Does anyone know where i can find out what the different error codes means???

Got 1693 and 0234 on my vehicle and then the engine stopped while i was driving,
now it won`t start. The engine doesnt ignite when i try to start.

 

these might give you a clue, but I'm unsure if these are the same since this was off a 2001 listing

P0234
Turbo Boost Limit Exceeded

P1693
DTC Detected In ECM Or PCM


sounds like you might have a boost fooling / fueling box thats not working properly
