p0138 and p0140 error codes

[reaper]

I'm getting these 2 error codes: p0138 and p0140-- no activity from the sensor. Googled it and something about an o2 sensor popped up-- this shows up when there's just constant voltage on the o2 sensor. Easy fix or dealer trip? I haven't had any spare time to diagnose further...

O2 sensor takes second to change. Definitely do it your self

Thanks Art! I changed it out yesterday and I'm good to go. Moab, here I come!
