went to test drive a used I4 Santa Fe. plugged in a bluetooth odb2 scanner, drove it in different speed. My android odb2 app (Torque) shows that bank1 primary O2 sensor is within normal range (fluctuates bwten .1 and .8 volts) , and LTFT1 fluctuates bwtn some neg and postive %. But STFT1 has no data at all. Does this indicate any issue with the vehicle?
When do the same test on my own two vehicles, all 3 have data.
