02 Extender

Will an 02 extender work with the Toyota Wide Range Air Fuel Sensor. It looks just like a typical 02 sensor but works different.

Works with an 2000 tundra 4 wire o2 sensor

jimbo40 you say works w/'00 toyota 4 wire wideband . what engine do you have the 3.4L ? which extender are you using and what results are you getting? what cell design ? I have an '00 toy pre-runner w/3.4L w/4 wire wideband they actually call it an AFR but mines located pre-cat in the manifold like an oxy sensor ,yours? what electronics are you running ?
thanx

Magdrive 11a brick generator.
2000 tundra 4.7 , 18mm pre cat o2 sensors with extenders I made from anti fouling spark plug adapters. No electronics

Scanguage 2 shows 15.8 mpg up 13.2 mpg
Tank of fuel 317 miles now 400 miles per tank
Still have very good power.

Oxy extenders are my next move.

But first, Anybody try simply disconecting the plug-in to the sensors? You would get a check engine light but.....?

Most vehicles, if they lose the O2 sensor signal, will go in to what is called "limp home" mode. This is not going to help you out. By design, the ECM will send an extra rich air/fuel mixture through the engine until the problem is fixed.

I did. I lost about 3 mpg, my engine felt sluggish and it ran rough.

I have a 94 nissan pickup 2.4L I-4 2wd

BTW this was with no HHO. I was thinking about trying this with HHO. In theory I believe it should work to a certain extend because you will be using less pedal but you will need to replace more gas due to the fact that the engine runs richer.
