The car is confused about which way the back left wheel is turning.
The vehicle's computer is receiving a signal from the left rear wheel speed sensor that doesn't make sense, indicating a possible issue with the sensor or its readings.
The C1232 code is triggered when the vehicle's control module detects an implausible signal from the left rear wheel speed sensor regarding the direction of rotation. This could be due to a faulty sensor, wiring issues, or mechanical problems affecting the wheel's rotation.
