What does code P23EC mean?

Q: What does code P23EC mean?

Camshaft B Position Signal Output Circuit Open Bank 1. P23EC indicates that the powertrain control module (PCM) has detected an open circuit in the output signal path for the bank 1 camshaft B position sensor. The PCM monitors the signal wire for expected voltage changes as the camshaft rotates and sets this code when the circuit remains open, meaning the sensor's signal never reaches the controller.
