First off, I'm sorry I haven't dug as deep as I probably need to. I'm trying to get parts ordered before the shipping cut off so they're shipped today and figured I'd ask for a quick answer vs. spending an hour looking for it.
I'm trying to diagnose limp mode on my 04 Jetta Wagon. I unplugged the MAF sensor and ran it.
From what I gather, if it performs similarly or is significantly improved, it's a bad MAF sensor. If it performs worse than when it's plugged in, it's not the MAF sensor.
My question is this - it performs exactly the same as when my car GOES INTO limp mode. However, it's quite a bit worse than how the car performs before it goes into limp mode, right after starting it. When I unplug the MAF sensor, it's acting like it's already in limp mode - no boost.
Usually I have to get it up to about 70 on the interstate or really get into it in town to get it to go into limp mode. When I unplugged the MAF sensor, it appears to have no boost right off the bat.
Can I assume that the problem is not the MAF sensor based on this?
Thanks!
