Q: What does code P23ED mean?

Camshaft B Position Signal Output Circuit Low Bank 1. P23ED indicates that the powertrain control module (PCM) has detected a low voltage condition on the output circuit for the bank 1 camshaft B position sensor signal. This means the circuit is shorted to ground or the sensor's output is not producing the expected voltage swing, so the PCM cannot reliably determine the camshaft's position for variable valve timing and fuel synchronization.
