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

Quick Answer

The Powertrain Control Module (PCM) monitors and evaluates the response of the actual position on a target position change. Common causes include Low or Dirty Engine Oil, Incorrect camshaft timing, Faulty Variable Camshaft Timing (VCT) Solenoid Valve. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P000B Mercury Description

The Powertrain Control Module (PCM) monitors and evaluates the response of the actual position on a target position change. The setpoint and camshaft position are saved at the beginning of a setpoint change. If this change over time is large enough (gradient), the camshaft phasing change is evaluated. If the change after the diagnostic time is smaller than a threshold, a slow response is detected, and if the value is greater, then there is no concern. By detecting a concern, an antibounce counter is incremented otherwise the counter is decremented. This Diagnostic Trouble Code (DTC) sets when the counter exceeds an adjustable limit.
