What does code P215B mean?

Q: What does code P215B mean?

Vehicle Speed - Output Shaft Speed Correlation. P215B indicates that the powertrain control module (PCM) has detected a mismatch between the vehicle speed reported by the wheel speed sensors and the output shaft speed reported by the transmission output shaft speed sensor. The computer expects these two signals to correlate closely under normal driving conditions, and it sets this code when the calculated difference exceeds a calibrated threshold for a set period of time.
