P1308 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 Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.
