Fluid Reservoir Level Sensor B

Where it lives

For B011D, the part to look at first is the sensor named here.

Check these first

• The fluid reservoir level sensor B is stuck or failed
• An open or short in the sensor B signal circuit
• Water in the sensor B connector
• The reservoir the sensor B monitors is low on fluid

What to do next

1. Top off the reservoir the sensor B monitors
2. Read the sensor B level with a scan tool
3. Inspect the sensor B connector for water
4. Test the sensor B signal circuit for opens and shorts
5. Replace the fluid reservoir level sensor B if the reading is wrong
6. Clear the code and retest
