DIY : changing the Oxygen / O2 sensor on Yaris hatch MANY PICS

[CB900F2]

Hey all..

I decided to check out my Air/Fuel sensor and based on the service manual inspection page(EC-18) From terminals 1>>2 it should read approx. 1.8 to 3.4ohms, mine read 2.8 ohms, but when I check terminals 1>>4 it should read approx. 10K or > ohms, but I read open.. No reading.. I am not throwing any engine code, so its seems odd to me..

Does anyone have a spare sensor they are also measure and see what you get on the 1>>4 terminals?..

I get about 490KM on approx. 38 liters of gas.. I drive pretty hard , and that's about 7.7L per 100KM.. which seems OK...

Any thoughts ?

Thanks guys!

Sorry to resurrect this thread but in the event it helps somebody I also got open readings on pins 1 and 4 for both sensors, new out if the box from denso.
