C0053 DTC: Left Rear Wheel Speed Sensor Circuit Low

What Does C0053 Mean?

Diagnostic Trouble Code (DTC) C0053 indicates that the ABS control module has detected a voltage or signal level below the expected operating range in the left rear wheel speed sensor circuit. This fault is commonly caused by a short to ground, excessive circuit resistance, damaged wiring, poor electrical connections, or a faulty wheel speed sensor.

Symptoms

• ABS warning light illuminated
• Traction Control (TCS) warning light ON
• Electronic Stability Control (ESC) warning
• ABS disabled during hard braking
• Traction Control unavailable
• Cruise control may be disabled on some vehicles
• Additional ABS-related DTCs stored

Common Causes

• Faulty left rear wheel speed sensor
• Sensor circuit shorted to ground
• Damaged or pinched wiring harness
• Loose, corroded, or water-damaged connector
• Damaged tone ring (reluctor ring)
• Incorrect sensor air gap caused by wheel bearing wear
• Faulty ABS control module (rare)

Inspect Sensor, Wiring, Connector & Tone Ring

How to Diagnose C0053

• Read ABS DTCs using a professional scan tool.
• Monitor live wheel speed data while driving.
• Compare the left rear wheel speed with the other three wheels.
• Inspect the wiring harness for damage or contact with ground.
• Check the connector for corrosion, moisture, or loose terminals.
• Inspect the tone ring for cracks, rust, or missing teeth.
• Measure sensor resistance and circuit voltage according to manufacturer specifications.

Typical Values

• All wheel speed sensors should report nearly identical wheel speeds during normal driving.
• A low or missing signal usually indicates a sensor or circuit fault.
• Exact specifications vary by vehicle manufacturer.

Estimated Repair Cost

• Wheel speed sensor replacement: $70–250
• Wiring repair: $50–200
• Connector replacement: $30–120
• Tone ring replacement: $80–300
• Wheel bearing replacement: $150–500
• ABS module replacement: $400–1,200

Frequently Asked Questions

Can I drive with C0053?

Yes. Normal braking remains available, but the ABS, Traction Control, and Stability Control systems may be disabled until the fault is repaired.

What is the most common cause of C0053?

The most common causes are a faulty left rear wheel speed sensor, wiring shorted to ground, damaged connectors, an incorrect sensor air gap, or a damaged tone ring.

Will clearing the DTC permanently fix C0053?

No. Clearing the code only removes it temporarily. If the low-voltage condition remains, the ABS module will detect the fault again during the next self-test.
