that's our opinion too. we just weren't sure if the sensor could still be bad if the light was off. the dealers don't try to save us money, do they? i should start a car dealership - they're always turning my fritos into their fritos.

thanks ron, we think it was an errant light from a two year old A/C repair. we'll drop you a line if we decide to replace the sensor. thanks, -joey

we'll try it, thanks.

engine light came on intermittently, had it diagnosed by the dealer, pulled code, didn't ask about the code, i'm assuming it indicated knock sensor 1 and 2. engine light has been OFF since the visit several days ago. if it still needs replaced, my grease monkey mechanic could probably do it for 350 - according the sage and welcome advice on price and ease of repair. -joey

thanks. dealer says it's difficult to repair as it's deep inside the engine. sounds like you would definitely replace them? the car doesn't knock that we can tell - but there may be other benefits. what's really odd is that we don't see any dash lights indicating failure. -joey

okay - question number 2. like the previous post mentioned, my wife's LS400 (1992) supposedly has knock sensors #1 and #2 that are bad and need replaced. the dealer quoted $750 total for both. there are no engine or other lights on and i'm not sure if i should proceed. any thoughts? thanks again, -joey

allo all! i'm very happy to see a place i can post my questions. my wife's 1992 LS400 has had the air bag light on for two years. we just took it to the dealership and they say the center air bag sensor is kaput. they recommend replacing for $850 and say the air bags will not deploy until fixed. i'd like thoughts on whether or not to replace. the air bag light has been OFF since the visit. was the bad sensor reading an anomoly? is it okay now? thanks! -joey
