What it means
VES sensor signal voltage above expected range. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
At a glance
- Usually lights the ABS or stability-control warning light
- The engine or gearbox may go into limp mode
How it works
The variable-effort steering sensor sends a signal voltage to the control module. This high-circuit code sets when that signal rises above the expected range, often because the signal is shorted to battery voltage or its circuit is otherwise biased high.
Common causes
Most likely first.
- Signal wire shorted to battery
- Connector pins corroded - high contact resistance
- Supply wire pinched against B+ source
Symptoms
- ABS warning light on
- ESC/stability control deactivated
- Possible reduced brake assist
- Speedometer may behave erratically
How to diagnose it
- Record freeze-frame data and scan for related steering codes to determine whether the high signal coincided with a supply-voltage fault.
- Inspect the sensor connector and harness for pinched insulation, contact with a battery-positive source, corrosion, or pushed-back terminals.
- Check sensor power, ground, and signal using the wiring diagram and manufacturer's specification.
- With the circuit safely isolated as directed by the service procedure, check whether the signal wire is shorted to battery voltage.
- Gently move the harness while monitoring the signal to identify an intermittent contact with a powered wire.
- If the circuit passes, test the sensor and control-module input before deciding which component has failed.
Common fixes
- Repair pinched or chafed wiring that is contacting a powered source.
- Clean and secure corroded or loose connector terminals.
- Correct a poor sensor ground or supply connection.
- Replace the sensor if it produces an excessive signal with a verified circuit.
- Repair the control module only if its input fails the specified tests.
Can I keep driving?
ABS and stability control assistance may be disabled, and brake assist may be reduced. Avoid fast driving and abrupt manoeuvres; stop if steering or braking behavior changes.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
