HI again. So, in the continuing drama of O2 sensor replacement in my 05 Pac, I have come across the possibility that 2005 Pacificas built on or before Jul 8, 2004 (mine has a man date of 5/04) may require a 2004 O2 sensor because a change was made in the sensor used.

Can anyone verify this might be the case or have access to a TSB that discusses this? Thanks in advance.

 

no such tsb if in question get an oem one from dealer using vin off your car.
