Code 0011 (via dsmlink)

[chavez408]

So dsmlink is telling me that my front o2 circuit is malfunctioning. Is the dsmlink pretty accurate on reading codes?

 

[1992awdlaser]

Dsmlink is 100% accurate when reading codes.

so should i just replace that o2 completely?

 

[1992awdlaser]

Could be the sensor or it could be the wiring for the sensor. If the sensor has not been replaced then I would just replace it. If that doesn't fix the problem something is wrong with the wiring.

Oh ok well Ill just replace it when I get my new 02 dump in the mail. Ill replace the sensor with it. Autozone should carry them, I hope.

You probably won't find an OEM sensor at AutoZone and I wouldn't recommend getting one of the universal ones. If you go universal, you'll have to hack the crap out of the harness, which isn't fun.

Check out Spark plug, Spark plug wire, spark plug gap, spark plug cross reference and ignition wires at Sparkplugs.com if you want a cheaper than dealer prices OEM sensor.

as every one says, stay away from uni o2's. The old owner of mine, used one, i had a mess for my rear, but got a good harness from a junk yard. I use these guys.http://www.oxygensensors.com they have good prices and such.

What about machv's denson (sp?) o2 sensors? I hear nothing but great things about them. Will a faulty o2 sensor make me run rich? I see alot of knock in my logs as well.

Are these two the same o2 sensor? Big price difference.

Denso Oxygen Sensor

A bad o2 sensor will make you run really rich and waste gas. The voltage of the sensor will be low which indicates a lean condition. And the ecu throws a lot of fuel into the engine to make sure it doesn't go lean. Denso makes good parts.

I've recently had the same code appear after I installed DSMlink on my car. I thought that the wiring going into the ECU was loose, since I was down there cleaning the rat's nest of wires, so I checked it, and it was fine, which leads me to believe that the O2 sensor is failing. Do you guys recommend going with the Denso or the NGK offered on Sparkplugs.com? I trust both brands and are the same price, but I want to know which one is recommended by DSMtuners.

To the OP, as 1992awdlaser has stated, when the O2 sensor is failing, the LTFT's will start to go haywire since the voltage reading will fluctuate wildly and the ECU will compensate by adding lots of fuel to be safe, correct me if I'm wrong.

If I remember correctly, the OEM is NGK. It really won't matter which one you get as long as they are listed as OEM replacement.
