Description and operation

Description

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

Inspection

1.	Switch "OFF" the ignition.

2.	Disconnect the RCV control solenoid valve connector.

3.	Measure resistance between the valve terminals 1 and 2.

Check that the resistance is within the specification.

Specification : 28.3 - 31.1 Ω [20°C(68°F)]

Removal

1.	Switch "OFF" the ignition and disconnect the negative (-) battery terminal.

2.	Remove the RCV control solenoid valve after disconnecting the connector (A), RCV hoses (B).

Installation

•	Do not apply oil when hose is assembled.

•	The hose should be inserted perfectly to nipple.

1.	Install in the reverse order of removal.

Kia Stinger (CK) 2018-2023 Service Manual: A/C Pressure Transducer

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.
