As defined, both upstream 02's are throwing codes.

Both are new.

It has to be electrical, so anyone know how I should diagnose? Electrically, I'm an ACE....I just need to know the values and check-points for proper diagnosis!

Thanks

Which codes are they? There are only 5 or 6 for each O2 sensor and another dozen or so that are falsely blamed on O2 sensors.

 

Hey, can you do us a favor and tell us what vehicle it is you're talking about in your posts? Obviously its not your 1997 F150 since that isn't covered by this section... help us to help you.

 

Sorry Silver.....and Ken

By now, I just stupidy assumed all knew the dillio with this bucket-o-chit I am building!!!

Anyway....1997 4.6 4x4 turned......97 4.6 Vortech SC turned....
2003 3-door 5.4 SC 4x4
SVT Cluster

C&L Intake
Art Carr 4R100 (as of today, badaz)
SCT Flash Programmer
T-rex
38" tires....bunch-o-redneck ****tolla : )

So....like a dummy, I posted this before trying the plug at the 02's....

I had no V+....that pin on C132 is reserved for COP 2 due to the conversion...

Anyway....great news!!!!! Truck is DUNNNNNNNNN!!!!!!!!

I ran a new wire to the power junction (triggered by relay) and powered the VPWR (circuit 391) via this custom "hack" (lol) and now I'm good. Still have a low fuel DTC, but I am at the point there that a trip to the stealership can remedy my final woe....

All other issues are dead! If anyone wants to do this swap.....I highly recommend TIME and MONEY!!!! Oh....and a DVM!!!!!!

Seriously....any questions....I'm glad to help....I JUST finished doin it. Two years and 10k.....

While I am at it......Stewart.......Mike is awesome!!!!! For those that want to go faster....safer....sooner......C A L L Mike Dunn!!!!!
