Updated Accelerator Pedal?

[BigBlue2014]

So I am one of the few that did this a few months back because I had a bad pedal that was throwing a P2138 code. After some research I found others had the same issue and it was one of 2 things. The accelerator pedal or the connector going to it. Others also mentioned that they had their CEL go on when taking hard left turns (just like I had attempted). Thinking back, the last few times it happened I was taking left turns as well. Left into work, off the main road into my parking lot, and also a hard left turn on a winding road going uphill. So this all makes sense.

So it appears that GM has revised it in 2017, and the older version (that I have in my truck now since it is a 2014) is discontinued. Another benefit from replacing the pedal is that people reported that the response time (at least in the trucks that had the older version of the pedal) has improved and the lag was reduced a little bit. So soon I picked GM Part number 23362231

 

A T27 socket and 2 bolts later I had the old one out and was able to put the new one in. No programming was necessary and the drivability of the truck was a night and day difference. The first 1/3 of the pedal used to be a dead zone, and it is not anymore. The response is instant and smooth all the way through out. As a note, I have a wood brace under the pedal frame to stiffen up the assembly as well, and that has been in the truck since the day I bought it. So anybody running a truck that is a 16 and older can benefit from this.
