PURGE CONTROL VALVE
YAA1F440
The fuel vaporization control system is installed to inhibit the fuel vaporized gas from discharging into the
atmosphere. The fuel vaporized gas that is accumulated in the canister abstracts through the purge control valve
purification during the engine combustion (except the decreasing mode) and coolant temperature of over 80 ° C.
For this reason, the Engine Control Module (ECM) transacts the engine speed, air inflow quantity, coolant
temperature, and intake temperature.
The purge control valve is activated by the ECM frequency according with the engine rotating speed to adjust the
purification rate. The purification rate is determined by the continuous valve opening interval.
The purge control valve is activated by the ECM for the following conditions:
•
Coolant temperature of over 80 ° C
•
Engine speed of over 1,000 rpm
•
2 minutes after starting
•
When the fuel cut-off mode is not activated

Test
1. Maintain the normal temperature and idling state
by operating the engine.
2. Connect the ECM terminal No. 11 and No. 34 and
check for normal operation through the output waves
using oscilloscope.
Notice: Test during purge control valve operation
after the minimum of 1 minute after the engine
turned on.
3. Connect the ECM terminal No. 34 and No.10 and
check for current consumption during the ignition
switch ON.
4. Remove the line to canister and measure the
pressure with the vacuum pressure gauge.

2. Stop the engine for approximately 30 minutes and
then check the fuel pressure changes.
Pressure change
Fuel pressure
drops slowly
Fuel pressure
drops rapidly
•
Fuel leakage at the injector
•
Faulty fuel pressure

and O-ring
•
Faulty check valve in
the fuel pump
3. If there is no change in fuel pressure and maintain
the following pressure over 30minutes, it is normal.
5. Replace the pressure regulator diaphragm if out of
the specification.
