On my way home from work today, the check engine light came on, and I got the codes P0300 and P0020.
I looked up the code P0020, and this is what I found:

What does that mean?
A P0020 code refers to 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

CausesA code P0020 may mean that one or more of the following has happened:
