P0035 Turbocharger/Supercharger Bypass Valve Control Circuit High - General Information

Component Location





General Description

If suddenly closing the throttle body during driving, the boost pressure within the pipes increase. This increased pressure does not flow into the intake but transfers in the opposite direction and creates a Tipout Surge1), caused by sudden increase in pressure at the impeller within the compressor. This may result in making collision sound. This device helps reduce the collision sound by discharging the highly increased pressure before the compressor rather than after the compressor. Usually positive pressure is connected to the actuator. The RCV is closed at this time. When decelerating after acceleration, the solenoid valve will operate. This act will create a vacuum state connecting the negative pressure to the actuator, which lets it overcome the spring force and pull the diaphragm. At this state, the air entering the combustor does not affect the compressor wheel and exerts action within the air cleaner.

DTC Description

ECM sets DTC P0035 if the ECM detects that the bypass valve control circuit is short to battery.
