Sensor: A device that detects or measures a physical property and records, indicates, or otherwise responds to it.
Reservoir: A storage space for fluids in a vehicle, such as brake fluid or windshield washer fluid.
• B011C
• B011E
This code means that the car's computer has detected a problem with a sensor that checks the level of fluid in a reservoir, like brake fluid or windshield washer fluid.
The vehicle's control module has detected an issue with the sensor that monitors the fluid level in a specific reservoir.
The B011D code indicates a malfunction with the Fluid Reservoir Level Sensor B circuit. This sensor is responsible for monitoring the fluid level in a reservoir and sending this information to the vehicle's computer. If the sensor is faulty or the circuit is open/shorted, the code will be triggered.
• Check the fluid level in the reservoir.
• Inspect the wiring and connectors for damage.
• Test the fluid level sensor for proper operation.
• Refill the reservoir if the fluid level is low.
• Repair or replace damaged wiring or connectors.
• Replace the faulty fluid level sensor.
• Multimeter
• Screwdriver set
• OBD-II scanner
