Code P0606?

Just for info:
A misreading O2 sensor will cause this code.
You replaced one O2 sensor.
What about the other one?
You have two O2 sensors.
One for each bank so if one of those O2's are misreading, it will throw the 606.
I also asked earlier if you can see the impedance on both O2 sensors.
I'm just trying to eliminate a bad O2 here.
Not saying your flash or some other component is throwing the 606 code.

There are plenty of real codes for leaks and o2 sensors. Why is p0606 being associated with o2 anything?

I would replace the other O2 sensor at this point if you find no exhaust leaks around it.
And if the 606 comes back with both 02 sensors replaced, ECU would be the only one left.

I would be more then happy to do some research on your code. I have access to Alldate and Identifix.and seeing as I am a new Lexus owner I suppose it would be in my own best interests to look into it anyway. 😉 P0606

The gist of it. Its either a/f sensor, wiring or ECM. Keep in mind many manufactures require an OE sensor to fix the problem. Aftermarket will not work.
Pictures are clear on my phone!?!? Lol
Hey CL,
recently I had a check engine light for an o2 sensor and p0606. I just got the sensor changed and the o2 sensor codes went away but now I have a persistent P0606 PCM error/fault. Anybody experience this code with no other codes?
i thought after replacing the o2 sensor the code would go away as well but it didn't. I read that it may be a bad gas cap but wouldn't I can some evap code? The car runs and drives like normal. Is it normal to replace the ECU in our cars?I also read that there may be an invisible P0607 code that may be there due to aftermarket tail lights shorting? Do I need to use techstream to do some sort of hard reset that a normal obd scanner tool can't do? Tried a few methods removing some fuses to reset the ecu and also taking off the battery terminal to try and reset it but the light comes back on. Is there a feature that if an error code triggers too many times that it stays in the system until you do some sort of special reset?
Any help would be appreciated, Thanks

Thanks a lot Shawn Bailey for the helpful insight! Your pictures are clear thanks!
EDIT: Problem finally solved, system picked up the other sensor that I didn't replace was acting faulty, replaced and no more engine codes p0606

guys this is an old post I know but i have a question, anyone of you flashed away the first set of o2 sensors and cats? I am not in the US, anyways I am asking here because ou guys do more stuff with the IS than the LS. So the issue I am having is 1st set of cat delete (LS has 2) and 1st set of o2 sensors. The cat has been removed.. the 02 sensors have not. they are still attached. I has the ECU flashed supposedly to delete as stated before and it was running ok, then I start getting P0606 codes once in a while with check engine light but it comes and goes, it will even reset itself sometimes without me having to clear the code and CEL. If the faulty sensors remaining in can cause a problem even if flashed properly I need to get them out.
So my question is could this be because the 02 sensors are still physically plugged in ? And if these sensors have been so called flashed out, should I be able to see these sensor values on a ODB reader? if the answer is no then I know the ECU was not flashed properly...
Thanks guys
