Note
-
• Perform the following test only when directed.
Resistance Inspection
1. Disconnect the negative battery cable.
2. Remove the supply pump. (See SUPPLY PUMP REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)
3. Measure the resistance between the fuel temperature sensor terminals using an ohmmeter.
-
• If not as specified, repair the supply pump. (See SUPPLY PUMP INSPECTION [MZR-CD (RF Turbo)].)
