Each Coyote cam wears a TiVCT phaser-with sprockets above-at its drive end. The phasers are two-piece, with the timing chain attached to the sprocketed outer hub and the cam bolted to the second piece, which nests inside the hub. The other units shown are the variable force solenoids. They control the phasers by pushing a button on the phasers. The VFS electrical connections pass through the top of the cam cover.
