Q: What does code P1396 mean?

Wheel Speed Sensor 2 G-Sensor Circuit Performance. P1396 on GM vehicles indicates that the powertrain control module (PCM) has detected a performance problem with the wheel speed sensor 2 signal as it correlates to the G-sensor (gravity sensor) circuit. The PCM monitors the wheel speed sensor 2 input and compares it to expected values from the G-sensor to verify that the sensor is accurately reporting wheel speed and that the circuit is not skewed or intermittent.
