O2 sensor help

So I got 2 codes showing that my bank 1 sensor 2 O2 sensor is was bad. I replaced the sensor and still get the same codes. I though that I may have gotten a bad sensor, so I got a replacement. Same thing. Is there a common issue I'm missing? A wiring problem I should look at? Any help would be great, as my inspection has expired and I can't get it inspected until the CEL light is off.

Before changing any sensors, check your number 16 fuse in your Power Distribution Center. That's the fuse box under your hood next to your battery. In some years, it's a 10 Amp fuse, a 15 amp in others.

It's probably blown and thus, setting the code.

a code does NOT indicate a component is BAD.

P0132-1/1 O2 SENSOR SHORTED TO VOLTAGE

POSSIBLE CAUSES
O2 SENSOR OPERATION
O2 SENSOR SIGNAL SHORTED TO VOLTAGE
O2 SENSOR SIGNAL CIRCUIT SHORTED TO O2 HEATER FEED CIRCUIT
O2 SENSOR SIGNAL OPEN
O2 SENSOR GROUND CIRCUIT OPEN
O2S HEATER FEED CIRCUIT OPEN


use only jeep or NTK sensors.

When I see the price of OEM I think aftermarket.

Mattyjm, You, my friend are a God amongst men. The fuse is in fact blown. Now I just need to go out and buy one.

Thanks for the compliment, but I'm the furthest thing from a God you'll ever meet. I'm just a multi-WJ owner with a little experience. Glad I could help.

When my #16 fuse started blowing in my 2000 WJ 4.0L i6, I replaced the 10 amp with a 10 amp and it blew it again the next day. I had no more 10 Amp fuses then, so I stuck a 20 amp in it's place and it's been well over a year since that happened, and it's still in there.

I can't recommend this substitution, because it's the "wrong" thing to do. I can only tell you what worked for me.

Saved me a bunch of money as well as I had a similar problem. Didn't know there was a fuse for them so I checked it after reading this. Wasn't blown, but wasn't pushed in all the way either. Blew it out with a little compressed air from a can and put the fuse back and the CEL is gone, it stopped idling like crap, and my fuel mileage is back up around where it should be.
