P0904

2017-10-10

Description:

  • The fault code P0904 relates to the gate select position circuit. The gate select position refers to the position of the gear shift lever in vehicles with a manual transmission. This code is triggered when there is an issue detected in the gate select position circuit, indicating a potential problem with the gear shift lever position sensor or its control system.

Possible Symptoms:

  • Malfunction Indicator Lamp (MIL) or Check Engine Light illuminated.

  • Difficulty or failure to shift gears.

  • Gear shift lever feels loose or wobbly.

  • Inability to engage specific gears.

  • Incorrect gear selection display on the instrument cluster.

  • Delayed or erratic response when shifting gears.

  • Vehicle may go into limp mode or limited functionality mode.

Possible Causes:

  • Malfunctioning gear shift lever position sensor

  • Wiring or connector problem in the gate select position circuit

  • Mechanical issue with the gear shift lever mechanism

  • Faulty gate select control module

  • Low battery voltage or electrical power supply issues

Related Parts:

  • Gate Position Actuator: The gear gate assists in gear shifting. This actuator controls how the gear is selected. If the actuator fails to select the right gear, there may be slippage or other malfunctions

Possible Solutions:

  • Inspect the gear shift lever position sensor for any signs of damage or malfunction. Replace if necessary.

  • Check the wiring and connectors in the gate select position circuit for any damage, loose connections, or corrosion. Repair or replace as needed.

  • Verify the operation of the gate select control module. Update or replace if it is found to be faulty.

  • Test the gear shift lever mechanism for any mechanical issues. Repair or replace components as necessary.

  • Ensure the battery voltage and electrical power supply to the gate select position system are stable and within the required specifications.
