Last night I installed a power wire in my Altima.. Here is the chain of events..

I removed the cover to the left of the dashboard, I removed the fusebox cover so I could take the screw out, I pulled the lower panel off, I popped out the ODBII reader, I unhooked the trunk wire, and unscrewed the other screws that were holding the lower panel..

I got my knife and started cutting out the carpet near the grommet.. I then cut the grommet and poked my screwdriver through it..

I pushed the wires through with a hanger and then had to remove the bottom of the airbox to get access to the wire..

That was all last night.. I left the car all torn apart because I was going to run some more wires today.. My wife needed me to go somewhere in a hurry this morning so I had to hurry and try and put it back together..

I didn't put any of the paneling or anything back on.. I just moved the wires that were in the way out of the way.. I went to put the airbox back on I noticed a piece of tubing was off.. I posted a question asking what it was and they said it was coming out of the CVT..

So I put that back on the nipple and clamped the box back on.. When I started the car it lit up:

TCS Off
slip
Service engine soon..

These are the errors I got:

P2138
Type PowerTrain
Status Stored
ECU $7E8
Description Throttle/Pedal Position Sensor/Switch "D" / "E" Voltage Correlation


P2127
Type PowerTrain
Status Stored
ECU $7E8
Description Throttle/Pedal Position Sensor/Switch "E" Circuit Low Input

I tried unplugging the negative for over 30 minutes but got the same thing when I started it up..

One other thing.. I noticed this plug but I don't think it's supposed to be plugged into anything..

Any ideas.. PLEASE!?!?

Thanks

The only thing I can think that could have possibly happened was I knicked a wire in the gromet hole while cutting (don't think I even came close to anything though)..

Or, when I had the guts laying out under the dash I may have shut the door and crimped a wire?

Could either of these possibly cause this error?

Bump for some help on this issue!

Based on your description I think one of two things happened:

1) You damaged a wire by cutting, poking, prodding, etc.
2) You introduced moisture to the system by leaving all of the wiring exposed overnight causing a short somewhere.

TCS is your traction control, and if you didnt drive the car before noticing this problem then you interrupted something in the detection system. When the dash reads "slip" that means it is sensing loss of traction and compensating for it by regulating throttle. You can turn the TCS off by pushing the button which is near the fuse box you were playing with. Are you sure everything went back in the way it came out? Id check all of your connections again...
