Did a bit more digging and found out that, without exception, I've been
given the down stream oxygen sensor in place of the up stream part I needed
in the first place. (No direct knowledge but seems the parts list/cross
reference data base may be bollixed.)
Second (still working on this) there is some confusion on the correct up
stream P/N for my specific 04 Van. Right now the question comes which will
work on my particular van. the Bosch 15512 or the Bosch 13709.
Chrysler/Dodge has been of little help. Seems the micro give a Schmitt
department is ==> that way. Likely would be better if I could get past the
bottom level of their support group.
OTOH Bosch Technical support has been helpful as has OReilly Auto parts
online customer service group. Kudos to both!
When I get this sorted and the fix done I'll post the result.
An aside. I spoke with the Texas inspection department in Austin and should
the correct part be no longer available I can get a pass on that part of the
inspection. Bit of a chore what with all the forms and hoops I must jump
but I will be able to get the inspection legally.
Connections are correct. The problem comes in the heater resistors in the
upstream are 2.1 to 2.7 ohm in the early 04 (3.8L) van and ~ 6 ohm is the
late 04 van.
That and the vendors were handing me the down stream sensor instead of the
upstream apparently due to problems in the data base.
