DTC Troubleshooting: 91-03

  1. On the sensor side, check for resistance between torque sensor coil 3P connector terminals No. 1 and No. 3.
Is the resistance between 24−30 Ω at 20 °C (68 °F)?
YES -
Check for loose terminals in the EPS control unit connectors, and repair if necessary. If all connections are OK, replace the EPS control unit. ■
NO -
Faulty torque sensor (short or open in the internal circuit), replace the steering gearbox. ■
