No reading.. I am not throwing any engine code, so its seems odd to me..

Does anyone have a spare sensor they can 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!
