2000 Mazda MPV oxygen sensor location
Wayne’s question:
A simple question. Where is the bank one number one oxygen sensor on my 2000 Mazda MPV?”
Answer:
That sensor is the one on the firewall side of the engine right off the exhaust manifold, before the catalytic converter. Bank one on all cars is always the side where the number one cylinder of the engine is. And in your Mazda, that’s the back side by the firewall.
