Hey everyone. My name is John and I am new to the site and fairly new to the world of Jeeps (ex gf had a 2000 Sport and I fell in love with it). I just bought a 2001 Sahara, 4.0, manual, and I went to get the smog done, but the O2 heaters will not go into a ready state. I replaced all 4 sensors with Denso sensors. I am still having the problem. The sensors themselves are ready. There are no CEL codes. Any suggestions?
2001 Sahara O2 sensor heater issue

Dealing with the same thing right now on my 2000. I haven’t replaced any sensors yet. I’m hoping that driving it will clear up the issues.
Long story short, I finally got it to go. It took about 500 miles of driving to figure it out. The day before I got it to work, I drove approximately 10 minutes from a cold start and did not hit my brakes during the drive. I kept the speed between 50 and 60 mph. I drove it back, let it sit overnight, did another cold start, let it idle for 20 minutes, then turned it off for 10 minutes. When I checked the heaters, they were finally completed. If you dm me your number, I can call and explain a little better.
Fixed. Came outside this morning and turned the key to “on” and let it sit for 10-15 seconds. Started it. Warmed it for a few minutes. Drove 1.5 miles to the freeway and drove the snot out of it for 15 minutes. Got home and the heaters were ready.
