Fluid Reservoir Level Sensor A

Where it lives

For B011C, the part to look at first is the sensor named here.

Check these first

• The fluid reservoir level sensor A is stuck or failed
• An open or short in the sensor A signal circuit
• Corrosion at the sensor A connector
• Low fluid in the reservoir the sensor A monitors

What to do next

1. Check the fluid level in the reservoir
2. Read the sensor A level with a scan tool
3. Inspect the sensor A connector for corrosion
4. Test the sensor A signal circuit for opens and shorts
5. Replace the fluid reservoir level sensor A if the reading is wrong
6. Clear the code and retest
