Engine Code - P0131 - Oxygen Sensor

Hi all,

Has anyone received this code on their car before? I just received the code...the definition looks to be (Front Heated Oxygen Sensor Low Voltage).

I'm obviously assuming this is the o2 near the header? I have a 00 sir.

What are the usual causes of this error? Bad wiring? Bad sensor? What would be the list of the things to first check and replace? I heard aftermarket O2's are not good for Hondas..what's recommended?

Thanks much

Usually it's a bad oxygen sensor. I'd get a diagnosis done before replacement of the item.

Get a labscope and scope out your primary oxygen sensor.

I'll look in to that. I'm wondering though..if I clear the engine light code and it doesn't come back on again, can I safely assume that the error was possibly faulty? Thanks

Well.. it may take awhile for the code to be tripped again. It takes a lot for the MIL to actually illuminate on the cluster. The monitor has to run several tests at ideal driving conditions before it even sets the code. So depending on your driving habits, it may not come back on for 2 weeks or so, personally I would just get a diagnosis.

The light will probably eventually come on, it just doesn't come on from one freak incident, or one lean condition. It has to fail several times before the light is illuminated. So it is safe to say that there definitely is a problem.

But, you can clear the code and wait and see if it comes back on. Since you got the p0131 code I assume you have a code reader? Try hooking that up in a week and see if there are any pending codes (codes that haven't fully been set yet). If you see absolutely nothing for a month or so it may of been caused by something out of the ordinary (bad tank of gas, weak connection, etc)
