Notice Replace the fuel pump relay if the measured value is over 9A.
Notice Check the fuel filter and fuel line when the fuel delivery is not within specified value.
Measure the Current Consumption of Fuel Pump
1. Remove the fuel pump relay from fuse and relay box in trunk, and turn the ignition switch to "ON" position.
2. Using a multi-tester, measure the current consumption by connecting the terminal No.1 and No.3 of pump.
Measure the Fuel Delivery From the Fuel Pump
1. Disconnect the return pipe from fuel distributor and insert
the appropriate hose into it.
2 . Place the hose end into the beaker with the minimum capacity of 1Liter.
3. Turn the ignition switch to "ON" position.
4. Connect the terminal No.33 and No.5 of ECU with a service wire.
5. Measure the fuel delivery from the fuel pump.
1Liter/max.35sec.

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
