Description and operation
Installed on the intercooler inlet pipe, the RCV (Recirculation Valve) Control
Solenoid Valve operates the RCV actuator which controls the by-pass passage of the
turbocharger compressor. When the throttle is closed with the engine running at
cruise rpm (tip-out), the turbocharger boost pressure increases rapidly. The pressure
wave strikes a compressor blades causing a knocking noise. To prevent this, the
ECM opens the recirculation valve which allows excessive boost pressure to vent
back to the air cleaner side of the turbocharger compressor.

Repair procedures
| 1. |
Switch "OFF" the ignition.
|
| 2. |
Disconnect the RCV control solenoid valve connector.
|
| 3. |
Measure resistance between the valve terminals 1 and 2.
|
| 4. |
Check that the resistance is within the specification.

Description and operation
Description
A/C pressure transducer measures the pressure in high pressure line and converts
it into voltage. Based on the converted voltage, engine ECU controls cooling fan
by operating it at high or low speed. Engine ECU stops the operation of compressor
when the temperature of refrigerant line is too high or low irregularly to optimize
air conditioning system.
