P000B Code- 'B' Camshaft Position Slow Response Bank 1

What Does Code P000B Mean

A P000B code is stored when the ECM, which monitors and checks the actual position of the camshaft versus a target position, sees that the change in position is smaller than a preset threshold, meaning that the response is slow. Whenever an issue is noted, an anti bounce counter keeps track, and if the counter exceeds a predetermined limit specified by the automaker, a P000B code can be stored.

“B” signals that the issue is with Bank 2, which is typically not the Cylinder 1.
