What it means
The control module monitors the variable effort steering sensor circuit. It sets this code when the circuit signal is faulty or outside the expected range.
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 provides a signal the control module uses to assess steering-system operation. This circuit code sets when the sensor signal is faulty or outside the expected range, without specifying whether it is too low or too high.
Common causes
Most likely first.
- Failed steering sensor
- Damaged wiring or poor connection
- Corroded connector
- Control module fault
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 and ABS codes to identify when the sensor fault occurred and whether other circuits are affected.
- Check battery and charging voltage against the manufacturer's specification, since supply problems can distort sensor readings.
- Inspect the variable-effort steering sensor, its connector, and nearby harness for damage, corrosion, loose pins, or poor seating.
- Check the sensor's power, ground, and signal circuit using the vehicle wiring diagram and manufacturer's diagnostic procedure.
- Compare live sensor data with steering input and check for dropouts or implausible changes while gently moving the harness.
- If wiring and connections pass, test the sensor and verify module inputs before condemning the control module.
Common fixes
- Clean and secure the sensor connector or repair a poor connection.
- Repair damaged sensor wiring or restore a sound ground.
- Replace a failed variable-effort steering sensor.
- Repair or reprogram the control module only if circuit and sensor tests confirm the fault is there.
Can I keep driving?
ABS or stability control assistance may be unavailable, and brake assist may be reduced. Drive cautiously only if steering and braking feel normal, and have the fault checked promptly.
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.
