What does code P23EB mean?

Q: What does code P23EB mean?

Camshaft A Position Signal Output Circuit High Bank 2. P23EB indicates that the powertrain control module has detected an abnormally high voltage on the output circuit for the bank 2 camshaft A position signal. The circuit is expected to switch between low and high states as the camshaft rotates, but the module sees the signal stuck at or above its normal high threshold, which prevents reliable valve timing feedback.
