Note
• Perform the following test only when directed.
Resistance Inspection
1. Disconnect the negative battery cable.
2. Remove the supply pump. (See F2–53 SUPPLY PUMP REMOVAL/INSTALLATION.)
3. Measure the resistance between the fuel
temperature sensor terminals using an
ohmmeter.
• If not as specified, repair the supply pump.
(See F2–54 SUPPLY PUMP INSPECTION.)
Specification
