Trying to finish up my cat. It has an Autometer Phantom wideband installed in the dash and I need a replacement sensor. Mine has a flat 3 wire plug on it. Looks like a GM connector. Does anyone know the generic replacement for it. I am sure Autometer didn't make it special, but it looks like their replacement sensor has a square plug on it. There are no real identifying markings or numbers on it. Thanks, Joe

if its a 3 wire,,its not a wideband.any ebay 3 wire will work.

Gotcha, thanks

If it is a 3 wire it is totally useless for tuning or to watch on a gauge. It is a narrowband sensor that is used to keep the a/f at 14.7. It has a very narrow a/f voltage range to be used outside of 14.7.

So it's an emissions O2 sensor...

Well shoot. I wonder why they installed it in the boat? I have an Innovative and a Powerdex AFX. Maybe I will install one of them

Autometer calls it a wideband. Good from 6-20AFR. Maybe someone cut off the original plug and installed the 3 wire one. I will investigate

I run the afx in my street car. It is a great unit. That would be worth installing.

I have the AFX, few years old now, never had an issue with the sensor. Nice unit. Mine uses an NTK sensor, not the bosch.

The autometer just has 3 wires all the way to the dash. I will just install my Innovative in its place and keep the AFX for tuning my other stuff. Thanks guys
