Code C1236 Lincoln Description
The C1236 diagnostic trouble code (DTC) for Lincoln vehicles indicates that the left rear wheel speed sensor input signal is missing. This means that the vehicle's onboard computer is not receiving the necessary data from the left rear wheel speed sensor, which is crucial for the proper functioning of the vehicle's anti-lock braking system (ABS) and traction control system. The wheel speed sensors are responsible for monitoring the speed of each wheel and sending this information to the ABS control module. When the ABS control module detects a discrepancy or loss of signal from a wheel speed sensor, it will trigger the C1236 code.
