I took my 2000 Honda Civic EX to AutoZone to get the codes from my check engine light being on. The two codes I got were P0420 & P0131. It mentions the catalytic converter for code P0420, but I changed that last November when the check engine light was on then. When I told the guy at AutoZone this, he said to check the O2 sensor, since it was mentioned in both codes. Any other suggestions?
