Kia Niro - First generation - (DE) (2017-2022) - Service and Repair Manual / Engine Control / Fuel System / Engine Control System / Purge Control Solenoid Valve (PCSV)
Specification
Purge Control Solenoid Valve (PCSV) Description and operation
Description
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.

Purge Control Solenoid Valve (PCSV) Repair procedures
Inspection
- Switch "OFF" the ignition.
- Disconnect the PCSV connector.
- Measure resistance between the PCSV terminals 1 and 2.
- Check that the resistance is within the specification.
Specification: 14.3 - 14.7 Ω (20ºC(68ºF))
Removal
- Switch "OFF" the ignition and disconnect the negative (-) battery terminal.
- Remove the air cleaner assembly.
(Refer to Engine Mechanical System - "Air Cleaner")
- Disconnect the purge control solenoid valve connector (A).
- Disconnect the vapor hoses (B) from the purge control solenoid valve.
- Remove the purge control solenoid valve.
Installation
Warning
- Note that internal damage may occur when the component is dropped. If the component has been dropped, inspect before installing.
- Use care to keep foreign material out of the valve.
- Install in the reverse order of removal.
