does anyone know if this is a fuse ?does pulling the ravelco hub trigger this ? I'll clear the code and then it shows up again day's later.someone mentioned a fix for this awhile back and i shined it on ,now i'm sick of it .My banks six gun diagnostic app is where it shows up not the check engine light? I mentioned the ravelco anti-theft pin- hub cause that throws the fuel pump circuit every time but not the "B" circuit brake switch,I don't pull the ravelco all the time and I never remember that being a trigger.

 

The pressure switch on the bottom of the master cylinder is faulty. There are 2 there, it's the one at the front. This switch goes wonky and disables the cruise control, easy fix.

 

I have an intermittent cruise control. Some days it works, other days it doesn't. Sometimes after restarting it flips the other way (works or doesn't work). Would this behaviour be related to that switch you mentioned? My Ford mechanics don't seem to want to diagnose. They just return the truck and say it worked for them today.

Yes this is what my truck was doing. Pressure switch on master cylinder(front one of two) fixed problem.

 

I had the same code and symptoms. Replacing the switch on the master cylinder fixed it for me

 

thx, I will post an update after trying this.

 

Thanks for your reply! Gotta try that

 

Update: I replaced the switch and the cruise control works now!

 

damb i feel so cheated my master cyl. only has one switch
