Question about 2001 Chevrolet Tahoe
Thanks for using FixYa. If all the o2 sensors were replaced but still the diagnostics says that 2 o2 sensors are bad then I believe they are either not placed properly or have gone bad again. You need to take it back to the service center and tell them to check it as they should do this free of charge.
Please do accept the solution and revert for further assistance.

hen the service engine soon light (Also called the check engine
light) is turned on this is to alert you to the fact that powertrain
control module (computer) has detected a failure somewhere in the
systems it controls, this can be the transmission or the engine or
emission system, there are fault codes set in the modules memory for
these faults. What needs to happen now is to have the powertrain
control module scanned with a special tool called an OBD2 electronic
engine control scanner or a OBD2 code reader. Once the code(s) are
read then you must perform the diagnostics for each code and make the
appropriate repairs based on the findings of the diagnosis that was
performed, this is called doing "Pinpoint" testing.
