Hey everyone I have a 2002 Honda Civic EX, and I am soon to replace my factory O2 sensor with the NTK L1K1 Wideband O2 sensor.

Now, my factory O2 sensor's are the four wire ones, so I have a few questions regarding my set-up...

Currently, I have a V-AFC2 and an Autometer Air/Fuel Gauge...
Can all this be working in conjunction together?

I heard that the Air/Fuel Gauge is unreliable in it's readings, but then I heard if you replace the O2 sensor with a wideband it'll work correctly...

How would I hook it up, considering the Wideband one has 5 wires and my stock one has 4?

And also, would I replace the first O2 sensor on the header, or the second one after the cat? Thanks everyone!

Come on guys....

 

Can't help with much, but the first 02 sensor is what you replace. I have the Tehcedge kit and it has a narrowband output for the cars signal.

 

No,

This will not work. A wideband needs a fairly sophisticated controller to get it to work. If you try it your way, you have just found a way to quickly dispose of a WB sensor. A WB controller CAN output a voltage to simulate a regular O2 sensor, but the WB (5-wire) sensor is a very different animal altogether, it just looks similar to a narrow band O2. A regular O2 sensor just outputs a voltage, bigger than 0.45V for rich, less than 0.45V for lean. All it CAN tell you wether your rich or lean, and that is ALL it can tell you and is designed to do. The only correct AFR number on an AFR meter using a regular O2 sensor is 14.7. All other numbers are just paint on the meter face.

 

yup, some thing else is that you can get o2 sensors with displays on them to tune you car correctly. like the other guy said a lot of them have 0-1v outputs to kinda fool the ecm, since the wideband uses amperage.

He's right. Look into the Techedge or PLX devices or Innovative wideband setups.

 

where can one buy a good wideband o2 sensor? i'm boosting soon and was thinking of investing in one.

You need more than just the sensor.
