What does code P2090 mean?

Q: What does code P2090 mean?

'B' Camshaft Position Actuator Control Circuit Low (Bank 1). P2090 indicates that the powertrain control module has detected an abnormally low voltage or current draw on the control circuit for the bank 1 'B' camshaft position actuator, which is the solenoid that advances or retards the camshaft for variable valve timing. The computer expects a specific electrical response when it commands the actuator, and a low reading means the circuit is grounded, open, or the actuator itself has failed electrically.
