Go to the "FAQ" section at the top of the 24V forum. In the FAQ is a thread titled "24V codes" where you will find out what your codes mean. Could be the VP is bad or the ECM.

Godspeed,

TDeltonto , code 0234 is a over boost code, 0232 is fuel shut off signal votage to high. Try clearing the codes, and see if they come back. You need to fill out your signature, so we can see whats done to your truck. Makes problems easier to figure out.
