STFT and LTFT should be between -25 to +25. But the sum should be between -10 to +10.
The negative sign shows ECU is reducing fuel as the rich mixture is measured by the O2.
A positive sign shows ECU is adding fuel as the lean mixture is measured by the O2.
Narrow band O2 fluctuates from 0 to 1 volt. But it should be between 0.1 and 0.9.
If it sits on one value for too long, it's dead.

Bhai Jaan kindly yeh video end tak dekh kr btaye k STFT, LTFT, O2, and other value are ok.
My Suzuki Cultus model 2010 gives 15KM/L on Highway with AC and without AC just 16KM/L. Mechanic says each thing is normal. Electrician says O2 not working properly. Fuel Pressure is 40PSi. If there is any abnormality then kindly tell me problem with solution.
Advance Thanks for your precious time and valuable information.
