Question about 2002 Chevrolet S-10

1 Answer

I have a 2002 Chevy S-10 Crew cab 4wd LS. I was

I have a 2002 Chevy S-10 Crew cab 4wd LS. I was on the high way traveling approx. 55-60 mph and as I started to go up a hill, I lost some engine power and was forced to drive up the remainder of the hill at 35 mph with my hazard lights on. Right then is when my service engine soon light came on. I went to Auto-Zone where they plugged a little gadget up to my truck to tell why my service engine light came on and it came back as a code 420. My question is what are some of the culprits responsible for having my O2 sensor read low oxygen?

P0420 is Catalyst System Efficiency Below Threshold (Bank 1) o2 sensors reading are used to check the cat if the cat is plugged you will lose power o2 sensor send a voltage signal to the computer 0 to 1 volts The o2 upstream of the cat should switch back and forth from 0 to 1 volts, average .450v if voltage stays high engine is running rich (low oxygen) if voltage stays low engine is lean (lots of oxygen) cats have a 8-year 80000-mile warranty
