hello scotty, my name is david and i just bought a 02 nissan sentra se-r spec v with 28,999 miles and i was able to drive it for a few days then one day i was driving to work it was very hot then it threw code p0605 up which is a ROM only error. so basically the code wont come up until it is warmed up then the code goes on and goes into failsafe mode. the ecm looks pristine. im failing hard can you please help me?

Has the PCM been reprogrammed for your specific vehicle? Often times the vin will need to be programmed to it as well as some other things like throttle control and the security system.

so that code means a bad ecm no matter what correct? it goes into failsafe mode so its not relle driveable but i already have a new ecm. should i check anything before i plug it in?

That code ALWAYS means a failing ECM, no way past that. But if it runs ok, ignore it till it runs bad
