And ABS lite on - sounds like wiring damaged
or 'chewed' by rodents ??
Or "dirty" connections , chassis grounds .

Your bad pcm did not show you the bad sensors
now you can see them
What year
the o2 sensors 4 wires
1 ground
2 sensor ground to comp
3 ASD voltage
4 sensor signal
sensor ground to comp is the same for all sensors
to comp, TPS, MAP,IAT o2 all come back to same
ground wire on comp
The ASD volts also powers the injectors I think
you have a bad o2 ngk.com get a new one
ASD is batt volts on off with key
get a wire diagram for your truck check wires
for short or open
if all good replace sensor
Its 99% of the time the sensor not the wires
unless some maniac was mesing with wires pinched
or cut this can also take out a comp if ran
shorted to long but is very rare

thanks for the reply!!
sorry guys!!should post it in the first place.
the truck is: club cab /2003/3.9/85000 mil./4X4
a lot of mods including vortech s/c
today original ecu plugged back in ,all codes gone.
i was testing the other one for reprograming(flash) purposes
is there any possibilites ,that the donor truck had different O2 sensors set-up??(the donor truck same year ,and ecu same part number,they all match)
If yes -how to make it work on my truck
O2 sensors are NGK two months old.
thanks!!!
