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 :
lCoolant temperature of over 80°C
lEngine speed of over 1000rpm
l2 Minutes after starting
lWhen the fuel cut-off mode is not activated

M162 ENGINE CONTROLS 1F1-71
If the measured value is not within the specified value, the
possible cause may be in cable or HFM sensor in itself.
Perform the 5V power supply inspection procedures.
HFM Sensor 5V Power Supply Inspection
1. Measure the voltage between the HFM sensor No.108(+) and
No.105(-) after removing the HFM sensor connector.
HFM Sensor Input Voltage Inspection
1. Measure the HFM sensor signal voltage between the ECU
terminal No.103 and No.104.
Specified Value (coolant temperature is over 70°C)
If the measured value is not within the specified value, the
possible cause may be in cable or ECU coupling.
Iginition"ON” 0.9 - 1.1 V
Engine at Idle 1.3 - 1.7 V
Specified Value 4.7 - 5.2 V
2. Measure the voltage between the HFM sensor wining
connector terminal No.3 pin(-) and No.4 after removing the
HFM sensor connector.
Specified Value
If the measured value is not within the specified value, the
possible cause may be in cable or over voltage protection
relay.
Perfrom the 12V power supple inspection procedures.
Specified Value 4.7 - 5.2 V
HFM Sensor 12V Power Supply Inspection
1. Measure the voltage between the HFM sensor wiring
connector 1G No.2 pin(+) and No.104 after removing the
HFM sensor connector.
If the measured value is not within the specified value, the
possible cause may be in cable or over voltage protection
relay.
Specified Value 11 - 14 V
