck.
