  • Disconnect the battery to prevent electrical shock during repairs.
2. Throttle Position Sensor Inspection
  • Locate the throttle position sensor on the engine.
  • Disconnect the electrical connector from the TPS.
  • Use a multimeter to test the resistance across the sensor terminals; compare readings to manufacturer specifications.
  • If the TPS is faulty, proceed to replace it.
3. Battery Health Assessment
  • Reconnect the battery and use a battery tester to assess the state of charge and health.
  • If the battery is weak or failing, replace it with a compatible unit.
4. Electric Motor Inspection
  • Inspect the electric motor for any signs of physical damage or wear.
  • Check the motor connections for secure fit and corrosion.
  • If issues are detected, consult repair guidelines for motor replacement or repair.
5. Contactors and Wiring Check
  • Visually inspect the contactors and wiring for wear, damage, or corrosion.
  • Clean any corroded connections and ensure all wiring is securely fastened.
  • Replace any damaged wiring or contactors as necessary.
6. Regenerative Braking System Verification
