Car is still @ dealer and they called me to say that the diagnostics are inconclusive.
So I researched it the code and according to the
http://www.fordobdcode.com/p0020-ford web site
P0020 - "A" Camshaft Position Actuator Circuit (Bank 2)
OBD Trouble Code P0020 "A" Camshaft Position Actuator Circuit
What does the code mean? OBD-II Code P0020 definition:
A P0020 code definition:the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car's PCM (powertrain control module). That consists of an oil control valve (OCV), also called a solenoid valve and other components. Basically the check engine light and associated P0020 trouble code means that the voltage in the circuit has fallen below a set limit for a specific amount of time (varies by make/model/engine). Bank 2 is the side of the engine that doesn't contain cylinder #1. Note: This DTC is nearly identical to P0010
Symptoms of OBD code P0020Check Engine Light illuminated (Malfunction Indicator Lamp) Rough running other symptoms may also be present
Causes of the OBD-II code P0020A code P0020 may mean that one or more of the following has happened: Faulty oil control valve (OCV) Open or short in the VVT/VCT circuit Open or short in the OCV / solenoid valve Damaged computer (PCM)
Solutions Some recommended troubleshooting and repair steps are: Carefully inspect the Bank 2 VVT/VCT system circuit wiring and connectors, repair as required with a warm engine, test the operation of the OCV, replace/repair as needed
