Hi Peter, your code and other checks do indicate a sensor fault, however the waveforms posted suggest to me a catalyst fault. I have noticed that the downstream sensor picks up on cats sooner than an emissions test does. Also, if this is like some other Toyotas, with two stud HO2 sensor fixings, check studs and gaskets for air ingress. Cheers, Tom
