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. Thefuel vaporized gas that is accumulated in the canister abstractsthrough 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, andintake 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 :
Coolant temperature of over 80 °C
Engine speed of over 1000rpm
2 Minutes after starting
When 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

M162 ENGINE CONTROLS 1F1-73
Oxygen Sensor Signal Voltage Inspection
1. Measure the oxygen sensor signal voltage between the ECUterminal No.11 and No.9. Maintain the engine speed ia at idle while the coolant temperature is over 80 °C.
If the measured value is not within the specified value, thepossible cause may be in cable, oxygen sensor or ECU.
Oxygen Sensor Heating Voltage Inspection
1. Measure the oxygen sensor heating voltage between the ECU terminal No.11 and No.9. Maintain the engine speed ia at idle while the coolant temperature is over 80 °C.
If the measured value is not within the specified value, the possible cause may be in cable, oxygen sensor or ECU.
Oxygen Sensor Heating Current Consumption
Inspection
1. Measure the oxygen sensor heating current consumption between the ECU terminal No.9 and No.5 while the ignition switch is in "ON" position. If the measured value is not within the specified value, the possible cause may be in cable, oxygen sensor or ECU.
Specified Value 0.2 - 2.0 A
Specified Value -0.2 - 1.0 V
Specified Value 11 - 14

1 Artificial Resin Housing
2 Metal Housing
3 NTC (negative temperature coefficient) Resistor
Removal & Installation Procedure
1. Remove the pressure by opening the pressure cap in the coolant subtank.
2. Disconnect the connector and remove the coolant temperature sensor. Installation Notice Replace the seals with new one.
3. Installation should follow the removal procedure in the reverse order.
4. Check for leaks at each connections after starting the engine. 4 Connector
5 Coolant Temperature Sensor
Tightening Torque 18 - 22 Nm

1F1-76 M162 ENGINE CONTROLS 2. Measure the resistance between the coolant temperaturesensor terminal No.1 and No.4 with the coolant temperature sensor disconnected.
Inspection 1. Measure the coolant sensor input voltage between the ECU
terminal No.79 and No.78 while the ignition switch in "ON" position. Notice Replace wiring and coolant temperature sensor if out of specified value. allowable error :
