Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I tried disconnecting the battery again and then restarting but it didn't help.
Hello,
I need some advice on if anyone has had a problem with their car entering "limp home" mode. I had my boxster sitting for about a month and the battery died. I charged it up, and got it started. When I went to drive it, it would not go above 1500 rpm. I tried disconnecting the battery again and then restarting but it didn't help. Can anyone give me some advice before I take it into the Porsche dealer? Any ideas of what I can expect?
Thanks,
Jim
Yes. It came up with "P1502 Fuel Pump Relay Output Stage - Short Circuit to B+". I don't know where the fuel pump relay is located to check it out. Can you point me in the right direction?

I also have a 00 986S and have had that scenario happen to me a few times. Not sure if I got that code or not. Whatever it was, it just went away after resetting it. It usually happens after I mess with something such as installing an electrical part like an 02 sensor.
I replaced the relay and reset the code. It runs fine until I turn off the key. When I restart the same code returns and the car goes back into the "limp mode". Anyone have any ideas, cautions, experiences with this?
Like I said, that has happened to me and I have the same year model as you. Try resetting the codes, and then turning the key on but not the ignition. Keep it there for about 30 seconds and you'll notice some of the lights in the dash disappear. That is to let you know that the car is done calibrating itself. This needs to be done after certain types of changes but I do it everytime I install any type of new equipment. Keep starting up the car this way (waiting for aboug 30 sec and then starting it up without turning it back off otherwise you'll have to wait again) for the next 3 or so times and it may fix the problem.
It ended up being the throttle body. I had it replaced. Works like a champ now. My mechanic said that letting the car sit for an extended time might have contributed. To avoid another $1000 bill, I make sure it gets driven regularly now. Expensive lesson!
