hello
I need help! I have a 2004 Mazda 6 V6 and having issues with the traction
control coming on and losing acceleration. Have to pull over and put in
park turn off car and turn back on and start driving again. Then it will
happen again. I have to repeat several times before it will run fine.
Someone tested it and showing throttle body not opening making clicking
noise. I was told before it was a O2 sensor but now I was shown the
throttle body wasn't open correctly. I seen a video where it showed the
battery could cause these issues. I was wanting your views on what it may
be from what I described happening to my car. I hope you can help. Maybe
have a video on it. Thanks Paula

+Paula Best As s first step - Look up my video "Fix your Mazda 3 Stalling running Rough" - and do this procedure on your car - it won't hurt it and all you're doing is letting it idle by itself in the driveway to reset the computer

I'm curious why you replaced the bank 2 sensor 2. I'm having an issue with
the long term fuel trim on my Dakota with 4.7L.

+timarc124 it had three codes all indicating the downstream o2 wasn't indicating correctly - once replaced and driven for a while it seems everything is now normal

Could it to do with heat. A rich condition would cause the heating element
to cool and a lean condition would cause the heating element to warm. By
changing the ratio between HC and O2 the heating element will either get
hotter or cooler, consequently sending higher or lower voltage through the
signal wire to the PCM???? The sensor is not taking a sample of the
exhaust gas like an eye dropper. Just asking.

+Ed Waggoner Sr. The electrochemical reaction cannot take place below 600F. The lean/rich response is independent of temperature once the nernst reaction is activated.Further we indirectly eliminated any possibility of temperature having effect via the induction of argon. If there was temperature reaction we would have seen response accordingly since the decompressed argon is very cold.

With all respect, why then is the O2 sensor heated to 600 degrees? Could it be that what you are dealing with is a thermistor operating in a narrow range around a base voltage at 600 degrees? More fuel = cooler; more air = hotter?

+Ed Waggoner Sr. (Papatch) Good thinking but heat has nothing to do with it.

I am still confused as to how the o2 sensor returns an oscillation. Is it
because of the 4 stroke process of the engine in which the exhaust exits in
pulses?

see my video "secret of engine diagnosis- fuel trims" and it is explained.

I think a better term for this would be an ion potential sensor. Regardless
of the material, it senses a difference in ion potential on each side of
the electrode . So really any material you introduce will affect the
voltage because it will either dilute or concentrate charge on the exhaust
side.

+nicholas elias maybe that would change the amount of free oxygen

+nicholas elias the octane rating correlates to the reactivity of the gas with oxygen

+nicholas elias im curious about what would happen if you introduce a different octane gas into the picture and see if the values change

+nicholas elias i wonder if the reason why the argon had no effect is because it does not react with any of the gases. Also propane or any gas that would react with oxygen will change the amount of ions. So i think that reactivity plays a huge role as well

After seeing the results of the argon that did surprise me. Im thinking it does have to do with ionization

could this experiment be done with wideband o2 sensor? Or it will read
normally not being aware of the added inert gas, and just read a/f ratio?

+Oros Criss Yes it could but that's exactly what we're doing with the O2 sensor anyway.
