Easy fix for my Jeep Wrangler
2015 Jeep Wrangler, code P0157. Replaced bank 2, sensor 2 with this Walker Products O2 sensor and cleared my code. Done. ✅

Looks well made
Looks very good quality and value. I have not fitted it as my problem cleared after fixing a leaky water hose, I suspect it was somehow dumping too muck moisture into the exhaust system … causing the issue

Perfect OEM match!
Perfect cable length and plug type. Perfect readings and fixed my problem. Fuel trims are right where they should be now. Car ran horrible before I installed the new sensor. Now everything runs perfect.

Does not work for 3.6L pentastar!
Do not buy! Listed as an upstream sensor. Thats wrong. I had more check engine codes pop up because of this thing. Replaced it with an AC Delco and all codes cleared. DO NOT BUY THIS SENSOR

Nice sensor - Comes with thread treatment already applied for ready to go installation.
Perfect fit for the firewall side Cat O2 sensor. Existing sensors are 0.8v and this one is 0.72v Not sure it that matters, or if they generally fail upwards as they age. Computer is happy and check engine light is off. Make sure you get the 22mm O2 wrench which is a necessity and a snipe to extend your breaker bar to about 2.5 feet. Removal was while the car was lifted on the front passenger side to the maximum of the jack and then supported. That gives you the best angle to crawl under there head first if you are right-handed. The upper sensor would be a bit trickier and perhaps better to do from the top. Either way, if you have to do one of the firewall sensors you are doing all the hard work and should probably do all 4 on a higher mileage car. The front ones are easy.
