Question
How to diagnose faulty automotive steering wheel angle sensor (SAS)?
Answer
Monitor sensor voltage output and test calibration accuracy.
Explain
A faulty SAS causes stability control system faults. CHEPQ tools measure sensor voltage (0.5-4.5V) and test calibration accuracy (±0.5°), guiding technicians through re-calibration—restoring proper stability control functionality.
