Differences between automotive & airplane engines

... 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. -- Geoff The Sea Hawk at Wow Way d0t Com remove spaces and make the obvious substitutions to reply by mail Spell checking is left as an excercise for the reader. |
