Remote Start stopped working

[Osprey]

It is code P2254: O2 Sensor Negative Current Control Circuit/Open Bank 2 Sensor 1.

Any idea how to fix. Did not see anything online but must be a common O2 issue

I'd be willing to bet that the fix will be to replace the O2 sensor

I just had my fuel pump control module replaced and the remote start has been solid ever since then. Before it was replaced it was hit or miss if it would work or not.

Mine turned out to be dying remote battery.

I thought it was strange too, but when hunting I run an cb antenna cable out through slider, and remote start wouldn't work (Just got horn honk). As soon as I pulled cable into cab and closed slider all the way, boom, remote start works again.
