Is this a fancy name for the O2 sensors? I just bought the Haynes Manual to change some O2 sensors, and the Haynes makes NO reference/mention of them -- but refers to "lambda sensors".
Appreciate the help.

Same thing. Don't forget to grease your propeller shafts, too.... ;-)

I don't get it? What's Lambda? Its from Revenge of the Nerds and the 11th letter of the greek alphabet? Propeller? Please don't tell me that's the drive shaft?
Thanks brother!

Lambda = change

O2 sensors measure changing levels of O2 in the exhaust...

that explains it -- must just not be referenced in corny American dictionaries (eg. dictionary.com).

Thanks Lambda Lambda.

I thought Delta = Change?

Delta = difference

Yeah, delta = change, like calculating the slope of a line in calculus, delta y/delta x. Lambda has to do with the reaction to the metals they use in the oxygen sensors to measure the amount of oxygen in the exhaust gas. They use a ceramic-coated platinum electrode and the "burning" of the exhaust gas heats the ceramic coating and then the platinum gives off ions in proportion to the heat generated, this is measured by an electrode, and this is considered a lambda reaction.

...or something like that
