Laymans terms

Your car has a part called a camshaft that helps the engine run smoothly. This code means that the camshaft isn't moving as fast as it should, like when you try to run but your legs feel slow.

Explanation

The engine control module (ECM) has detected that the camshaft timing for Bank 1 is not responding as quickly as expected.

Technical description

The P000B code indicates that the camshaft position actuator for Bank 1, Camshaft B, is not adjusting the camshaft timing as quickly as the ECM expects. This can affect engine performance and efficiency.
