P2B44A Camshaft Position Actuator Position Sensor B Range/Performance Bank 2

P2B44 indicates that the powertrain control module has detected an out-of-range or erratic signal from the Bank 2 camshaft position actuator position sensor B, which monitors how far the variable camshaft timing phaser has moved. The computer compares the commanded actuator position with the actual sensor feedback and sets the code when the two do not agree within a calibrated window.
