P0906

2017-10-10

Description:

  • The fault code P0906 indicates a low voltage condition in 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 the voltage signal from the gear shift lever position sensor falls below the specified threshold, suggesting a potential issue with the sensor or its electrical circuit.

Possible Symptoms:

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

  • Difficulty or failure to shift gears smoothly.

  • Inaccurate gear selection display on the instrument panel.

  • Inconsistent or erratic gear shift lever operation.

  • Possible loss of power or drivability issues.

Possible Causes:

  • Faulty gear shift lever position sensor

  • Wiring or connector problem in the gate select position circuit

  • Poor electrical connection or ground

  • Damaged or corroded sensor terminals

  • Short circuit or open circuit in the circuit

  • Faulty engine control module (ECM)

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.

  • Ensure a secure and clean electrical connection and proper grounding for the gate select position circuit.

  • Repair any damaged or corroded sensor terminals.

  • Check for any short circuits or open circuits in the circuit. Repair or replace components as necessary.

  • If all else fails, consider testing or replacing the engine control module (ECM) if it is determined to be faulty.
