What are the following codes telling me?

I have searched the forum and found nothing on these codes.

P0146 - HO2S Circuit Insufficient Activity Bank 1 Sensor 3

P0452 - Evaporative Emission Control System Pressure Sensor Low Input

The blazer is running/shifting fine.

Well, you must not have looked in the Diagnostic Trouble Codes (DTCs) section, because they are both there.

OK, I"ll check it out!!

Sorry.

Didn't know the DTC section was there, just plugged the codes into your search engine and nothing turned up.

Still learning your forum.
