When you brought the car for service, were you still having throttle problems? (Re-read you post and see that you still got limp mode.) Did your Boxster throw another CEL for short in the fuel pump? If no to both, I am inclined to think that perhaps you brought the car to be service a little early. A good drying out may cure the short. Just don't drive while it dries out.

It would also leave me uncomfortable if the tech came back with as quick diagnosis as he did. However, I'm no mechanic; I just play one on TV.

PS - I just checked over at Renntech. For fuel pump relay output stage, short to B+, the listed P-code is P1124, fault code 167, fault type 4. For P1502, Throttle jacking unit, spring test.

Any resolution to this problem Perfectlap? Was curious what the outcome/verdict was on this issue..

$570

98Boxster was correct I was looking at the wrong error code (for earlier Boxsters).
An entirely new throttle body was installed. Part was like $350 and the labor was two hours. Car works fine now.

I never got an explanantion as to why the throttle body would go short after the interior was soaked. The way these guys were operating on this day seems like they get an error code read on their computer, the computer tells them what part needs to be replaced (in my instance the tb) and the tech installs it.

I talked to the tech and he showed me the 5 printout of what their computer tells them to fix. Seems like there is VERY LITTLE guess work.

as for the top relay, that was annoying. The new relay that I installed myself had come loose. They pushed it in all the way and the windows stoped lowering when going over the bumps with top down. This close to spending $130 needlessly.

Good to hear you are up and running

I would be curious as to how that rain may have affected the throttle body as well...We had a torrential rain out this way a week or 2 ago, tho my top was up....Was more concerned about the chunks of hail damaging the exterior of the car! No damage to the car, just a cut on my forehead as I got caught out in it while fishing....

the only thing I can think of is water getting onto the rear shelf or dash and somehow....I dunno

lesson to all: A little water in the cockpit can be just enough to cause a big repair.
