Oil Temperature Sensor
The VCT system uses a replaceable oil temperature sensor, located on the oil pan.
•
Engine oil temperature has a direct effect on VCT operation.
– Cold engine oil has high viscosity and slower flow characteristics.
– The VCT system is disabled at oil temperatures below -7°C (18°F).
– The PCM uses time-since-start, engine oil temperature and engine rpm to calculate VCT solenoid operation.
– Time-since-start ranges from 60 seconds when cold to 10 seconds when hot.
•
Recommended engine oil change intervals must be followed to ensure the integrity of VCT system.
– Oil Capacity - 6.6L (7.0 quarts).
– Oil Specification - Motorcraft SAE 5W20 Premium Synthetic Blend Motor Oil.
