Code P0905 Description
The diagnostic trouble code (DTC) P0905 indicates a problem with the gate select position circuit's range or performance. This code typically affects vehicles with automatic transmissions, particularly those with a manual shift mode or semi-automatic transmission. The gate select position circuit is responsible for accurately detecting and transmitting the gear selection made by the driver to the vehicle's transmission control module (TCM). When this circuit malfunctions, it can lead to incorrect gear selection, erratic shifting behavior, and even a complete inability to shift gears.
Common Causes of P0905
- Malfunctioning gate select position sensor
- Damaged wiring or connectors in the circuit
- Faulty transmission control module (TCM)
- Issues with the transmission linkage or shift mechanism
- Electrical issues such as blown fuses or relay failures
Symptoms of P0905
- Harsh shifting or rough gear changes
- Delayed engagement when shifting gears
- Inaccurate gear selection display on the instrument cluster
- Transmission slipping or jerking during acceleration
- Inability to shift gears or stuck in a single gear
How to Fix P0905
- Diagnose the root cause of the issue by conducting a thorough inspection of the gate select position circuit, sensors, wiring, and TCM.
- Test the gate select position sensor for proper functionality using a multimeter or scan tool.
- Repair or replace any damaged wiring or connectors in the circuit as needed.
- Replace the faulty gate select position sensor or TCM if they are found to be the source of the problem.
- Clear the DTC from the vehicle's memory using an OBD-II scanner and perform a test drive to ensure the issue has been resolved.
Cost to Fix P0905
The typical repair costs for addressing a P0905 code can vary depending on the specific cause of the issue and the vehicle's make and model. In general, replacing a faulty gate select position sensor or repairing damaged wiring can cost anywhere from $150 to $400. If the issue is related to a malfunctioning TCM, the repair costs may be higher, ranging from $500 to $1000 or more. Labor rates at auto repair shops can range from $80 to $150 per hour, with additional charges for diagnostic time and any necessary parts.
