If a vehicle equipped with electric power steering (EPS) pulls to the left after alignment, what is a likely cause?

A vehicle equipped with electric power steering (EPS) pulling to the left after an alignment can indicate that the EPS system needs to be re-centered. When the alignment is performed, the steering system must be calibrated to ensure that the steering wheel is centered when the vehicle is going straight. If this calibration is off, the EPS will not provide the correct assist or feedback to the driver, leading to a pulling sensation to one side. This is particularly relevant in EPS systems, as they rely on accurate sensor readings to function correctly. Re-centering the EPS aligns the electronic control module with the actual position of the steering wheel, restoring proper vehicle handling and ensuring that the assist is applied evenly, which can resolve the pulling issue.
