The P159A fault code refers to an issue with the G Sensor Circuit in your vehicle. The G Sensor is equipped with a semiconductor acceleration sensor that detects the longitudinal G force and tilt angle of the vehicle using gravitational acceleration.

It then converts the detected tilt angle into an electric signal and sends it to the Engine Control Module (ECM). However, when the G Sensor Circuit malfunctions, it can trigger the P159A fault code.

This code indicates that there is a problem with the G Sensor Circuit, and it needs to be addressed to ensure proper functioning of your vehicle.
