NTK 23159 Oxygen Sensor

WARNING FIRST : look out for proper NTK green box packaging and actual NTK stamping/marking on the actual sensor. It should be in a sealed bag with manufacture literature inside a green box. The first one u received was in a regular zip lock bag with a sticker on it that says “certified new NTK” and the item did not have proper NTK marking in it, or a plastic protective cover over the sensor end. I returned it because I know Jee Wrangler are very sensitive to oxygen sensors that are not OEM aka NTK brand.ACTUAL PRODUCT REVIEW: The actual NTK sensor works perfectly for a 2005 Jeep Wrangler in the Bank 1 Sensor 2 location. Ignore what Amazon tells you. This is actually the correct part.

Muy práctico

I needed to replace an older Bosch O2 sensor and read that these are the OEM supplier.NIGHT AND DAY DIFFERENCE!!!!My Jeep idles smoother, sounds better while driving and it’s not even close. I had just assumed that my ol’ Jeep was just getting older but it had been running rough and stumbling for years because the Bosch just doesn’t work as well for Chrysler.Anyway, great product. If you are replacing O2s choose the NGK NTK O2 Sensors.

Make sure this is the right one for your vehicle. My vehicle has 4 sensors, I replaced both up stream O2 sensors with this. Worked great. Note: SOME VEHICLES HAVE DIFFERENT O2 SENSORS IN USE, MAKE SURE THIS IS GOOD FOR THE ONES YOU NEED TO REPLACE.

Was the right replacement part. Fit is correct

I had been troubleshooting a check engine light/fault code (P0153) on my 2008 Jeep Grand Cherokee 5.7 Hemi V8 that refused to go away despite having replaced all 4 O2 sensors, checking for exhaust leaks, and flashing the PCM (Computer memory). It took me several months of research to isolate the problem via online forums and expert help websites. I finally came across a blog about the P0153 code in which several of the users had suggested swapping the Bosch Universal O2 sensor out for the original OEM stock O2 sensor (the NTK brand) because of some sort of incompatibility with late model Jeeps. I didn't really understand why this would be an issue until I researched the whole system. It would seem that the Bosch sensors simply don't responde fast enough for the older Jeep computers to recognize them as working properly. I finally broke down and bought 4 of the NTK's to replace the Bosch sensors that I had my local Kwik Lube shop install for me a year prior. The check engine light remained on after the swap so I pulled the battery cables to reset the memory. Unfortunately the light came back on after about 25 miles of driving, but then went off after another 25 miles and hasn't come back on since...I've put about 200 miles on it since the light went out and this is the longest that it's stayed out since I started troubleshooting this bad boy. I'll update this post at a later date if the light stays out for anyone who's having a similar problem's benefit.

Cleared my check engine light.

This product showed up used with stripped out threads and did not even fit my vehicle. This is the second time around that I have gotten an O2 sensor that did not fit my vehicle based on the description.
