Left Rear Wheel Speed Sensor A Range/Performance

Where it lives

For C050D, start at the sensor the description names.

Check these first

• The left rear sensor fouled by debris
• A worn sensing element inside the sensor
• A damaged or missing rear tone ring
• An air gap out of spec at the left rear wheel
• A loose sensor mount

What to do next

1. Inspect the left rear sensor and tone ring
2. Clean the sensor face and the ring
3. Check the air gap against spec
4. Replace the sensor or tone ring if damaged
5. Clear the code and retest on a drive
