My check engine light came on this week so I went to O'Reily and used one of those code readers to see what it was. My car is a 2001 Mercury Cougar.
What does it mean?
What do I check?
What do I replace?
What do I buy?
Kind of late but it looks to me like your car's oxygen sensors (or O
2 sensors) are detecting your exhaust is running rich meaning you're burning too much fuel. I'd look at typical fuel related things like your fuel filter, fuel pump, injectors, stuff like that.
I'm by no means experienced with codes but that's what I get from it. If nothing else go join a message board dealing with this stuff and find out lol.
EDIT: If you do indeed have a Ford:
try here?.
