P0638 - 2nd Throttle Circuit Malfuntion

[warp9.9]

Hey bud not sure if anyone has been messing about under the tank. But check the secondary stepper motor plug to make sure it's connected. And take a look where the wires go into the motor to make sure there is no damage. After that I would clear the code and run the secondary motor test to see if it stays clear.

Made a cursory inspection and didn't see anything loose but will look closer when I get it up on the lift. For now I just put her on one of my rockets and sent her on her way. I won't have a chance to look at it for a couple of weeks so if something else comes to mind sing out

So now I know where to find that Predator exhaust... If I got past you and any armament you have, I'm a big guy but betting she could take me!

The first thing I'd do is unplug the secondary stepper motor, clean the plug and plug her back in.
