Message	I think it's closed when you're under WOT, and that's really the only time that you'd see detonation. Isn't the EGR mainly used under light load such as when you're cruising on the highway?

(n/m) - Kenny 14:29:40 06/30/04 maybe they meant "Inoperative" as in stuck open? (n/m) - ZEngineer (TT) 14:51:04 06/30/04 Open = operating. So, I don't think so. (n/m) - Kenny 15:00:21 06/30/04 can open & close = operative - ZEngineer (TT) 15:04:05 06/30/04 If it's closed, it's not recirculating - hence not operating - Kenny 15:06:41 06/30/04 but if it's not operational, it means it's stuck - ZEngineer (TT) 15:11:17 06/30/04 False. - Kenny 16:02:36 06/30/04 2nd.
