Codes
I just got my 95 LS400 the other day and the CEL popped on today. One code is P0430, which I know is oxygen sensor related, and also P0510.
I'm not sure on the 510. What's that one for?

PO510 Closed Throttle Position switch
codes are so easy to find, i think your wasting asking..... took 8sec for me to find and copy this.
Loogle is your friend. type in obd codes and the code and it will bring up like 10 sites. Usually it s on you dont even need to navigate to get the meaning a code. just sayin. next time try a search of some kind.

you should also know that p0430 isn't usually an O2 sensor code (when they die they usually bring up multiple codes for the exact sensor as well).
Go check for an exhaust leak near bank 2 iirc. cat to y-pipe gasket is a pretty common failure.

What I'm wondering about are common fixes for the code, and not information on how to search. Do you have constructive, helpful information on what the 510 may be? If not, stay out of the thread, please.
I'll check the exhaust system for leaks.
Any thoughts on the 510 code?
