Right, the ECU doesn't know the problem is fixed until you reset it. I practically guarantee this is the issue.

Just reset the ecu. Here's how:
pull that fuse and reinstall it. You will lose your presets on your radio.

Did you replace it with a craptermaket brand or OEM? Check your fuses and make sure they are all good, under the dash too. Then take the top off your ECU and smell it, had a o2 heater code for almost a year before i narrowed it down to the bad ECU. Welding exhaust with the battery connected it not a good idea....

Also there is a TSB for the main harness that runs underneatht the intake manifold, over time the harness rubs against the manifold bracket and will cause the o2 wires to short out. Fuse 15 will be blow under the dash and the ECU smell like "burnt" if it is bad. Correction: Remove intake manifold bracket(can be a pain in the 4ss) and fix any frayed wires. Check the ecu. If all is replaced and well, reset the ECU and pray......pray.
