hi Guys, I just joined this forum today.
I've been working on my Mazda 6 3.0L with code P0051 and P0154, I just replaced my O2 sensor front ones, the codes showed HO2S (LF) or (RF), either a low circuit on bank 2 sensor 1 (p0051) and no activity on circuit (p0154). Do LF and RF meant Front left and Front Right, O2 sensors? (if so, I just replaced them, but still gave me the same CEL code after Drive testing the car for 40 Km). Or do i have to clear the error code?
Please help or some advice will be appreciated!
