P0020 - B Camshaft Position Actuator Circuit (Bank 2)

Description and meaning of DTC p0020

This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles, including but not limited to Toyota, VW, Ford, Dodge, Honda, Chevrolet, Hyundai, Audi, Acura, etc. A P0020 code refers to the VVT (variable valve timing) or VCT (variable camshafttiming) components and the car's PCM (powertrain control module) or ECM (engine control module). VVT is a technology used in the engine to allow it to get greater power or efficiency at different running points. That consistsof an oil control valve (OCV), also called a solenoid valve and other components. Basically the check engine light and associated P0020 trouble code means thatthe voltage in the circuit has fallen below a set limit for a specific amountof time (varies by make/model/engine). Bank 2 is the side of the engine thatdoesn't contain cylinder #1. Note: This DTC is nearly identical to P0010
