P0908 — Gate Select Position Circuit Intermittent

System: Powertrain  |  Type: Generic (OBD-II Standard)  |  Make: Generic

About P0908

P0908 is a generic (obd-ii standard) powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P0908 is stored, the module has detected an electrical-circuit fault in the wiring, connector, or driver associated with the named component.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P0908 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The P0908 fault code is set when the transmission control module (TCM) detects intermittent signals in the gate select position circuit. This circuit monitors the lateral (left/right) position of the gear selector in vehicles with manual or semi-automatic transmissions. An intermittent fault in this circuit indicates a sporadic disruption or inconsistency in the signals being transmitted to the TCM regarding the gear selector's position. Such intermittent issues can lead to erratic gear selection behaviour, transmission control problems, and can affect the drivability and safety of the vehicle...
