- Faulty Vehicle Speed Sensor.
- Damaged wiring or connectors in the VSS circuit.
- Corrosion or poor connections in the VSS circuit.
- ECM software or hardware issues.
- Environmental factors such as water intrusion or debris affecting the VSS.
Symptoms of P2160 2017 GMC Sierra
- Check Engine Light illuminated on the dashboard.
- Inaccurate speedometer readings or erratic speedometer behavior.
- Transmission shifting irregularities or harsh shifting.
- Loss of cruise control functionality.
- Reduced engine power or acceleration.
