On the sensor side, measure resistance between torque sensor 3P connector terminals No. 1 and No. 2, and between terminals No. 2 and No. 3. Is the resistance between 12−14 Ω (at 20 °C (68 °F))?
YES | - | The system is OK at this time. Check for loose terminals and poor connections at EPS control unit and torque sensor. If necessary, substitute a known-good EPS control unit and recheck.■
NO | - | Replace the torque sensor. ■
