DTC 1306

Wastegate Valve Control Solenoid Valve (DTC: 1306, 1307)




SYSTEM DESCRIPTION




OPERATION




COMPONENT DESCRIPTION
The solenoid valve responds to the ON/OFF signal from the ECM. When it is ON, a vacuum signal from the suction pipe or compressor outlet is fed into the wastegate valve actuator. The actuator is hard to open at this time. When the control module sends an OFF signal, the coil pulls the plunger upward and cuts the route to the suction pipe.




* Freeze frame data is not stored in the ECM for the wastegate valve control solenoid valve. The MIL will not light up for a wastegate valve solenoid valve malfunction.
