This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is having trouble reading how much fluid is in a certain reservoir, like the one for windshield wiper fluid or coolant.
The vehicle's control module has detected an issue with the fluid level sensor in a specific reservoir, which is responsible for monitoring the fluid level.
The B011C code indicates a malfunction with the Fluid Reservoir Level Sensor A. This sensor is used to measure the amount of fluid in a reservoir and send this information to the vehicle's control module. If the sensor is not working correctly, it may send inaccurate data or no data at all, triggering the code.
• Warning light on the dashboard
• Inaccurate fluid level readings
• Fluid level warning messages
• Faulty fluid reservoir level sensor
• Damaged wiring or connectors
• Low fluid level in the reservoir
OBD-II: On-Board Diagnostics, a system for self-diagnosing and reporting vehicle issues.
Sensor: A device that detects or measures a physical property and records, indicates, or otherwise responds to it.
• Check the fluid level in the reservoir.
• Inspect the wiring and connectors for damage.
• Test the fluid reservoir 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 reservoir level sensor.
• Multimeter
• Screwdriver set
• OBD-II scanner

Moderate
• Toyota Camry
• Honda Accord
• Ford Focus
• Regularly check fluid levels.
• Inspect wiring and connectors periodically.
• Replace sensors at recommended intervals.
Sensor Issue
• Check fluid levels regularly to prevent sensor issues.
• Address warning lights promptly to avoid further damage.
Check with the vehicle manufacturer for warranty coverage on sensor-related issues.
This code has been reported more frequently in vehicles with high mileage or those that are not regularly maintained.
Moderate – Should be addressed soon to ensure accurate fluid level monitoring.
Ignoring this code may lead to inaccurate fluid level readings, which can affect vehicle safety and performance.
• Vehicle ignition on
• Fluid reservoir filled to recommended level
The fluid reservoir level sensor is typically located in or near the fluid reservoir, such as the windshield washer fluid tank or coolant reservoir.
Q: Can I drive with a B011C code?
A: Yes, but it's recommended to fix the issue soon to avoid inaccurate fluid level readings.
Q: How do I reset the B011C code?
A: After addressing the issue, use an OBD-II scanner to clear the code.
