I'll give a try and let you know if it works else ima try a new downstream. Thank you for all the help.

Also did your o2 simulator you have in your thread make your cat ready up ?

Thank you , yea maybe it’s the cat. The car runs great. The thing that scratches my head it passes the sniffer test and also after around 1k miles no check engine. Might try some Cataclean or something and see if it sets.

It is a 99 4x4 CA emissions, my CAT wont ready up and I think this is the issue. The car has no codes or pending code. During smog it passed the sniffer and visual but failed for Readiness. Funny thing is car idles and runs flawless. So I think the 02 sensors got swapped by previous owner...

Hey bumping this thread cause I can’t post my own. But my bank 1 is acting as a downstream and bank 2 is acting as an upstream . Bank one is steady between .5-.8 and bank 2 moves with throttle input. Is my ob2 labeling it weird , I’m using OBDLink

Push voltage to the actuator manually
