2004.5 Spectra Technology
The CVVT assembly can be tested with 14 PSI of air.
The CVVT should be in the retarded position with the
lock pin in place. Plug the OCV passage line holes on
the camshaft, except the hole closest to the CVVT
assembly. Blow air into the unblocked hole to release
the lock pin. Depending upon the air pressure, the
assembly should be able to be turned in the direction
of advance. When the assembly is turned to the
maximum retarded position the pin will relock.
Relocking will occur without air pressure.
CVVT TIMING
Chain Auto-Tensioner
The CVVT assembly is located on the rear of the
exhaust camshaft, which is driven by the timing belt.
A chain attached to the CVVT housing drives the
intake camshaft.
To time the camshafts and chain, place the crankshaft
on #1 piston TDC compression, similar to timing belt
replacement. The camshafts are timed by aligning
each of the 2 brass colored chain links with the dot on
