Pinpoint Test T: LFC 49/DTC C1948 - Seat Track Position Sensor Circuit Resistance Out Of Range: Notes
WARNING: This page is about a different car, the 2005 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Due to the seat track position sensor being a hall-effect type sensor, this pinpoint test will be diagnosing a current out of range fault instead of the current DTC definition for a resistance out of range fault.
