From a DodgeRam forum....."Try unscrewing the O2 sensor that used to be located downstream of the catalytic converter and tie it off to the frame rail so it's exposed to fresh air. Then buy an 18mm plug from most parts shops to plug the O2 bung on the pipe. The downstream O2 sensor is typically configured for Catalytic Converter efficiency - as long as the air it reads is "cleaner" than the upstream O2 sensor, then the computer assumes the cat is working well and the code won't appear."
