Review on 🚙 A27678X O2 Sensor Set for Jeep Cherokee Grand Cherokee Wrangler 4.0L - Upstream and Downstream, Sensor 1 and Sensor 2 - 234-4076, 234-4078 by Patrick Hamman

I have found that some Dodge vehicles listed as compliant with this part do not require a second sensor. My mom's old Dodge Durango only has one oxygen sensor, not two. I thought I was missing something as I found and installed one but couldn't find the other, but no, some models use two and some don't depending on the finish and when exactly it was made (and in which condition it was). did). Per). However, I could have easily found this before ordering as I noticed many separate packages that also fit this model (makes sense). So this double pack has exactly what you need, but you just have an extra one you don't have. Should I return it or something? No; The quality is good enough that I don't mind eating something at $20 for an extra that I won't be using. It was part of a rebuild of my mom's old 2000 Durango that had done just over 234,000 miles by check engine light. showed up a few months ago. The check engine light is gone (not because of this part) and I hope it stays that way for another 234,000 miles.
