[Gmecm] Re: Fuel Economy

[Aaron McBride]

An O2 sensor that reads0-5 volts is a Titainia type O2 sensor, It sends the
PCM a signal based on resistance instead of 0-1 volt like a Zirconium O2
Sensor. 5 volt reference, 3.5-4.5 = rich, .5-1.5 = lean. Not compatible with
the older style O2 sensors, Alot of late model Diamler/Chrysler vehicles
have gone to this style. Aaron
