2002 Honda CRV p1166 p1167 Sign In

About a week ago I got into my 2002 Honda CRV (57k miles), and the check engine light came on. I went to autozone to have them pull the codes for me and they told me it was p1166 and p1167. From this I was assuming that there was a problem with my primary O2 sensor. As I am low on money, I was hoping to wait to save up a bit before I repaired this. I read on the forums that my gas mileage would be reduced and my catalyctic converter would be running harder than normal, but other than that the car is still safe to drive. Out of curiosity during this time I tracked my gas mileage, and during this previous week my gas mileage has not reduced at all. So, could the problem actually be something different than the O2 sensor? Any other suggestions or recommendations would be great. Thank you very much for your help in advance!

Those codes are for a heater problem for the sensor. It's most likely a burnt out heater element in the sensor. That causes the sensor not to come up to temperature as quickly as it should and will mainly effect things during warm up.

Both those codes indicate there is a problem in the heater circuit for your a/f sensor. An O2 sensor & air/fuel sensor basically do the same job and construction is very similar but the way they work is totally different, one is a narrow band sensor & the other a wide band sensor..

With any fuel control input, it is important that it's accurate. Your problem is in the heater circuit. This is what it implies, a heater for the a/f sensor. Both use heaters for peak efficiency. While you may not notice it your mpg, it should be taken care of as soon as possible. If it starts throwing P0171 or P0172 codes as well then you are probably damaging your converter.

While this isn't as critical as driving an overheating problem it still needs to be addressed...........

So essentially the entire O2 sensor has to be replaced still?

What entire? It's just a sensor. It doesn't come apart.

You're right, I guess I meant to say that the solution to my problem still would be to replace the O2 sensor. Sorry about that, and thanks for the help

The correct procedure would to verify power and ground arriving at the sensor first. You can also test the resistance in the heater in the sensor too. If it's burnt out it will probably read open circuit. The heater wires will be 2 the same color, usually black or white.
