Code P159C Nissan Description

The G Sensor has a semiconductor acceleration sensor and detects the longitudinal G and tilt angle of the vehicle based on gravitational acceleration. In addition, the G sensor converts a detected tilt angle into an electric signal and transmits it to Engine Control Module (ECM). The Diagnostic Trouble Code (DTC) will be set when the G sensor signal to the ECM is not within factory specifications.
