Was told to replace O2 sensors, before I did that I called my mechanic (Not a service centre rip off) he told me even if replacing the sensors the powertrain check warning might not even stop after they are replaced. I've been trying to find a reset trick for it, but found nothing as of yet.

Hello
The
Engine and Automatic Transmission (not applicable to manual
transmissions) in this vehicles drive train are fully electronically
controlled by a computer called the PCM and TCM (Power Train Control
Module, Transmission Control Module). When a problem like this or
other drive-ability related problems occurs the computer stores a
record of the problem (there are of course some exceptions to this,
like the fuel pump, engine coolant temperature sensor and MAF sensor
for instance) in the form of a fault code in its memory, to read
these fault codes you must have the systems memory scanned with a
special tool. Once the fault code(s) are read you then must perform
the appropriate diagnostic testing to find and resolve the problem(s)
DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED
THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT
MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for
correct spec for your make and engine type.
