Honda/NTK O2 sensor (redux)

[Glenn & Debbie Woodhouse]

Barry and Dan,

I bought my sensor through NAPA with a direct cross to the Honda p/n.  There
was no Bosch cross and that concerns me a bit with the www.thepartsbin.com
part that Barry referenced.  In fact I do not believe that Bosch builds an
ion pumping based sensor, which produces a variable current output, so how
can there be a cross?  Bosch's wideband sensor (the LSM11) produces a
variable voltage output with exhaust temp. correction performed
programatically using a 3D lookup table in the ECM based on change in sensor
resistance (temp.).  Is it possible that NTK has licensed Bosch to build
this sensor as well?  I can't definitively say that I know that Bosch
doesn't have other WB technology.  On the www.thepartsbin.com site if you
drill down through the particular vehicle menus, the California version of
the VX is a NTK sensor ($94.78) versus the non-Cal which is a Bosch.

Dan, what you are calling a connector in the middle of the harness is a
rubber grommet, used for securing the wiring to a bracket or such in the
Civic.  If you know what vehicle it came out of or have a p/n you can call
NTK tech support in Michigan, (248) 926-6900, for further information on
this sensors capabilities.  I have received very straight answers from John
McQuarry (not sure of spelling on last name), unlike the Japanese
counterparts at NTK.  The fact that your sensor does not have a calibration
resistor is suspicious.

Good luck, Glenn.

I realize that only the Civic VX has the correct sensor, and all other
Civics don't.  The sensor I have terminates into two connectors, a
three pin and a two pin.  The sensor does look similar to the one
pictured at FJO-Enterprises.  There is the same mid-connector (in fact
two of them), and then it goes to the two connectors and a bracket.
The website claims the hex size is 22mm and the thread size is 18x1.5mm.
My sensor seems to be smaller than that.  I'm not sure about either
size, but the hex nut is clearly smaller than my 22mm O2 wrench socket.

I guess my real question is, is it possible that I could have a WB O2
sensor with a smaller hex nut and two connectors instead of the
standard stuff.  Are there any 5-wire NTK sensors which aren't wideband?
If there aren't, it pretty much answers whether this is wideband or
not.

The sensor is still available @ the "old" price - $117 - bought mine a
couple of months back, but the price is unchanges, I just checked.
