bought a 2000 honda accord check engine light came on code p1166 and p116 help

P1166 is a failure in the heater circuit in the Air/Fuel Ratio Sensor. This code can come up for several different things however it is most commonly due to a bad Air/Fuel Ratio Sensor. There are several different companies that make a sensor for that vehicle. We try to stay away from universal parts, we try to only use a direct fit part by the origional part manufacturer. As long as the part is made for your application you should be able to use it. I hope this helps!! Happy Holidays!!!
