I replaced only 1 that was down on bottom of motor. The top one when I have enough money soon enough which is ok and not damaged. The bottom one leaked exhaust fumes before replacement and now it's okay besides codes for downstream bank 1? I think it was p0104. It runs okay. But I still need one at catalytic converter changed still. Will this clear once I do, even though they were not changed out at the same time?Please advise.

Hi,

The code isn't correct. Let me know the correct one so I can check into specifics for you.

As far as your question, yes, the parts can be changed at different times. If the problem is resolved and the code is cleared, the light should stay off. The only issue is we aren't sure if it is a sensor or something other causing the code you are seeing.

Let me know what the code is.

Take care,

Joe
