What does code P1395 mean?

Q: What does code P1395 mean?

Wheel Speed Sensor 2 G-Sensor Circuit. P1395 on GM vehicles indicates that the powertrain control module has detected an abnormal signal from the wheel speed sensor 2 circuit, which on many GM platforms is integrated with or shared by the lateral G-sensor used for stability control. The computer monitors the expected voltage or signal pattern from this sensor and flags the code when the return signal falls outside the calibrated range for a set period. This fault can disable the anti-lock braking system and stability control, so diagnosing it promptly is important for safety.
