I had engine replaced and now have codes 0158 and 0161, both are Bank2/sensor2. Which one is that?
Could blowing old engine have fried this sensor? Should I replace whichever one it is or does anybody think it could be something else.
Ant thoughts on lower ball joints as While under I noticed my ball joint boot is torn.
thanks

bank 2 sensor 2 is the right side ( under passengers area) just replace it, check the wires also to make sure they are hooked up and not pinched since you have had the motor replaced
ball joints best are Moog

Is that the upstream or downstream? Are the wires that come out and go to wire connector part of new one? Do they just unscrew? Any idea of cost?
Aftermarket or Chrysler?
How bout cost of Moog ball joint?

downstream
you can buy ones that have the factory type connector get one of them, got mine at an Auto Value store here SG1389 for 32 bucks I think
aftermarket of course although some will say only OEM will work
Check JeepinByAl he has the Moogs or a local parts store. I replaced mine 3 years ago and they were like 45 bucks I think
