Two P0420 Codes? Is this normal?
I have a dp with cat-delete and I went to autozone to get the codes pulled only expecting one... but i Got a P0420 and a P0420 PD...

Just wondering if this is normal because in his little booklet it had a list of other things besides just cat below threshold...

Thanks.

Yes, one is the hard code that set the light off the the other is emission related (PD). So it is possible to have the P420(PD) code without the SES light coming on.
