PURGE SWITCHOVER VALVE
1 Purge Switchover Valve
2 Line to Engine
3 Line to Canister
4 Canister
Functions
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 switchover valve purification during the
engine combustion (except the decreasing mode) and coolant
temperature of over 80
°
C. For this reason, the ECU transacts
the engine speed, air inflow quantity, coolant temperature, and
intake temperature.
The purge switchover valve is activated by the ECU 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 switchover valve is activated by the ECU for the
following conditions :
z
Coolant temperature of over 80
°
C
z
Engine speed of over 1000rpm
z
2 Minutes after starting
z
When the fuel cut-off mode is not activated

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