Reverse Lockout Malfunction after new Master
Okay, so I finally put my new Tick Master in my car a couple days ago. Then, when I went to go drive it, my car wouldn't go into reverse. And by that I mean the reverse lockout gate wouldnt open to let me past the 5-6 shift fork. Plus my PCM threw two new codes at me:
P0102 - MAF or VAF A circuit low input
P0803 - 1-4 upshift solenoid circuit malfunction
I had done the CAGS delete with a resistor when I first bought the car, but never had seen this code before. I also tried disconnecting then reconnecting the battery to get rid of the MAF code, but it's still there.
Thinking I'd just suck up the codes, I unbolted my Reverse Lockout and went for a drive. Well, turns out that ATF leaks from when the Reverse Lockout goes. So, now I have to put it back on and figure this out the hard way.
Now, I checked the wiring harness that goes to the drivers side of the tranny to see if my headers burnt it. It was fine. No melted plastic anywhere. Plus my speedometer works still, which makes me think that it's a bad ground somewhere.
When I installed the new master, I had to fiddle with the large wiring harness that's at the base of the Strut tower. I pulled on it pretty hard to fit the Tick Master in there, so I might have broken a wire somewhere.
Anyone have any ideas? Thanks in advance, and I hope this is the right forum to post this in.

No, I've had the resistor pluged into the CAGS for a year and half now. It's still pluged in, too. I even did my tranny/clutch swap 2 weeks ago, and didnt have any problems with the MAF, CAGS, or Reverse Lock out. They only started after installing the new Master.

The code description you got for P0803 is for an A4. With an M6, that's the code for the skip shift solenoid. Since this stuff is probably all on the same fuse, checking that would be a logical place to start.

^ Thank you Injuneer.
The fuse was blown. Since it was probably because of the burnt 02 extension, I took it out and spliced some new wire into it. Put it back in, replace the fuse, and no more SES. Car goes in revese perfectly now. Thanks alot.
