Hey guys. I’m getting an intermittent 21 code, Oxygen sensor. It’s been throwing this code ever since I’ve bought the Jeep 3 years ago. I replaced it with an NTK. Still throwing the code. Any body have any information on this issue, or a wiring diagram, possible fuses? There’s also a 12 code that’s always there. Rarely do I disconnect the battery. It’s a 95 sport 4.0. Thanks.
