I'm having the same issue on a JDM EVO9 GT ECU using the tephra 88591715 ROM, Any help to remove the PO462 CEL please

 

Can I suggest you guys try running the 8857 v7 rom.
This seems to run very well on the AUDM and EDM Evo9s and you wont loose the temp sensor function although on the 8857 the code thinks this is an intake manifold sensor not tranny.
No matter, it still works fine for either.
