(2) Fuel Pump (for Reformer)
• Firstly check the connector voltage, secondly check the other wires continuity, then finally check the
pump resistance.

Connector Voltage
1. Disconnect the connector, and turn the main key switch "ON"
position.
2. Measure the voltage with a voltmeter across the terminals
shown in the table below.
3. If the reference value is not indicated as shown in the table
below, check the relating electric circuit.

Sensor Resistance
1. Measure the resistance with an ohmmeter across the terminals
shown in the table below.
2. If the reference value is not indicated, the fuel pump (for
reformer) is faulty.
