Question about 2000 Mazda MPV
One sensor was bad but i decided to replace all but it shows that one is bad . Had it replaced again but the light came back on again
Oxygen sensors are only indicatores of oxygen in the exhaust, You could have an exhaust leak and the oxygen in the exhaust is reading to lean, that will give you an O2 code. Did you have the codes erased also. sounds like you have a too lean or to rich situation or maybe an egr valve malfunction. I hope this helps you
