Code P1139 questions

[Jung]

I had a CEL and got it scanned at autozone (no vag com) and it came up with code p1139. Long term fuel trim, bank 2. I had this same problem, only with my bank 1 02 sensor back in july or june. i changed it out, boosted fine. Now it says the cause of this code is a "failed MAF sensor".. I figured when i saw the code for the bank 2 that it was another 02 sensor. so i ordered up a 02 from autozone right away. i read the receipt for the code later and it says "failed MAF sensor". Now I was doing the install of the 02, had the y pipe off, unplugged the sensor, unscrewed the coolant exp tank, i placed the 02 socket right on the sensor with my hand. Then i took my breaker bar, thinking i'd be able to torque it off and tried to get it into the 02 socket, but i slipped a little bit and hte socket fell down into the black hole we call an engine bay. I thoguht "great, i'll just use my magnet". I still can't find hte socket after using lights and this long magnet to try to grab it (it is magnetic), but i can't find it. Where the HELL did this thing go!?!?! I mean it can't go far. I heard it clank in there. it didn't hit the ground.
if anyone can just gimme some advice that would be amazing

This may be a dumb question but it wasn't in your post. Have you taken off the plastic belly pan and taken a look at this from underneath? It should be a lot easier to see from there. try removing the front tire and taking a look that way too. good luck.

that belly pan got ripped off about a week and a half ago cracking my front bumper like a mofo with it. It didnt drop onto there. i jacked the car up a little bit trying to see if it would roll out of its hiding spot, but to no avail

It's probably on the subframe.

I remember i droped the coolant temp sensor litle clip. It has fell near right turbo. Could'nt find it from above.
I had to lift the car, put her on jack stands and found the clip on subframe.
Good luck.
You can't leave it there, as i might fall onto the pavement and hit someone else windshield.

true true.. well to my surprise i had a lot of money on my autozone card, so i bought another sensor socket and finally managed to break it free, got the new one in, and it's running normally again. I'm going to take it to my local garage tomorrow so they can throw it on the lift and find the other socket.
