OBDII came out somewhere around 1996.

I have never heard of anyone personally having their vehicle go into home limp mode.

Anyone reading ever have their vehicle (not themselves) go into home limp mode?

Limp mode is better than tennis shoe mode.

it was designed to allow the car to still run to get you to a repair facility and have the issue checked out. i know with ford, the EEC V system generally takes its time getting into limp home mode by trying to head off some issues by actively changing the tune to avoid many issues. the older EEC lV would jump into limp home mode when a problem bad enough popped up.

as for having it, i think pretty much every car has it these days with the advent of OBD ll.
Up to 60? Thats not limp mode.

My volvo went into limp and 15 was top speed.
Turns out I blew the turbo.

BTW, if you stop and turn off the ignition limp will often reset so you can get home in less than the 3 hrs it took me.

Not sure if all OBD-II cars have it but every modern car I've owned has.
They started using the OBD plug in jan 01, 1996 !!

Why does that sentence require an exclamation point, much less two?

Has anyone here owned a vehicle that has gone into limp mode? And what was the problem? And what was the fix?
