Description:

  • The fault code indicates a high voltage condition in the gear shift reverse actuator circuit. The gear shift reverse actuator is responsible for controlling the reverse shifting of gears in the transmission. A high voltage condition suggests that the circuit is receiving a voltage level higher than the expected range for proper operation.

Possible Symptoms:

  • Difficulty shifting into reverse gear

  • Inability to engage the reverse gear

  • Harsh or delayed shifts in the reverse direction

  • Illumination of the Check Engine Light

  • Impaired drivability and reduced vehicle performance

Possible Causes:

  • Faulty or malfunctioning gear shift reverse actuator

  • Shorted wiring in the gear shift reverse actuator circuit

  • Poor electrical connections or loose connectors in the circuit

  • Faulty transmission control module (TCM)

  • High voltage supply to the circuit

Related Parts:

  • Gear Shift Position Sensor: Gear Shift Position Sensor communicates the position of the gear to the car computer. This car's sensor has a problem which may cause difficulty in shifting gears

Possible Solutions:

  • Inspect and test the gear shift reverse actuator for proper operation, and replace if necessary

  • Check the wiring harness and connectors in the gear shift reverse actuator circuit for any signs of damage, and repair or replace as needed

  • Ensure proper electrical connections are made and secure any loose connectors in the circuit

  • Test the transmission control module (TCM) for any faults and replace if required

  • Verify the voltage supply to the circuit and ensure it is within the specified range
