DTC P0010: Camshaft Position "A" Actuator Circuit (Bank 1); DTC P0020: Camshaft Position "A" Actuator Circuit (Bank 2) [09/2014 - ]: Description
The electric VVT changes the valve timing using a motor. In comparison to a conventional hydraulic VVT, the valve timing range is greater and the VVT operates even when the engine speed is low or the engine is cold. As a result, it is possible to increase engine output and mileage.
The camshaft timing control motor is equipped with a self diagnostic function, which is used to output diagnosis signals (VTM) to the ECM.
| Part and Terminal Name | Function |
|---|---|
| Camshaft timing control motor | Through its electric motor, operates camshaft timing gear assembly. Interior driver (EDU) detects and performs malfunction diagnosis of motor control, motor speed and rotation direction. |
| Camshaft timing gear assembly | Changes valve timing by rotating timing chain sprocket. |
| ECM | Outputs target speed and motor rotation direction in response to driving conditions. |
| +B | Power supply (when engine switch on (IG), 12 V or higher) |
| PGND | Power supply ground |
| VTP | Inputs motor activation signal from ECM. |
| VTS | Outputs actual motor speed. |
| VTD | Outputs actual rotation direction. |
| VTM | Outputs malfunction diagnosis results as a duty ratio.
