Exactly what do the 2 oxygen sensors do besides turn on the SES light?

Do they both or just the one ahead of the cat?

BTW -- neither the O2 sensors, nor any other sensor, turns on the SES light. The PCM turns on the SES light -- based on the data that it's receiving from the various sensors. I'm sure you can find loads of information on this if you Google for it. >NapalmHeart wrote: >> "tromboneguy" > wrote in message >> ups.com... >> > Exactly what do the 2 oxygen sensors do besides turn on the SES light? >> > >> Provide data to the PCM. > -- Regards, Doug Miller (alphageek at milmac dot com) It's time to throw all their damned tea in the harbor again. |

My understanding is that the downstream O2 sensor (after primary CAT) gives
a check against the Upstream (at exhaust port) sensor. The downstream sensors are supposed to last much longer than the upstream one. The downsteam one also measures the effectivenss of the CAT.

IMHO: Make money for the O2 sensor companies, who paid lobbyests to brige politicians into requiring more restrictive emmission controls. They seem to balance and measure the efficency of an engine, and catalytic converter to keep bad emmisions low. If the engine has O2 present at the exhaust, it had enough for the ignition. So I've been told. tom @ www.MeetANewFriend.com |
