So I have a 97 thunderbird LX with the 4.6l, and I'm very very new to this car. The purchase opportunity sorta fell into my lap, so I have been just getting used to things.
I'm running Forscan on a BAFX obd2 Bluetooth device, just logging data and getting things set.
I noticed today that my Bank 1 Sensor 2 (B1S2) seems to read low, if any voltage until the car is at operating temp. Then proceeds to really only read during moderate or higher engine load.
By contrast B2S2 seems to read more consistently throughout all operation, having less reading when low load is on the motor, but nowhere near as low as B1S2.
Are the voltage patterns in these sensors supposed to differ so greatly?
Below are my screenshots. They are in order as Bank 1 Sensor 1, B1S2, B2S1, and B2S2 respectively
