I have a 2001 Toyota Camry 4cyl and recently ck eng light came on. The obdII code was p1135 which indicated a/f sensor(O2) bank 1/sensor 1. Disc sensor and took ohm reading,result was O. I replaced O2 with new one, ohm reading was 0.4. Hooked sensor back up, cleared code and shut light.When I started the engine light was out but after a minute it came back on.Rechecked O2 with same results and then checked female connector end with key on and eng off, slots where black leads go read 8 volts one side and 50+ on the other.
