My obd monitor giving out oxygen sensor codes.Goi g to replace maf again using dealership product. Was replaced previously but not factory product. Running well now.Should I clear codes on vehicle first by disconnecting battery and putting positive n negative together for ten seconds to reboot.
it’ll either clear itself or you can go ahead and do that. sure, what could go wrong.
i personally suggest using an OBD tool to clear it up if you have one.
I guess the obd can be trusted. Mines a cheapy
