Lift pump circuit code

[I6FREAK]

So after 10 months of no CEL I got a lift pump circuit code(230). I am not using that circuit and the plug has been hanging there for a while now( 10 months). I also noticed that the grids never cycled after I started. The wts light went on for about 2 secs then shut off. The CEL turned on before I even started it, I just turned the key to the "on" position and it illuminated in about 1 second.... Any ideas.... That was the only code. I can clear it and it will come back in no more than 2 start cycles.thanks,Will

Mine hung for long time with no code. Maybe some dirt got in there and shorted it hard to say. The grids will not cycle above 60* I believe. Once the truck sees the temp it will shut off the lite if not needed. Just went out and tried it on mine and the wts light went out in less than 2 seconds. Try cleaning the harness and see what happens. If everything else is in good running oder, I dont think you have a worry.
