I just checked the code and got a 41( 4 long flashes and 1 short). Someone told me that it's the O2 sensor and it's probably the heated element part on it that's bad.
First, is a 41 a bad o2 sensor and second, how hard is it to replace?
How long can you drive with a bad 02 sensor?

 

Primary 02 sensor heater=41. It would be nice if you could test it, before buying a new one. I hear they can be a bitch to remove (I think they make special tools for removing them). I'm almost tired of saying this, but a helm service manual is your best friend (if you have basic tools, and are mechanically inclined). Haynes and Chilton manuals are a lot cheaper, but have less details and information. You make the call. In my opinion, you are downgrading Honda's reputable reliability, if you use anything other than oem parts.

 

Your info is correct the code indicates the heater part of the sensor is bad; you can drive a long time with the sensor heater bad, but you'll suffer fuel usage because the ECU is running in a default mode.

 

Here ya go....thank me later.....I only wish I could find one for a 99 Accord.
This is legit becasue it was put up by a Honda UK website. They put up the manuals that they discontinued. Enjoy!!!

Go under "fuel and emissions" and select whether your car is fuel injected or carbed.

 

Thanks for that link. Next question: Where exactly is the under hood relay box?
Obviously, it's under the hood but where exactly?
This is my G/f car so I don't know squat about Hondas. I'm a mustang guy myself.

 

Oh...about how much is an 02 sensor from Honda?
