Hello everyone, so I changed both of my air/ fuel ratio sensors, i had codes p2242, p0430 and p0420. (LS460 2007)

ok, since the original harness wires were so short i decided to use the old sensors wires as extension to make it easier in the future if needed. so i did.

bank 1 all good.

but on bank 2 the original harness socket was damaged and couldn't fix it so i cut it and connected it to the extension wire using tube wire connectors.

for 3 days im testing the car to see if the codes are coming back, and today i got the p2241 for bank 2.

so im thinking what's wrong? why only bank 2? because of the tube connectors not being in the range of sensor's current and voltage, it has too much resistance or its too weak? or the sensor is down already? or what?

what do you guys think?
