Did you get it from Toyota? Bank 1? Toyotas use an A/F Ratio Sensor instead of an O2 Sensor. Toyota also got the P0125 code wrong...it doesn't have anything to do with coolant temp. but does have everything to do with the A/F Ratio Sensor. Finally, check the circuits before condemning the A/F Ratio Sensor...they can be $$$.
