Need help diagnosing MAF issue

[buttershxc]

This is killing me having to post this. But I'm pretty frustrated.

2003 1.8t

I'm getting several codes that happened put of nowhere.


01 Engine Control Module 1

System description: 1.8L R4/5VT G
Software version: 0003
Hardware number: 8E0909518AF
Coding: 0016701

Trouble codes:
P1118 - Bank1, sensor2, heater circuit Open circuit No signal/communication
static
P1289 - Turbocharger recirculation valve Short circuit to ground Lower limit not reached
static
P1114 - Bank 1, sensor 2 Internal resistance too high No signal/communication
static
P1116 - Bank1, sensor1, heater circuit Open circuit No signal/communication
static
P0102 - Mass or Volume Air Flow Circ. Low Input Lower limit not reached
static

In short. I've replaced the maf with three working units and VCDS still shows 0.00 reading on Group 3 Block 4. I checked the voltage on pin 2 and I'm only getting 3.15V to the maf with the key turned on. I replaced the pigtail harness on the maf and searched for a cut in the harness and still no bueno. Car runs good but I can tell my fueling is off. I have also replaced the bank 1 o2 and nothing changed. What the french. Toast. Thanks everyone.

what are you using to read mvb??Also did you replace both 02 sensors?Are you trying to read mvb after you clear faults??If so your reading will always be 0.0.Readings must be read before clearing faults.Also if you have a vag com read ecm mvb 32. The reading is normal +/- 5%. If its -25% or +25% its either a large vacuum leak or a bad maf. Also check mvb 3 or 5 for the maf sensor Gm/s reading.

I use obdeleven but I do have VCDS. Mvb 3 and 5 both show 0.00 Gm/s and mvb 32 just sits at 0%

Fuse #34 was fried. Put in a new fuse and now it won't stay running, sputters and dies. I like a good mystery.
