What it means

The steering angle sensor measures the direction and amount of steering wheel rotation and sends the reading over the network to electronic stability control and other systems. This code means the message arrives but its content is invalid. The most common cause is a lost sensor calibration after a wheel alignment or steering repair.

Symptoms4

Stability control or traction control (TCS) light on.
Stability control disabled, sometimes ABS or cruise control as well.
On some vehicles, a steering system warning or a change in electric power steering effort.
Problem appears after an alignment, a steering repair or a battery replacement.

Possible causes5

Sensor calibration lost or not performed after an alignment or steering repair.
Internal steering angle sensor failure.
Damaged sensor wiring or connector; on some vehicles it is built into the clock spring behind the steering wheel.
Low battery voltage.
Incorrect programming or coding of the stability module or the sensor module.

How to diagnose5

Read codes from the stability or ABS module and the steering module.
Watch the steering angle reading on a scan tool: it should be close to zero with the wheels straight and change smoothly as the wheel turns.
Make sure the steering wheel is centered after an alignment, since an off-center wheel gives an implausible reading.
Perform the calibration and recheck the codes; if the code returns, inspect the wiring and connector.
Measure battery voltage.

How to fix5

Center the steering wheel with a wheel alignment if it is off.
Calibrate the steering angle sensor with a scan tool following the manufacturer procedure.
Repair the damaged wiring or connector.
Replace the sensor and calibrate it if proven faulty.
Clear the codes, road test and confirm the lights stay off and the code does not return.

In Saudi riyals; the highlighted part is the expected range for this fault.

The cost is low when a calibration or alignment fixes it, and rises if the sensor must be replaced and calibrated, especially when it is built into the clock spring.

Prices are rough estimates for common cars at independent workshops and vary with the car and the source of the part.

Frequently asked questions

Is a calibration enough to fix it?

Often yes, especially if the code appeared after an alignment or steering repair. The sensor is replaced only if the code returns after a correct calibration.

Can I replace the sensor myself?

It is not recommended. On some vehicles it sits behind the steering wheel near the airbag or is built into the clock spring, so a qualified technician should follow the safety procedure and then calibrate it.

This guide is for information only and does not replace an inspection by a qualified technician. If the fault involves brakes, steering, engine temperature, electrics or refrigerant, do not attempt the repair yourself.
