Hyundai Palisade (LX2): Engine Control System / Purge Control Solenoid Valve (PCSV)
Description and operation
Installed on the intake manifold, the Purge Control Solenoid Valve (PCSV) controls
the evaporative purge between the canister and the intake manifold. It is a
solenoid valve and is open when the ECM grounds the valve control line. When
the passage is open (PCSV ON), fuel vapor stored in the canister is transferred
to the intake manifold.

Description and operation
Description
Based on information from various sensors, the ECM can calculate the fuel amount
to be injected.
Description and operation
Description
Continuous Variable Valve Timing (CVVT) system advances or retards the valve
timing of the intake and exhaust valve in accordance with the ECM control signal
which is calculated by the engine speed and load.
