DTC P000B Lincoln
B Camshaft Position Slow Response (Bank 1)
B Camshaft Position Slow Response (Bank 1)
Description
The PCM monitors and evaluates the response of the actual position on a target position change.< p> 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 DTC sets when the counter exceeds an adjustable limit.
Cause and Solution
Variable camshaft timing (VCT) unit to camshaft alignmentErratic camshaft position due to low oil pressureOil flow restriction in the oil passages or the VCT valve bodyCamshaft advance mechanism binding (VCT unit)Damaged VCT phaserRadio frequency interference
Diagnosis:
This DTC may be accompanied by other DTCs. Diagnose all camshaft position (CMP) sensor DTCs first. If no CMP sensor related DTCs are present, continue to follow diagnosis for this DTC. This DTC is a functional check of the VCT unit. Diagnose any base engine concerns related to the engine oil pressure or engine timing.
