Asked by maddnnes Sep 24, 2016 at 01:11 PM about the Chevrolet S-10

Question type: Maintenance & Repair

I went and got a e-test today and failed. I was woundering if anyone can make sence of it : Under Systems Monitored it says Misfire (Ready) Fuel system (Ready) Comprehensive Components (Ready) Catalyst (Not Ready) Evapoative System (Not Ready) Oxygen Sensor (Ready) Oxygen Sensor Heater (Not Ready)?? That is what i got back from them.I asked what i could do to help it pass, they said to bring it back the next day but run it for a half hour to an hour?? I get that the engine should be hot but that can't be the only reson that made it fail. I'm thinking one or more of the o2 sensors should be change but which ones??? Totally confused hope someone can help

I would change them all if you have the money, that way at least they are all the same age and check the cat. But also there are other issues that can show as a o2 failure like vacuum leaks, fouled plugs Or plug wires, Throttle body & injectors may need cleaned or rebuilt and the sensors too or tested prior to replacing a o2 sensor as it could be wasted money, even a very dirty air filter.
