Throttle Position Sensor/Switch A Circuit Range/Performance Problem
The throttle pedal sensor is sending signals that don't match what the engine expects based on your driving inputs, suggesting the sensor is wearing out or miscalibrated. This causes the engine to misinterpret your acceleration commands. Your vehicle may hesitate, surge, or feel unresponsive to throttle input.
