- 2003 Explorer XLT 4.0 AWD
I just picked up an 03 Explorer XLT V6 that was showing a P2198 code - O2 sensorf stuck rich, Bank 2 sensor 1 - so driver's side upstream sensor. I picked up a new one and swapped it in and the code has gone away. My question is, should I replace the one on the other side as well? Or even the remaining 3? Or just leave them as is until I get another code?
