O2 sensor question
I'm chasing a couple of codes regarding the O2 sensors. The descriptions are:
Lambda sensor aging tv bank 2
Drive cycle C
Lambda sensor aging tp bank 2
Drive cycle C
So from my research, this means they are basically slow to respond, am I correct in this mode of thought? Does "tv" and "tp" refer to position, as in upstream and downstream, or something different?
Thanks for any wisdom provided,
Wesley

Thanks for the advice! Since it's only on bank 2, I've looked and listened for exhaust leaks on that bank, with nothing found. If it were a part of the EVAP system, wouldn't I have those codes on both banks?
Plus, does any one know what the "tv" and "tp" refer to? I can graph the sensors with my scanner tool to verify, but I'm really curious as to what those two designations mean.
Thanks again for all the wisdom!

Well you can buy the o2 sensor cheapest place is rock auto however I still strongly advise what I said above. Smoke test the vaccum system and exhaust and replace your fuel purge valve. All cheap solutions

I have been chasing a similar issue. I have replaced the Hyundai purge valve a few months ago, i know it could still be bad.
I sprayed carb cleaner all over, the junctions, seals, etc, no movement.
My codes are P0101, P0172, P0175
Will try to find someone to do a smoke test, there are instructions for a home version, but at this point for the money I would rather have it done.

Check mass airflow sensor (do not spray with contact cleaner, use mass airflow sensor cleaner). Then check coolant temp sender, and check to see if thermostat is stuck open. Your issues sound like MAF sensor issues, but can sometimes be mid-diagnosed and related to cooling system.

thanks for response, I have cleaned the maf, no luck. I have ordered a new MAF this week, Bosch, will see if that's my fix.
the o2 sensors appear to work by all verything I can read.
