Yea...all of them.

The OBD-2 standard, which all cars sold in the US have had to meet since
1996, demands that if the O2 sensor goes bad, the "limp home" or "open
loop" mode (in other words just what you want) must be good enough to not
only run fine, but it's gotta still pass the smog check (750 PPM In my
state).

OBD-II requires you to set a code and turn on a light. It does not require
any kind of performance once the failure has been detected. On the other
hand, I don't know about EVERY brand, but the ones I work on will run just
fine with the O2 sensor disconnected. We try very hard to make sure you can
make it home in the event of just about any sensor failure.


If your computer has a "closed loop" mode, great, but there is no
advantage to insisting on a computer that CAN'T use an O2 sensor if one's
available.

Just put some black electrical tape over the "check engine" light and
you're as good as if you'd spent $2K on an aftermarket ECU!

Yea, the bulb takes a LONG time to burn out on it's own.
