The steering angle sensor (SAS) is a critical input to the electronic stability control (ESC), ABS, and active safety systems on modern vehicles. When it fails, the ESC and traction control warning lights illuminate and safety systems may be disabled. This guide covers steering angle sensor replacement and calibration costs in the UAE for 2026.
What Does the Steering Angle Sensor Do?
The SAS measures the exact angle and rotation rate of the steering wheel and sends this data to the vehicle safety computers. The ESC system compares the intended steering direction with the actual vehicle movement (from yaw rate and lateral acceleration sensors) to detect and correct oversteer or understeer. If the SAS data is incorrect, the ESC cannot function properly.
Steering Angle Sensor Replacement Cost UAE 2026
OEM or genuine SAS: AED 250 to AED 700 depending on vehicle. Aftermarket SAS: AED 150 to AED 400. Labour for sensor replacement: AED 150 to AED 300. SAS calibration using diagnostic tool: AED 100 to AED 200 (often included in the labour charge at a specialist). Total all-in cost: AED 400 to AED 1,200 depending on vehicle and whether an OEM or aftermarket sensor is used.
Why Does the SAS Need Calibration?
After replacement (or after any wheel alignment, steering component replacement, or battery disconnect on some vehicles), the SAS must be calibrated by driving the vehicle in a straight line and zeroing the sensor with a diagnostic tool. Without calibration, the ESC system uses an incorrect zero reference and the steering angle warning or ESC fault remains active. Some dealers perform a dynamic calibration (driving in a figure-eight pattern at low speed); most specialist workshops use OBD diagnostic software to perform a static calibration.
