2005 Chrysler Pacifica Limited 3.5L MIL Lamp on
Posted to Chrysler Driveability on 12/22/2009 7 Replies

I am checking the catalyst and O2 operation on this Pacifica. The O2 sensor readings on the scanner are 2.5 to 3.5 volts, fluctuates back and forth, desired is 2.7V. Why are they not the usual .2 - .9 Volts and fluctuating? Does Chrysler do something different...
