Code 2H

I am getting an intermittent 2H code when hitting bumps. I thought it was a loose connection somewhere but everything i looked at is tight and has good readings. 2 months ago I was getting this code upon turning left or right. I replaced the wiring harness and speed sensor and everything was fine for about 2 months. Now i am getting this code again. It does not code out all the time it is infrequent. I have tested everything on the I-19, I am getting rpm readings on the display, and all connections tested good as described in the book.

I am at a loss here. Any ideas?

Fact of the week
Bluetooth is named after the 10th-century Viking king, Harald Bluetooth, who united warring tribes in Denmark and Norway. In 1997, Jim Kardach from Intel gave the name to the technology because of its ability to unite different communication protocols, just as Harald united various tribes.
