Code B1D91 Description

The B1D91 diagnostic trouble code (DTC) indicates an issue with the steering column tilt position sensor circuit being at a low voltage level. This sensor is responsible for detecting the position of the steering column, specifically when it is tilted up or down. When the sensor circuit is reading a low voltage, it can lead to inaccurate readings of the steering column's position, affecting the vehicle's electronic stability control, power steering, and other safety systems. If not addressed promptly, this issue could potentially lead to unsafe driving conditions and diminished vehicle performance.
