Threw the "Reduce Engine Power" msg and CEL

[s2kstephen]

Well, I went mudding and washed my engine bay and underside today. After I left the wash bay, I got the "Reduce Engine Power" message and a CEL. Pulled over, unplugged the battery, waited 10min, and restarted it. Ran fine with no CEL or message. As I began driving, it popped up again. I pulled over, turned it off, etc....It finally would start showing that message and wouldn't allow the car to rev or gas to be applied.

Did I #$%^ something up bad? Or maybe something got wet that shouldn't have. I was trying to be careful to not spray anything electrical in the engine bay...

Any thoughts or ideas?

Here's why I washed the engine bay:


Here's the truck being dropped off at the shop:

Was the truck running when you washed the engine bay and if so did you notice it running weird at all at any point of the washing? Could be a simple fix with all the electrical items in the engine bay, hopefully it's just water in a connection!

Yes, it was running while I was "carefully" washing the engine bay. I'm hoping whatever it is I got wet, will just dry out and I'll be up and running in no time

Turns out I had 3 codes: all having to do with the intake, throttle body, and throttle body sensor.

1k later, it's fixed!

What did you replace I just replaced my gas pedal and it fixed the problem

I'm curious to know what got replaced too. I had a reduced engine code come up and it said app sensor. Hasn't come back yet so I haven't done anything

I had the throttle body, throttle body wiring harness, and intake filter replaced. Cleared up all 3 codes and it runs like a champ now.

I'm guess I sucked up a little water which got to the TB, and while inspecting that, the TB wiring harness was corroded and all kinda of hacked up (guess from a power commander type device by the previous owner).

None the less, truck runs great now!

Glad you got it up and running! Looks like you had some fun in the mud! Got any more pics?

No pics of the actual "mudding". Those were taking when I broke down while waiting for AAA.
