illuminated and may have any combination of trouble codes P0101 P0106 P0171
P0300 P16D0 P16D1 P2646 P2647. During diagnosis the technician may nd engine

Cause

The intake rocker arm oil control valve may have an internal electrical or mechanical
concern.

Correction:
If diagnostic procedures in service information do not resolve the vehicle's concern, remove and inspect the
intake rocker arm oil control valve for missing components.
See illustrations below for items #1 being missing.
If any of the components are missing, replace the intake rocker arm oil control valve and camshaft cover.
The camshaft cover must be replaced because the components become lodged in the camshaft cover oil
passages and can not be removed.
If the intake rocker arm oil control valve is not missing any components, only replace the intake rocker arm oil
control valve.
NOTE: If a previous rocker arm control solenoid came apart and pieces are stuck in the cam cover passages, this
can cause any of the concerns to happen even when a new rocker arm control solenoid is installed.
Evaluate the vehicle thoroughly after repairs to verify the concern(s) are corrected.
This is a good valve with components still in place.

This is a bad valve with components missing.
