Hello and welcome to JustAnswer!

This code sets when the engine controller determines that the right bank upstream oxygen sensor signal is incorrect as opposed to the downstream sensor. This could be the upstream sensor, an exhaust leak, or it may be caused by the aftermarket parts. Changing the flow rate and volume of the exhaust upstream of the converter and sensors can cause codes to set.

Where did the replacement oxygen sensors come from, and which ones were replaced?
