Camshaft Slow Response

Diagnostic & Technical Explanation
Code P000A (A Camshaft Position Slow Response Bank 1) sets when a variable valve timing actuator takes longer than the ECM expects to reach its commanded position after a phasing request. The leading causes are degraded engine oil (low pressure or sludge blocking the oil control valve screen), a sticking oil control valve, or wear inside the phaser itself that increases mechanical slack.

These 4 diagnostic trouble codes share one detection mechanism and one repair path, which is why MechanicDB groups them into a single authored fault family rather than repeating the same explanation 4 times.
