P0020: "B" Camshaft Position Actuator Circuit (Bank 2)OVERVIEW
What Does The P0020 Code 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) 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 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
What Are The Symptoms Of The P0020 Code?
Symptoms may include:
- Check Engine Light illuminated (Malfunction Indicator Lamp)
- Rough running
- other symptoms may also be present
What Are The Potential Causes Of The P0020 Code?
A 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)
How Can You Fix The P0020 Code?
Some recommended troubleshooting and repair steps are:
- Carefully inspect the Bank 2VVT/VCT system circuit wiring and connectors, repair as required
- With a warm engine, test the operation of the OCV, replace/repair as needed
