Left Rear Wheel Speed Sensor A Correlation

Where it lives

For C0511, start at the sensor the description names.

Check these first

• The left rear sensor reading out of step with the others
• A damaged rear tone ring
• A wrong sensor with a different tone count
• A tire size mismatch across the rear axle
• A dirty or loose left rear sensor

What to do next

1. Compare all four wheel speeds on a scan tool
2. Inspect the left rear tone ring
3. Check tire sizes and pressures across the axle
4. Replace the sensor or ring if the signals differ
5. Clear the code and retest
