2004 Chrysler Pacifica ProblemsTicking Noise From Engine
The engine may develop a ticking noise, often caused by a broken retaining pin on the rocker arm shaft. When the pin breaks, the shaft can spin blocking the oil passage the rocker arms (which causes the ticking noise). The rocker arm shafts, rocker arms, and pedestals (sold as a kit) are commonly replaced in order to correct this condition.
Misalignment of the drive belt pulleys can cause a chirping or squeaking noise from the drive belt.
Carbon buildup on the valves may illuminate the Check Engine Light, indicating "Multiple Cylinder Misfires." The combustion chamber must be cleaned of carbon. There are updated valve spring retainers that will help prevent a recurrence.

I started the engine to verify that code had cleared and it had. 1 minute while still in park, the code returned...never took auto out of park...does this isolate the problem to a sensor??
