This code means there's a problem with the car's system that checks if there's enough washer fluid to clean the windshield. It's like a sensor that tells you when you need to add more washer fluid.
The B0131 code is triggered when the vehicle's control module detects an issue with the circuit responsible for monitoring the washer fluid level sensor.
The B0131 code indicates a malfunction in the control circuit of the washer fluid sensor. This sensor is part of the vehicle's body control module (BCM) and is responsible for detecting the level of washer fluid in the reservoir. If the circuit is open, shorted, or has poor connectivity, the code is set.
