Resolved Question:

2001 Jaguar s type 3.0 engine. Has engine code PO420. What do you think?

Hello and welcome to justanswer.com

That code is for the bank 1 cat converter which is the right hand side. The converter will need to be replaced as it has broken down internally. We do need to make sure the engine does not have a missfire from bad coils or a vacuum leak as this can lead to converter failure. Hope this helps and let me know if you have any further questions or concerns.
