So I have a 2005 3.7 Durango and my check engine light is on. Get code P0058, end up replacing the oxygen sensor (with NGK brand sensor), clear the codes. Drive the vehicle home no problem, next morning light comes back on, same code. Tested the the sensor on Ohmmeter and was/is in working order. I am stumped. Any help or ideas are much appreciated here!

 

how hard was it to access where it plugged in,i would use an poem O2 sensor

 

It is relatively easy to access and change the sensor. I will look into that brand sensor, as everything I had found online had previously suggested NGK. Bought a new (and got it programmed) PCM to pop in this weekend, to see if this fixes the issue. Other things I have done in the meantime to help troubleshoot this issue include checking the high and low voltage on all sensors to insure they are within range, checking to make sure there are no exhaust leaks..... Only other thing I have left beyond replacing the PCM is tracing down every wire to and from the O2 sensor and checking for any issues. Will update.

 

Yeah, just realized you probably meant to type OEM, and auto correct got to you, gets me every time.
