Note: Most automotive sensors use 0.5-4.5V range on 5V reference. Voltages outside this range indicate open/short circuit faults (OBD diagnostics).

Reference

ADC Steps = 2^bits Step Voltage = V_ref / Steps Min Count = (V_sensor_min / V_ref) × Steps Max Count = (V_sensor_max / V_ref) × Steps Usable Steps = Max Count − Min Count
