Condition

Some customers may comment on a malfunction indicator lamp (MIL) on and/or an engine misfire/tick noise.

Technicians may find DTC P0300 set or in history.

Cause

This may be caused by one of the following conditions:

Correction

Note: Inspect the camshaft for damage while the lifters are removed from the engine. If damage is found, replace the camshaft per SI.

If SI diagnosis does not isolate the cause of this concern, technicians should inspect for valve operation.

If the valve(s) are not moving, replace the valve lifter oil manifold and affected bank of AFM lifters. Refer to Valve Lifter Oil Manifold Replacement and Valve Lifter Replacement in SI.

If the lifter has spun the bore, the guides should also be replaced.

Recommendation/Instructions

With the lifter removed, be sure to inspect the bore for any damage. Typically, the lifter bores will look good with no indication of damage.
