What does code C0553 mean?

Q: What does code C0553 mean?

Longitudinal Acceleration Sensor Circuit Low. C0553 means the electronic stability control module has detected a low voltage signal from the longitudinal acceleration sensor, which measures forward and backward g-forces during braking and acceleration. The computer expects a signal within a specific voltage range, and a reading below that threshold triggers this code because the sensor circuit is either shorted to ground, open, or the sensor itself has failed.
