P1308 Hyundai Code - Acceleration Sensor Circuit Low Input
Quick Answer
The Chassis acceleration(Rough Road) sensor consists of a piezoelectric vibration pick up which detects vertical acceleration of the vehicle.The sensor signal is used by the Engine Control Module (ECM) to determine the degree of vertical movement of the car, for example, on a bumpy road.Since this may also cause uneven engine running, the ECM uses the signal to distinguish the phenomenon from actual misfiring. Common causes include Faulty Acceleration Sensor, Acceleration Sensor harness is open or shorted, Acceleration Sensor circuit poor electrical conection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
