C0711 – Steering Angle Sensor Performance

C0711 – Steering Angle Sensor Performance means the ABS/ESC module is receiving incorrect, inconsistent, or implausible steering-angle information from the Steering Angle Sensor (SAS). Since ESC, traction control, ABS modulation, and advanced safety systems rely on precise steering data, this fault often disables stability control and triggers dashboard warning lights. This guide explains what C0711 means, symptoms, the most common causes, how to diagnose it, and the best repair solutions.

What Does C0711 Mean?

C0711 is a chassis-related fault code stored when the ABS/ESC module detects a performance issue in the steering angle sensor signal. Unlike C0710—which focuses on electrical faults—C0711 refers to incorrect or implausible data. This includes readings that jump suddenly, drift, fail to return to center, or do not match yaw and wheel-speed sensor inputs.

The fault often occurs after alignment work, steering-column repairs, battery issues, or a weak clock spring. When the ESC module sees steering-angle data that doesn’t match vehicle movement, it logs the code and disables stability assistance to prevent unsafe intervention.

Real-World Example / Field Notes

A mid-size SUV arrived with ESC and traction control warnings after a wheel alignment. The steering angle sensor showed a 15° offset even when the wheel was physically centered. The cause was a misaligned SAS that required calibration. After performing a reset with a scan tool, the ESC system returned to normal and C0711 cleared.

Another case involved a luxury sedan where steering-angle readings fluctuated randomly. Live data showed jittering values caused by a failing clock spring inside the steering column. Replacing the clock spring restored a smooth sensor signal and permanently resolved C0711.

Symptoms of C0711 – Steering Angle Sensor Performance

  • ESC or traction control light: Stability control disabled due to invalid steering input.
  • ABS warning light: ESC cannot function without accurate SAS data.
  • Steering-wheel-center offset: Vehicle pulls or ESC intervenes incorrectly.
  • Unstable or unpredictable ESC activation: ESC may activate at the wrong time.
  • Loss of lane-keep or driver-assist features: Many ADAS systems depend on SAS accuracy.
  • Temporary loss of traction during turning: ESC logic may miscalculate yaw and slip.

Common Causes of C0711

Most Common Causes

  • Steering angle sensor misalignment
  • Clock spring (spiral cable) failure
  • SAS performance degradation after alignment or steering repair
  • Low battery voltage affecting sensor output
  • Loose, dirty, or corroded SAS connector

Less Common Causes

  • Damaged CAN wiring around steering column
  • Moisture inside steering column or sensor housing
  • Faulty power steering angle encoder (depending on system)
  • Internal ESC/ABS module misinterpretation of SAS data
  • Incorrect tire sizes causing mismatch in ESC calculations

Diagnosis: Step-by-Step Guide

C0711 requires evaluating steering-angle behavior, checking alignment offsets, and verifying smooth sensor output through a scan tool.

Tools You’ll Need

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

  1. Scan for ABS/ESC codes: Look for companion codes such as C0710 or U0126.
  2. Check live SAS data: Slowly turn the wheel from lock-to-lock and confirm smooth, linear angle changes.
  3. Verify steering-wheel center position: Ensure the SAS value matches physical wheel alignment.
  4. Perform SAS calibration: Required after many alignments or steering repairs.
  5. Inspect the clock spring: Look for intermittent signal loss during wheel rotation.
  6. Check wiring and connectors: Look for looseness, corrosion, or pin damage.
  7. Verify battery and charging voltage: Low voltage can cause SAS signal jitter.
  8. Check for steering column play: Excess movement can confuse sensor logic.
  9. Test SAS signal with oscilloscope (advanced): Identify jitter, noise, or dropouts.
  10. Replace the SAS if necessary: Only after confirming calibration and wiring integrity.

Pro Tip: If C0711 appears right after a wheel alignment, the fix is almost always an SAS calibration—not a faulty part.

Possible Fixes & Repair Costs

  • Steering angle sensor calibration: €50–€120
  • Repair or clean 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 C0711?

You can continue driving, but ESC, traction control, and certain ADAS features may be disabled or unpredictable. This reduces safety on slippery or curved roads. The vehicle should be repaired and recalibrated as soon as possible to restore stability control.

FAQ

Is C0711 the same as C0710?

No. C0710 is an electrical fault; C0711 is a performance or implausibility issue.

Will a wheel alignment cause C0711?

Yes. If the SAS is not recalibrated afterward, the ESC module may see incorrect steering data.

Can a bad clock spring trigger C0711?

Absolutely. A failing clock spring often causes unstable or jittering SAS readings.

Can low battery voltage cause SAS performance issues?

Yes. Many stability control faults begin with weak voltage or charging-system problems.

Does C0711 require replacing the steering angle sensor?

Only after verifying calibration, wiring, and clock-spring condition. Many cases require no parts.
