C0710 – Steering Angle Sensor Circuit

C0710 – Steering Angle Sensor Circuit means the ABS/ESC module has detected an electrical fault, inconsistent signal, or loss of communication from the steering angle sensor (SAS). This sensor tells the vehicle how quickly and how far you are turning the steering wheel. When it fails, stability control, traction control, and ABS may not respond correctly, leading to warning lights and reduced handling stability. This guide explains what C0710 means, symptoms, causes, diagnosis steps, and proven repair solutions.

What Does C0710 Mean?

C0710 is a chassis-related OBD-II fault code set when the steering angle sensor circuit behaves abnormally. The SAS monitors steering-wheel position and rotation rate, then shares the data with the ABS/ESC module to manage traction control, yaw stability, and cornering safety. If the sensor output is out of range, inconsistent, or unreadable, the module logs C0710.

The fault may be caused by wiring issues, a failing SAS, low voltage conditions, or a misaligned sensor after steering or suspension repairs. Many vehicles require SAS calibration after work on the steering column or wheel alignment.

Quick Reference

  • OBD-II Family: C-Code (Chassis)
  • Scope: Generic
  • System: Steering Angle / ESC / ABS
  • Difficulty Level: Easy–Moderate
  • Estimated Repair Cost: €70–€350+

Real-World Example / Field Notes

A compact sedan arrived with ESC and traction lights illuminated. Live steering-angle data showed sudden jumps and dropouts. The SAS connector under the steering column had loosened over time, causing intermittent signal loss. Securing the connector and recalibrating the SAS cleared C0710 immediately.

In another case, an SUV triggered C0710 right after a wheel alignment. The steering angle sensor had not been recalibrated after adjusting the toe. After performing a quick SAS calibration using a scan tool, the fault cleared and stability control returned to normal operation.

Symptoms of C0710 – Steering Angle Sensor Circuit

  • ESC or traction control light: Stability systems disabled.
  • ABS warning light: ESC relies on steering-angle data.
  • Reduced stability during cornering: Vehicle may feel less predictable.
  • Steering-wheel-center issues: ESC may activate unnecessarily.
  • Inoperative lane-keep or advanced safety features: Some systems require SAS data.
  • Temporary loss of traction control: Especially during quick turns.

Common Causes of C0710

Most Common Causes

  • Failed steering angle sensor
  • Loose, corroded, or damaged SAS connector
  • Clock spring (spiral cable) malfunction
  • Steering wheel or column work without SAS recalibration
  • Low battery voltage dropping sensor signal

Less Common Causes

  • Damaged CAN wiring affecting SAS communication
  • Moisture intrusion inside steering column
  • Faulty ABS/ESC control module interpreting SAS data incorrectly
  • Incorrect tire sizes affecting ESC logic
  • Mechanical steering play confusing sensor alignment

Diagnosis: Step-by-Step Guide

C0710 requires verifying accurate SAS data, checking wiring integrity, and recalibrating the sensor when applicable.

Tools You’ll Need

Advanced scan tool with SAS calibration function, multimeter, wiring diagrams, trim-removal tools, and optional oscilloscope.

  1. Scan for additional ABS/ESC codes: Helps identify related communication issues.
  2. Check live SAS data: Turn the wheel slowly and verify smooth angle changes.
  3. Inspect SAS wiring: Look for loose connectors, corrosion, or damaged insulation.
  4. Check the clock spring: Look for intermittent connections when turning the wheel.
  5. Verify battery and charging voltage: Low voltage can cause SAS dropout.
  6. Perform SAS calibration: Many vehicles require recalibration after alignment.
  7. Check steering column for play: Excessive movement can affect sensor readings.
  8. Inspect CAN wiring near steering column: Look for pinched or rubbed wires.
  9. Backprobe SAS signal wires: Ensure clean and stable voltage output.
  10. Replace SAS if confirmed faulty: Only after wiring and calibration checks.

Pro Tip: If C0710 appears after a wheel alignment or steering-wheel removal, the fix is often a simple SAS calibration—no parts required.

Possible Fixes & Repair Costs

  • Steering angle sensor calibration: €50–€120
  • Repair or secure SAS wiring/connector: €40–€100
  • Replace clock spring: €90–€250
  • Replace steering angle sensor: €120–€350+
  • Repair CAN wiring: €60–€180
  • ABS/ESC module repair or replacement: €350–€700+

Can I Still Drive With C0710?

You can still drive, but ESC and traction control may be disabled or behave inconsistently. In slippery weather, emergency maneuvers, or high-speed driving, this can significantly reduce safety. The vehicle should be repaired and recalibrated as soon as possible.

FAQ

Does C0710 always mean the steering angle sensor is bad?

No. Many cases are caused by loose wiring, bad clock springs, or lack of SAS calibration.

Will C0710 disable traction control?

Yes. Without correct steering-angle data, ESC and traction systems cannot function properly.

Do I need a scan tool to fix C0710?

Yes. Most vehicles require scan-tool calibration to reset or realign the steering angle sensor.

Can low voltage cause C0710?

Absolutely. Weak batteries often cause temporary SAS signal dropouts.

Is it safe to drive with C0710?

Short distances may be fine, but the reduced stability makes extended driving risky, especially in poor weather.
