F 150 4WD V8-4.6L VIN 8 (2010)
15. Use the plus button to command to 4 degrees. (One click is equal to 1 degree) When commanding the advance, both banks will normally adjust.
16. Listen carefully to the low frequency knock noise while commanding the VCT_DSD from 0 to 4 degrees. Some higher frequency clatter is normal
at or above the 5 degree advance. What is being pursued is for the level of the low frequency knock noise to be noticeably reduced when advanced
from 4 to 5 degrees.
a. If noise level is noticeably reduced as the VCT desired angle is commanded from 3 to 4 degrees, the noise source is the RH VCT phaser
assembly. Proceed to Step 17.
b. If the low frequency knock noise is not noticeably reduced at 4 degrees, refer to WSM, Section 303-00 for engine noise diagnostics.
17. Due to normal engine dynamics, the VCT phaser knock noise is produced by the RH VCT phaser assembly. Replace only the RH VCT phaser
assembly. Refer to WSM, Section 303-01.
