I know thats what happened to me. If its the electric plate or TCU ur gonna start experiencing limp mode on and off for a bit with no CEL. When the speed sensor completely fails ur gonna be in perma limp mode with a CEL. Like I said u might want to start investigating it a bit more before it happens because it sucks!

I was turning my car off in the beginning when it went into limp mode and back on corrected the issue for a short time and then the intervals kept getting closer and closer to the point i couldnt even drive a mile down the road before it went to limp mode.

I bought my plate new from a dealership on the East Coast for $278 which isnt bad.
