O2 Sensor Problems?

[bigairboarder44]

Ok guys, some help would be fantastic right now. I searched (yes, I use this feature extensively) but didn’t come up with anything that was similar to my problem.

So the other day I was driving on an expressway and suddenly my SES light came on. I thought that’s odd and then when I got home I checked everything and it all seemed to be fine. So this morning I went to Autozone and got an OBDII test and four codes came back (however, they were repeats, so only two really).

P0131 – O2 Sensor Circuit Low Voltage Bank 1 Sensor 1
P0132 – O2 Sensor Circuit High Voltage Bank 1 Sensor 1

I thought that was kind of strange..that opposites would show up in the same scan.

And last weekend, I replaced all of the spark plugs and the fuel filter and I did the free ram air mod.

Does that ram air mod have anything to do with the SES codes or am I totally off? Or is my O2 sensor just bad?

Oh and unfortunately, I'm out of town (at my lakehouse) right now and will be for the rest of the weekend, so anything that I have to look at the car about will have to wait till Sunday night.

Thanks for your help
Brandon

Re: O2 Sensor Problems?

Looks like a O2 sensor but without a scanner to show what the output is, no way of telling.

Call me a newb, but what do you mean scanner output

Like HPtuners , has a scanner or any other scanner that scans OBDII to see how much milvolts the O2 is putting out like normal at WOT would be 900's to 940's. If there putting out lower they are probably bad, but if your getting those codes it sounds like time to for a tune up.
