I have a 2007 srx with a 3.6. A p0160 popped up so I replaced the O2 sensor. This did not fix the problem. While viewing the pid with a scanner it remains a stable .455. I ohmed out all of the wiring and it seems good. I ended up putting the 2 signal wires right at the plug for the ecm and connecting an O2 sensor while hitting it with a torch. Still no change. I did the same test with b1s2 and I can see the signal coming across. After soldering the connections back together and driving I see an occasional change to maybe .5 but mostly it stays at or around .455. I feel like I have a bad ecm input but would like anyone else's opinion before I spend the money to replace it. Thank you in advance.
