06 Sonata
Waiting for my Duel EFIE for my 04 Tahoe and getting ready to work on an 06 Sonata. I have learned that the Sonata uses an Air Fuel Ratio sensor with only a grey wire and a white wire. This differs from the regular O2 sensor because it uses "Current" not Volts to send a signal to the computer. Any Ideas on how to override this type of "O2" sensor?

RE: 06 Sonata
look for the red/black wire on the harness side of the front 02 connector and check the voltage to grnd. with engine warmed up and running at 2500 rpm it should jump from around .2v to 1v. mine did on my sonata and mike said we can use an efie on these sensors.
i had wierd readings at first but i found out my ohmmeter was bad.

RE: 06 Sonata
I came from the dealer today and one of the mechanics showed me the two O2 sensors and they only have 2 wires coming out of each. 1 gray and 1 white. I specificly asked which was the signal wire and he said the gray. He also showed me where they snap into the connector by the firewall but I did not look to see what wires were in this connector group. Is this where you are talking about looking for the other wires?

RE: 06 Sonata
you must have a v6 model. my connectors are at the dr side rear of engine compartment connected to a bracket off of the engine by the brake reservoir.

Yes, I do have a V6. I cant believe that they have different O2 sensors between the different engines. Have you had any luck getting more info on adjusting the AFR sensors yet?

Those Ford 4.6 L engines are tough nuts to crack. What have you done so far? How much HHO, i.e. lpm ? Where are you injecting it? Do you have single band or wide band O2 sensors; who's EFIE are you using; what's your electrolyte; do you have any data reflecting changes made and results obtained? I've got a '96 Lincoln along with another poster on this board and we're watching all the F150 results because they're basically the same engine as our "Hotrod" Lincolns.

i have tried a full spectrum of things. pumping abou 3.5 lpm into the vacuum line at rear of TB, i have the fuelsaver circuit board efie set at 380 (i've had it set at all different values), naoh elect. My observations are that the truck is very difficult to predict. The most gain ever was about 3mpg with about 2-2.5 lpm with no efie. But after 100 miles cel came on always, had a bad IAC. Had to change the TB and now no cel but best gain was 1.5 mpg with efie @ .25mv. I am still at the drawing board. I have my results illustrated on another post,http://www.fuel-saver.org/showthread.php?tid=2010&pid=26875#pid26875.

So, back to this thread, is there anyone out there that has had positive results with the 06 sonata?
