Hyundai i-30: Engine Control System / RCV Control Solenoid Valve
Description and operation
RCV (Recirculation Valve) Control Solenoid Valve is installed on the cooling
pan motor top and operates the RCV actuator which controls the by-pass passage
of the turbo-charger compressor.
When the throttle valve is closed during engine running [Tip-out], crash noise
of the impeller will occur because of rapid increasing of the boost pressure.
So, in this case, in order to prevent this phenomenon, ECM maintains the appropriate
boost pressure by opening the by-pass passage.

Desrcription
Installed on the turbocharger, the Electric Waste Gate Actuator operates the
valve in the Waste Gate Turbocharger (WGT) and regulates the amount of compressed
air by using the ECM’s signals...
Description and operation
Description
The Electric EGR Control Valve is installed in between the EGR cooler and the
exhaust line and is a solenoid valve...
Other information:
You can check the tyre pressure in
the Assist mode on the cluster.
Refer to the "LCD Display
Modes" in chapter 3.
Tyre pressure is displayed after a
few minutes of driving after initial
engine start up.
If tyre pressure is not displayed when
the vehicle is stopped, "Drive to display"
message will appear...
CAUTION
Detach the speed restriction
label (1) from the sealant bottle
(2), and place it in a highly visible
place inside the vehicle
such as on the steering wheel
